Audio Editor VST Compatible

Audacity is a free audio editor. You can record sounds, play sounds, import and export WAV, AIFF, and MP3 files, and more. Use it to edit your sounds using Cut, Copy and Paste (with unlimited Undo), mix tracks together, or apply effects to your recordings. It also has a built-in amplitude envelope editor, a customizable spectrogram mode and a frequency analysis window for audio analysis applications. Built-in effects include Bass Boost, Wahwah, and Noise Removal, and it also supports VST plug-in effects.

Audacity Audacity Audacity v 2.0.5 Oct 22, 2013 MacOS X UB
Bug fixes

Shaped dither was corrupted and too loud on all stereo exports except FLAC.
Keyboard Preferences: some Edit and Align commands for different sub-menus showed the same name.
Recordings stopped with "Stop and Set Cursor" shortcut could not be undone.
In locales that use comma for decimal separator:
Text boxes with slider in Nyquist effects only produced whole numbers when using comma to enter a fractional number. Text boxes without slider still have this problem.
Built-in generators produced silence after running a Nyquist effect.
(Windows) When first changing to Windows WASAPI host, the input volume slider in Mixer Toolbar was enabled when it should have been permanently disabled.
(Windows) On some machines, launching Audacity then recording from the current Device Toolbar input would not record until the input was reselected.
(OS X) Frequent crashes occurred on importing audio files on some machines.
(OS X) Files did not open using Finder "Open with", double-clicking the file or dragging the file to the Audacity icon.
(Linux 64-bit) Fixed a crash when using Equalization.
(Linux) It was not possible to open an effect or other dialog then navigate through the dialog using TAB.
(Linux) The Play shortcut did not play a read-directly WAV, AIFF or FLAC import if the warning for importing uncompressed files appeared.

Changes and Improvements

Tracks Menu:
The separate commands that aligned track start or end with the cursor or with selection start are combined into "Cursor/Selection Start" commands.
"Align and Move Cursor" renamed to "Move Selection when Aligning".
Label Tracks:
Labels Editor now allows empty labels to be saved on closing the editor.
TAB and SHIFT+TAB when the label track has focus now always move forwards or backwards respectively to the nearest label.
(Windows) On a very few machines, the Windows WDM-KS low latency audio host introduced in Audacity 2.0.4 caused Audacity to hang or the computer to crash. WDM-KS has been removed from 2.0.5 until it can be safely enabled.
(Windows and OS X) Screen reader improvements for Install VST Effects dialog.
(OS X) Audio Unit plug-ins detected by Audacity on launch are now not loaded until chosen from the Effect menu. This should speed up launch and avoid crashes at launch due to misbehaving Audio Units.
(Linux) Update to PortAudio r1910 fixes memory and other bugs under ALSA.
(Linux) Applied fix for wxGTK 2.8.12 bug which resulted in loss of Audacity's menu bar (or visual corruption under Unity) on Debian-based systems.
Audacity Audacity v 2.0.4 Sep 9, 2013 MacOS X UB
Bug fixes

Keyboard Preferences: Shortcuts for Generators, Effects and Analyzers were not exported. All imported shortcut changes were discarded.
Equalization curves were corrupted in Graphic EQ mode after switching to/from Draw Curves or after running the effect then reopening it.
Change Pitch displayed corrupted values when reducing pitch or editing "from" Frequency. Detection was very inaccurate at high sample rates.
Bass Boost no longer clips if the track contains 32-bit audio.
Auto Duck was excessively slow on older machines.
(Windows) Exported MP3 comments tags were not seen by Windows programs.
(Windows and OS X) Audacity crashed if you used system quit before file import was complete.
(Linux) Equalization crashed Audacity if the XML file was corrupted.
(Linux) When configuring effect parameters in "Edit Chains", "Preview" (not intended to be functional) caused a crash.
(Linux) LICENSE.txt and README.txt were wrongly installed in /usr/local/share/doc instead of /usr/local/share/doc/audacity/ .
Accessibility: ENTER did not toggle selectedness of a label track unless a label was selected.
Numerous other interface fixes.

