SignalScope Pro

Version 3.0.5 corrects an issue that halted live updates of bar meters and fixes a bug that could potentially cause the app to crash.

Version 3.0.4 is a maintenance release.

* Version 3 sports an improved user interface.
* Up to two tools of each type may be added to a project.
* User preferences are available for individual tools.
* Default audio device configurations, including channel labels, units, and sensitivity can be saved.
* Virtual input channels can be added to audio input devices. Two-channel signal arithmetic (add, subtract, multiply) is now supported.
* Arbitrary FFT lengths may be specified in FFT-based analysis tools.
* The Spectrogram supports log frequency scales and real-time 3D spectrogram display.
* Version 3 includes various other improvements over previous versions.
* SignalScope Pro may now be purchased and maintained through the Mac App Store.

* Channel count changes for multi-channel audio devices are handled dynamically, avoiding potential crashes.
* Several other minor bugs have been corrected.

* Output channels of certain multi-channel audio interfaces, such as the MOTU UltraLite mk3, are properly enumerated.
* Audio device channel gains on certain devices, such as the Wavelength Proton USB DAC, are properly restored when opening project files.

Version 2.1.8 is a maintenance release that improves the stability of the application.

Version 2.1.7 is a maintenance release that improves the stability of the application.

The new updates include improved Leopard compatibility and stability enhancements. These updates are recommended for all users of SignalScope/Pro 2.x or SignalSuite 3.x.

* Input channel selection now relies on checkboxes and radio buttons for more intuitive operation.
* Unaffected channel settings are preserved when the input channel selection changes.
* The new Meter Bridge tool behaves like a multi-channel version of the Sound Level Meter.
* Up and Down auto-scaling options have been added to the FFT Analyzer and Oscilloscope tools.
* Changes made to table rows can be applied to all rows in the FFT Analyzer and Oscilloscope control drawers.
* The Signal Generator tool now supports