Changes and Improvements

New "Reverb" effect to replace GVerb, based on the original "Freeverb".
New View > Go to Selection Start and Go to Selection End commands.
New Tracks > Align End to End command to append existing tracks to each other.
Change Tempo now supports fractional BPM.
Plot Spectrum now supports FFT sizes up to 65536.
WAV files now support "Album Title", "Track Number" and "Genre" LIST INFO tags and also support ID3 tags.
Handle a bug in older iPods or some OS X applications that cause them to refuse AIFF files whose metadata contains an uneven number of characters,
(Windows) Added support for "Windows WDM-KS" host which can provide very low latencies if you reduce "Audio to Buffer" in Recording Preferences.
(Windows Vista and later) You can now record computer playback by choosing the new "Windows WASAPI" host in Device Toolbar then a "loopback" input.
(Windows and Mac OS X): VST scanning dialog now replaced with a dialog for choosing which VST effects to load.

sounds Audacity v 2.0.2 Aug 24, 2012 MacOS X UB
A significant bug that caused clicks on split lines has been fixed, and there are improvements to several toolbars and to some Nyquist effects.
audio Audacity v 2.0.1 Jul 2, 2012 MacOS X UB
Bug fixes
Interface

Selection Toolbar: a value for the previous whole second displayed if the value was close to a whole second.
Finding zero crossings could cause the selection to expand into white space at either side of the clip.
Clips did not drag to another track if mouse was over a selection.
Mixer Board: Rendering four tracks resulted in a redundant Track Strip followed by a crash.

Imports, Exports and Files

Exporting to WAV or AIFF led to a "Libsndfile says" error or corrupted output due to order of metadata in imported files.
(Mac) Fixed crashes importing MP3 files on PPC machines.
(Linux Ubuntu) .Aup files could not be associated with Audacity (they opened in the web browser instead).

Effects and Analysis

Normalize: Fixed issues where normalization could be to wrong value if applied with DC offset correction, or if applied to "read-directly" WAV and AIFF files before On-Demand completed.
Sliding Time Scale: fixed an audible discontinuity at the beginning of the processed selection; fixed a serious quality problem on Linux 64-bit.

Other miscellaneous bug fixes

including fix to prevent zooming with mouse wheel or ball scrolling the content off-screen.

Changes and Improvements

Shortcuts can now be added in Keyboard Preferences to items in the Generate, Effect or Analyze menus, including user-added plug-ins.
Nyquist Effect plug-ins can now be added to Chains.
New "Paulstretch" effect for extreme slowdown without pitch change.
New "Sample Data Export" Analyze effect for exporting a file containing amplitude values for each sample in the selection.
New Preference (off by default) to import files On-Demand (without seek ability) when using the optional FFmpeg library.
New Preference (off by default) to retain labels when deleting a selection that snaps to the label without extending past it.
(Windows installer) New option to reset Preferences on next launch.
(Mac) Audacity now has excellent compatibility with the VoiceOver screen reader. For details, please see http://manual.audacityteam.org/help/manual/man/accessibility.html#mac.
CleanSpeech Mode (no longer supported) will not now be enabled even if it was enabled by an earlier version of Audacity.
Added Serbian (Latin and Cyrillic) translations.
effects Audacity v 2.0.0 Mar 14, 2012 MacOS X UB
Bug fixes

Interface
Fixed playback speed and synchronization problems when dragging clips or tracks between tracks having different sample rates.
(Windows) Removed a crash risk where shortcuts could be used to record or import in one project while importing or exporting in another.

Imports and Exports
Fixed crashes when changing the sample format of read-directly WAV or AIFF files using the Track Drop-Down Menu.
Fixed a crash importing MP3 files that had duplicate metadata tags (this is a bug in current libsndfile which has been patched in Audacity; MP3 files mislabeled as WAV which have duplicate tags will still crash Audacity on Linux if Audacity has been compiled against an affected version of system libsndfile).
Fixed an issue where excessively high or corrupted sample values in the audio could corrupt exports from the start of the problem for the rest of the file, and could corrupt the rest of the project.
(Linux) Fixed Audacity could not be compiled against FFmpeg 0.7.x and 0.8.x.

Effects and Analysis
Fixed crash on launch when using "Ambisonic Decoders (PC)" VST plug-ins and other plug-ins that enable additional floating point exceptions.
Fixed Plot Spectrum background could be transparent on some machines.
Bug fixes for Click Track, High Pass, Low Pass and Vocal Remover.
Chirp, Tone and Silence generators now remember their settings.

Other miscellaneous bug fixes

Changes and Improvements
New Interface preference to show the track name in the display (this is off by default).
Longer default Playback preference for effects preview and preview before cut.
Restored use of Page Up and Page Down to scroll horizontally.
editor Audacity v 1.3.14beta Dec 13, 2011 MacOS X UB
Bug fixes for:

Interface:

Excessive delay occurred when typing into labels in long projects.
Last digit of TimeText controls could not be manipulated in some formats.
(Windows, OS X) Play and Record shortcuts did not work after clicking in Device Toolbar.
(OS X, Linux) Crash occurred if Toolbars were reset during playback or recording.

Imports and Exports:

MP2 files were not importable without FFmpeg library or an import rule.
Files that could only be imported using FFmpeg imported as noise with no error message if FFmpeg was not available.
Files containing PCM audio but an incorrect extension (such as MP3) caused a freeze.

Effects and Analysis:

An empty command could be added to a Chain which then displayed a Nyquist error message when run.
Plot Spectrum didn't preserve signal level if multiple tracks were analyzed.

Other bug fixes:

Audacity has been provisionally fixed so that it can no longer create block files longer than the sample format or project format allows, and can no longer delete these, which led to data loss. Any overlong blocks found are preserved but "orphaned", so will appear as silence.
Orphan block files were wrongly reported if cutting or copying to the clipboard then reopening the project in the same session.
Fixed some crashes and incorrect movement of audio when dragging tracks.
(Windows) Data loss is now prevented when encountering a corrupted .aup file created in ANSI builds.
(Linux) Restore building if USE_PORTMIXER is not defined.

Changes and Improvements:

Normalize: Faster processing and improved interface. Left-right balance in unsplit stereo tracks is now preserved by default, with a checkbox option provided to process stereo channels independently.
Spectrograms now allow window sizes up to 32768 and frequencies up to half the sample rate (the maximum possible).
Mix and Render now preserves clip length by not rendering white space between time zero and first audio, and preserves audio before time zero. To retain silence before the audio starts, generate silence after render.
Grouped some Edit Menu items into "Remove Audio" and "Clip Boundaries".
CleanSpeech Mode removed from Interface Preferences (it still runs if it was enabled in a previous Audacity but can only be turned off there).
(OS X) Added support for AudioUnit MusicEffects (but no MIDI support).
(Linux) Set the per-user files directory per the program name set in configure.
(Linux) Changed the default location of the Audacity temporary directory to be in /var/tmp not /tmp, so preserving the directory between reboots.
built-in Audacity v 1.3.13beta Apr 12, 2011 MacOS X UB
Bug fixes for:

Interface:

* Cutting or copying from a track at a given sample rate into a track at another rate resulted in speed-changed audio.
* Generating inside a clip could modify the clip length or create spurious clips.
* Recorded stereo tracks were only half the height of imported or generated stereo tracks. Imported stereo files had a "1" appended to the track name.
* Edit > Region Save did not save the cursor position.
* (Windows) Projects crashed when clicking rapidly inside the interface or when applying repeated effects towards the end of audio tracks.
* (Windows) Some Unicode characters could not be typed into labels,or caused a freeze using some input methods.
* (OS X) Crash when quitting an empty project window, or when closing the main project window while a progress dialog was on screen.
* Numerous other interface fixes including Dependencies dialog, Keyboard Preferences and spurious lines drawn on waveform.

Imports and Exports:

* Support added for later versions of the optional FFmpeg library up to current FFmpeg HEAD. This should significantly improve FFmpeg support on Linux. FFmpeg downloads for Windows and Mac updated to v0.6. This fixes mono AAC files importing as stereo, though current 0.5 versions of FFmpeg will still work.
* Both FFmpeg and LAME should now be properly detected even when other versions of those libraries exist on the system.
* New warning (on by default) for importing uncompressed audio files. Better error messages when read-directly uncompressed files are missing.
* Imported ID3v2 metadata tags were removed when exporting without the Metadata Editor appearing (for example, when using an export command in Chains). Note: As a result of this fix, ID3v1 tags must now be written by exporting using (external program) and an installed LAME.
* U-Law/A-Law files with WAV headers now use the standard 18 byte fmt chunk, so should now be recognised by most telephony applications.
* Variable bit rate MP3s exported using "MP3 Files" were larger than necessary because using the bit reservoir was disabled.
* (OS X) Files imported from iTunes could create invalid characters in the .aup project file, causing an error when re-opening the project. Note: An error "reference to invalid character number" will still occur if re-opening a project created in previous Betas that contains such characters. To fix the issue, open a back-up copy of the .aup file in a text editor, turn off word wrap, then in the line indicated in the error message, remove the string of characters that starts with &# and ends with a semi-colon (;).

Other bug fixes:

* Nyquist effects: fixes for crashes, incorrect slider behaviour and better support for backslashes, double quotes and Unicode characters.
* (Windows and OS X) Processing of VST effects was substantially slower than in previous versions of Audacity.
* (OS X 10.5 PPC) A first-time installation of Audacity Beta would hang on launch if VST effects were detected.
* (Linux) Recordings made with the pulse device crashed or stalled when using overdub and/or software playthrough.
* (Linux) Play-at-Speed crashed at 0.08 speed or lower if Audacity was configured with libsamplerate.

Changes and improvements:

* Control Toolbar renamed to Transport Toolbar.
* Device Toolbar (on by default) now contains all input and output device choices, including host and recording channels. Input/output choices are no longer in Mixer Toolbar on Windows XP or some older operating systems. New Transport > Rescan Audio Devices menu item to refresh the device list.
* New "Sync-Lock Tracks" feature (turned on in the Tracks menu) to allow groups of audio and/or label tracks to retain synchronisation when the track length changes.
* Equalization: New "Manage Curves" dialog for importing and exporting curves.
* Noise Removal: New "Sensitivity" slider to adjust the noise threshold, and new option to isolate noise.
* New "Extended Import" Preferences for specifying different importers to open specific file extensions.
* Improved Automatic Crash Recovery with all project changes autosaved.
* MIDI tracks can be vertically zoomed, time shifted and display bar lines. Note: the channel selection buttons are not available in 1.3.13.
* (Windows and Linux) The window Close button and other system close or shutdown commands now quit on closing the last window. File > Close now always clears to a new, empty project.
* (OS X) Simpler installer with top-level "Audacity" folder.

* FFmpeg custom export window too large on 800 x 600 resolution monitors
* Projects froze if files imported via On-Demand were no longer available
* (Linux) WAV/AIFF exports were corrupted if overwriting an aliased file which had been imported using the command line

Labels:
* Cutting or deleting a region in the waveform and label track did not move the labels in advance of the cut
* Incorrect behavior snapping to labels and boundaries with Snap To enabled

    Text boxes with slider in Nyquist effects only produced whole numbers when using comma to enter a fractional number. Text boxes without slider still have this problem.
    Built-in generators produced silence after running a Nyquist effect.
    (Windows) When first changing to Windows WASAPI host, the input volume slider in Mixer Toolbar was enabled when it should have been permanently disabled.
    (Windows) On some machines, launching Audacity then recording from the current Device Toolbar input would not record until the input was reselected.
    (OS X) Frequent crashes occurred on importing audio files on some machines.
    (OS X) Files did not open using Finder "Open with", double-clicking the file or dragging the file to the Audacity icon.
    (Linux 64-bit) Fixed a crash when using Equalization.
    (Linux) It was not possible to open an effect or other dialog then navigate through the dialog using TAB.
    (Linux) The Play shortcut did not play a read-directly WAV, AIFF or FLAC import if the warning for importing uncompressed files appeared.

    Changes and Improvements

    Tracks Menu:
    The separate commands that aligned track start or end with the cursor or with selection start are combined into "Cursor/Selection Start" commands.
    "Align and Move Cursor" renamed to "Move Selection when Aligning".
    Label Tracks:
    Labels Editor now allows empty labels to be saved on closing the editor.
    TAB and SHIFT+TAB when the label track has focus now always move forwards or backwards respectively to the nearest label.
    (Windows) On a very few machines, the Windows WDM-KS low latency audio host introduced in Audacity 2.0.4 caused Audacity to hang or the computer to crash. WDM-KS has been removed from 2.0.5 until it can be safely enabled.
    (Windows and OS X) Screen reader improvements for Install VST Effects dialog.
    (OS X) Audio Unit plug-ins detected by Audacity on launch are now not loaded until chosen from the Effect menu. This should speed up launch and avoid crashes at launch due to misbehaving Audio Units.
    (Linux) Update to PortAudio r1910 fixes memory and other bugs under ALSA.
    (Linux) Applied fix for wxGTK 2.8.12 bug which resulted in loss of Audacity's menu bar (or visual corruption under Unity) on Debian-based systems.
    Audacity Audacity v 2.0.4 Sep 9, 2013 Windows
    Bug fixes

    Keyboard Preferences: Shortcuts for Generators, Effects and Analyzers were not exported. All imported shortcut changes were discarded.
    Equalization curves were corrupted in Graphic EQ mode after switching to/from Draw Curves or after running the effect then reopening it.
    Change Pitch displayed corrupted values when reducing pitch or editing "from" Frequency. Detection was very inaccurate at high sample rates.
    Bass Boost no longer clips if the track contains 32-bit audio.
    Auto Duck was excessively slow on older machines.
    (Windows) Exported MP3 comments tags were not seen by Windows programs.
    (Windows and OS X) Audacity crashed if you used system quit before file import was complete.
    (Linux) Equalization crashed Audacity if the XML file was corrupted.
    (Linux) When configuring effect parameters in "Edit Chains", "Preview" (not intended to be functional) caused a crash.
    (Linux) LICENSE.txt and README.txt were wrongly installed in /usr/local/share/doc instead of /usr/local/share/doc/audacity/ .
    Accessibility: ENTER did not toggle selectedness of a label track unless a label was selected.
    Numerous other interface fixes.

    Changes and Improvements

    New "Reverb" effect to replace GVerb, based on the original "Freeverb".
    New View > Go to Selection Start and Go to Selection End commands.

    Handle a bug in older iPods or some OS X applications that cause them to refuse AIFF files whose metadata contains an uneven number of characters,
    (Windows) Added support for "Windows WDM-KS" host which can provide very low latencies if you reduce "Audio to Buffer" in Recording Preferences.
    (Windows Vista and later) You can now record computer playback by choosing the new "Windows WASAPI" host in Device Toolbar then a "loopback" input.
    (Windows and Mac OS X): VST scanning dialog now replaced with a dialog for choosing which VST effects to load.
    (Linux) CTRL + ALT can now be used to smooth samples in Draw Tool.
    Modules Preferences replaced with a dialog on launch of Audacity enabling you to choose which modules to load.
    sounds Audacity v 2.0.2 Aug 24, 2012 Windows
    A significant bug that caused clicks on split lines has been fixed, and there are improvements to several toolbars and to some Nyquist effects.
    audio Audacity v 2.0.1 Jul 2, 2012 Windows
    Bug fixes
    Interface

    Selection Toolbar: a value for the previous whole second displayed if the value was close to a whole second.
    Finding zero crossings could cause the selection to expand into white space at either side of the clip.
    Clips did not drag to another track if mouse was over a selection.
    Mixer Board: Rendering four tracks resulted in a redundant Track Strip followed by a crash.

    Imports, Exports and Files

    Exporting to WAV or AIFF led to a "Libsndfile says" error or corrupted output due to order of metadata in imported files.
    (Mac) Fixed crashes importing MP3 files on PPC machines.
    (Linux Ubuntu) .Aup files could not be associated with Audacity (they opened in the web browser instead).

    Effects and Analysis

    Normalize: Fixed issues where normalization could be to wrong value if applied with DC offset correction, or if applied to "read-directly" WAV and AIFF files before On-Demand completed.
    Sliding Time Scale: fixed an audible discontinuity at the beginning of the processed selection; fixed a serious quality problem on Linux 64-bit.

    Other miscellaneous bug fixes

    including fix to prevent zooming with mouse wheel or ball scrolling the content off-screen.

    Changes and Improvements

    Shortcuts can now be added in Keyboard Preferences to items in the Generate, Effect or Analyze menus, including user-added plug-ins.
    Nyquist Effect plug-ins can now be added to Chains.
    New "Paulstretch" effect for extreme slowdown without pitch change.
    New "Sample Data Export" Analyze effect for exporting a file containing amplitude values for each sample in the selection.

    CleanSpeech Mode (no longer supported) will not now be enabled even if it was enabled by an earlier version of Audacity.
    Added Serbian (Latin and Cyrillic) translations.
    effects Audacity v 2.0.0 Mar 14, 2012 Windows
    Bug fixes

    Interface
    Fixed playback speed and synchronization problems when dragging clips or tracks between tracks having different sample rates.
    (Windows) Removed a crash risk where shortcuts could be used to record or import in one project while importing or exporting in another.

    Imports and Exports
    Fixed crashes when changing the sample format of read-directly WAV or AIFF files using the Track Drop-Down Menu.
    Fixed a crash importing MP3 files that had duplicate metadata tags (this is a bug in current libsndfile which has been patched in Audacity; MP3 files mislabeled as WAV which have duplicate tags will still crash Audacity on Linux if Audacity has been compiled against an affected version of system libsndfile).
    Fixed an issue where excessively high or corrupted sample values in the audio could corrupt exports from the start of the problem for the rest of the file, and could corrupt the rest of the project.
    (Linux) Fixed Audacity could not be compiled against FFmpeg 0.7.x and 0.8.x.

    Effects and Analysis
    Fixed crash on launch when using "Ambisonic Decoders (PC)" VST plug-ins and other plug-ins that enable additional floating point exceptions.
    Fixed Plot Spectrum background could be transparent on some machines.
    Bug fixes for Click Track, High Pass, Low Pass and Vocal Remover.

    Longer default Playback preference for effects preview and preview before cut.
    Restored use of Page Up and Page Down to scroll horizontally.
    editor Audacity v 1.3.14beta Dec 13, 2011 Windows
    Bug fixes for:

    Interface:

    Excessive delay occurred when typing into labels in long projects.
    Last digit of TimeText controls could not be manipulated in some formats.
    (Windows, OS X) Play and Record shortcuts did not work after clicking in Device Toolbar.
    (OS X, Linux) Crash occurred if Toolbars were reset during playback or recording.

    Imports and Exports:

    MP2 files were not importable without FFmpeg library or an import rule.
    Files that could only be imported using FFmpeg imported as noise with no error message if FFmpeg was not available.
    Files containing PCM audio but an incorrect extension (such as MP3) caused a freeze.

    Effects and Analysis:

    An empty command could be added to a Chain which then displayed a Nyquist error message when run.
    Plot Spectrum didn't preserve signal level if multiple tracks were analyzed.

    Other bug fixes:

    Audacity has been provisionally fixed so that it can no longer create block files longer than the sample format or project format allows, and can no longer delete these, which led to data loss. Any overlong blocks found are preserved but "orphaned", so will appear as silence.
    Orphan block files were wrongly reported if cutting or copying to the clipboard then reopening the project in the same session.
    Fixed some crashes and incorrect movement of audio when dragging tracks.
    (Windows) Data loss is now prevented when encountering a corrupted .aup file created in ANSI builds.
    (Linux) Restore building if USE_PORTMIXER is not defined.

    Changes and Improvements:

    Normalize: Faster processing and improved interface. Left-right balance in unsplit stereo tracks is now preserved by default, with a checkbox option provided to process stereo channels independently.
    Spectrograms now allow window sizes up to 32768 and frequencies up to half the sample rate (the maximum possible).
    Mix and Render now preserves clip length by not rendering white space between time zero and first audio, and preserves audio before time zero. To retain silence before the audio starts, generate silence after render.
    Grouped some Edit Menu items into "Remove Audio" and "Clip Boundaries".
    CleanSpeech Mode removed from Interface Preferences (it still runs if it was enabled in a previous Audacity but can only be turned off there).
    (OS X) Added support for AudioUnit MusicEffects (but no MIDI support).
    (Linux) Set the per-user files directory per the program name set in configure.
    (Linux) Changed the default location of the Audacity temporary directory to be in /var/tmp not /tmp, so preserving the directory between reboots.
    built-in Audacity v 1.3.13beta Apr 12, 2011 Windows
    Bug fixes for:

    Interface:

    * Cutting or copying from a track at a given sample rate into a track at another rate resulted in speed-changed audio.
    * Generating inside a clip could modify the clip length or create spurious clips.
    * Recorded stereo tracks were only half the height of imported or generated stereo tracks. Imported stereo files had a "1" appended to the track name.
    * Edit > Region Save did not save the cursor position.
    * (Windows) Projects crashed when clicking rapidly inside the interface or when applying repeated effects towards the end of audio tracks.
    * (Windows) Some Unicode characters could not be typed into labels,or caused a freeze using some input methods.
    * (OS X) Crash when quitting an empty project window, or when closing the main project window while a progress dialog was on screen.
    * Numerous other interface fixes including Dependencies dialog, Keyboard Preferences and spurious lines drawn on waveform.

    Imports and Exports:

    * Support added for later versions of the optional FFmpeg library up to current FFmpeg HEAD. This should significantly improve FFmpeg support on Linux. FFmpeg downloads for Windows and Mac updated to v0.6. This fixes mono AAC files importing as stereo, though current 0.5 versions of FFmpeg will still work.
    * Both FFmpeg and LAME should now be properly detected even when other versions of those libraries exist on the system.
    * New warning (on by default) for importing uncompressed audio files. Better error messages when read-directly uncompressed files are missing.
    * Imported ID3v2 metadata tags were removed when exporting without the Metadata Editor appearing (for example, when using an export command in Chains). Note: As a result of this fix, ID3v1 tags must now be written by exporting using (external program) and an installed LAME.
    * U-Law/A-Law files with WAV headers now use the standard 18 byte fmt chunk, so should now be recognised by most telephony applications.
    * Variable bit rate MP3s exported using "MP3 Files" were larger than necessary because using the bit reservoir was disabled.
    * (OS X) Files imported from iTunes could create invalid characters in the .aup project file, causing an error when re-opening the project. Note: An error "reference to invalid character number" will still occur if re-opening a project created in previous Betas that contains such characters. To fix the issue, open a back-up copy of the .aup file in a text editor, turn off word wrap, then in the line indicated in the error message, remove the string of characters that starts with &# and ends with a semi-colon (;).

    Other bug fixes:

    * Nyquist effects: fixes for crashes, incorrect slider behaviour and better support for backslashes, double quotes and Unicode characters.
    * (Windows and OS X) Processing of VST effects was substantially slower than in previous versions of Audacity.
    * (OS X 10.5 PPC) A first-time installation of Audacity Beta would hang on launch if VST effects were detected.
    * (Linux) Recordings made with the pulse device crashed or stalled when using overdub and/or software playthrough.
    * (Linux) Play-at-Speed crashed at 0.08 speed or lower if Audacity was configured with libsamplerate.

    Changes and improvements:

    * Control Toolbar renamed to Transport Toolbar.
    * Device Toolbar (on by default) now contains all input and output device choices, including host and recording channels. Input/output choices are no longer in Mixer Toolbar on Windows XP or some older operating systems. New Transport > Rescan Audio Devices menu item to refresh the device list.
    * New "Sync-Lock Tracks" feature (turned on in the Tracks menu) to allow groups of audio and/or label tracks to retain synchronisation when the track length changes.
    * Equalization: New "Manage Curves" dialog for importing and exporting curves.
    * Noise Removal: New "Sensitivity" slider to adjust the noise threshold, and new option to isolate noise.
    * New "Extended Import" Preferences for specifying different importers to open specific file extensions.
    * Improved Automatic Crash Recovery with all project changes autosaved.
    * MIDI tracks can be vertically zoomed, time shifted and display bar lines. Note: the channel selection buttons are not available in 1.3.13.
    * (Windows and Linux) The window Close button and other system close or shutdown commands now quit on closing the last window. File > Close now always clears to a new, empty project.
    * (OS X) Simpler installer with top-level "Audacity" folder.

    using the command line

    Other bug fixes:
    * When using non-English languages, Generate effects truncated the selected region
    * Mice with high-precision scroll-wheels could cause a crash
    * Changing recording preferences using the Transport menu did not update the menu in other open projects
    * (Windows 7) Clicking in a file open or save dialog caused files or folders to disappear from the list, and file filtering was broken

    Changes and improvements:
    * A hover tooltip is now provided if the Mixer Toolbar input selector cannot control the system slider for the selected input.
    * More intuitive behavior when moving and resizing labels by dragging

    * Export Multiple: new option to use a numerical prefix before existing label or track names; "Success" dialog now resizable
    * New Equalization preset "Inverse RIAA", with new button to invert other curves
    * Timer Record now remembers last scheduled duration
    * Meter Toolbar can now be made much narrower, and so more suitable for vertical orientation
    * New Preferences choice for "System" language which is used on first run instead of asking user to choose language
    * Warning now provided if WAV/AIFF exports are not successfully completed
    * (Linux) Improved icon set in compliance with freedesktop.org Icon Theme Specification 0.6

    I downloaded 'Audacity', because open source geek friends keep telling me that it's 'great'.. It is platform agnostic, open-source, free, and supports VST plugins.... Sounds good so far.. I then spent the last 2 hours mucking around with it.
    Man... what a disappointment. It has about the same level of functionality as SoundEdit 16 on a Mac from the early to mid nineties, albeit with proper undo. Here are some of its limitations
    1) No real-time FX.... only file based processing with a 2-3 second preview. GUIs for VST plugins also not working at present, resulting in very non-intuitive parameter lists and generic faders.
    2) No 'region' capturing, or clip based editing... you have to chop into the waveform and do copy/pastes to make a simple loop.. no way of slipping clips around in a track - you can only slip the whole track in time.... very SoundEdit 16, very primitive, unusable.
    3) Every time you import a new audio file, Audacity creates a new track. This is annoying. There is no 'audio clips bin' like most basic editors and no dragging and dropping of clips into the timeline from a 'library', which is a fairly basic requirement for any sort of editing.
    4) You can cut and paste selected audio from one track to another, but when you paste, Audacity automatically butts the copied audio up against the previous and you are not able to paste at a point beyond the end of the previous audio, nor slip the pasted audio in the timeline after you have pasted it. The only way of creating a gap between the previous audio and the audio you wish to paste is to 'generate silence' from a menu before pasting. Once you have done this, you still can't easily vary the silence gap or slip the position of the pasted audio. To shorten the gap (bring the pasted clip earlier in the session) you have to select some silence and 'delete' it.... then the pasted clip slips back closer to the previous.... You can't do proper editing this way and you will end up tearing your hair out fairly swiftly!!
    5) There is no such thing as a cross-fade edit in a track. This makes cutting and pasting audio between tracks unworkable. To achieve cross-fades (even small ones) you need to use two tracks and write volume automation on the outgoing and incoming audio. I cannot see how you are able to do any real editing in this kind of environment. Even simple 2 track editing becomes difficult.
    6) No video clip import/sync
    7) No midi file editing or playback, or support for VST instruments
    8) A frustratingly clunky volume automation editor, where you can't nail the break points properly without zooming in to micro level.
    9) No decent navigation keyboard shortcuts, like for example jumping to the beginning or end of a selection when zoomed in, or parking the cursor at the end of a clip etc... or selecting from a point to the beginning or end of a clip. The basic editing necessities aren't there - you need basic keyboard shortcuts for navigation and selection... if you are expected to shift click, drag and zoom everything, you will go completely crazy in a short space of time.
    I then went to the Audacity Wiki server to look at some of the discussion... There is a development wishlist, which seems to have some strange priorities with some of the basic issues above not even appearing... There are also occasional examples of excessive hubris such as this Audacity developers statement about Pro Tools in the comparisons page - "[pro tools is] cumbersome at times, but the basic functions of Audacity closely emulate those of Pro Tools",
    I don't think so pal.... (please see list of limitations above!!!!) and i really want to believe you!
    There are a couple of good things, such as support for 96khz/32bit, capacity to have files of different sample rates in a session, mp3 and ogg vorbis export, 'batch like' processing for exports and an undo history list - but that's about it.
    Some may say... well what can you expect for a free, open-source tool? Well, fair enough, the price is right and the politics are too, but the truth of the matter is that I would find this tool almost impossible to deploy into even a beginner's lab, as it lacks the simple features which allow people to grasp some of the basic principles of non-linear audio editing and production.

    Sorry to be so harsh.
    my problem is that i can't download it due to very poor host "distributors".
    i've tried a very early version of this software and found it very promising.
    soundforge.net sucks/at least needs a server that can deal with it's "traffic"!
    an open letter to soundforge;
    stream your clients. don't force me to endure computer game adverts whilst i'm trying to download a peice of potentially "serious" software.
    if you host a download, make sure it actually functions.
    all pop-up/banner oriented sites will go the same way as junk mail sooner or later. you already know this. use your brains! it's what you're paid for!!
    harsh comments but no hard feelings,
    apologies for any lack of inarticulacy,
    best wishes,
    paul waller.

    Only one problem: it doens't work with my external audio device. I use an Edirol FA-101. Quite a few applications that I've come across have neglected support for this device, even though it uses no special drivers or fancy features- it's just straight CoreAudio.

    Yeah, this is becoming a nice piece of software! Congrats to the developers. There are a few things I would like to see implemented, like a master level meter to tell you when your mix is clipping. But a great little audio editor to go along with Pro Tools. I use it to do stuff like edit away from my Mbox and import multichannel AIFFs recorded in MaxMSP. Since version 1.2 Audacity has been extremely stable for me!

    I've made some really good recordings with just this and the pre-amps on a yamaha MG10/2. Tracks clean up very well. I was gonna buy protools but now i don't really have a reason to.

    Pour un logiciel gratuit, je le trouve passablement performant. Bien sûr, je suis un amateur, mais il comble mes besoins. Sur certains plans, il égale des logiciels payants. Donc bravo aux concepteurs!

    C'est un peu juste comme appli, l'ergonomie n'est pas terrible, il manque des raccourcis évidents et ca devient vite énervant. Si il y a avait une fonction de split sur seuil ce serait cool mais la non.

    Pour le prix c'est largement bien pour s'initier à la bidouille audio. Utilisation très simple.

    Super logiciel pour de l'édition sonore basique

    Le problème c'est pour exporter les fichiers en aiff, j'aimerais bien trouver un convertisseur. à part ça, c'est gratuit, c'est dans mes prix et question plantage, faut savoir s'y prendre avec lui. bravo au concepteur!

    Il plante, il ne veut pas ouvrir certain fichier, il a du mal avec certain VST
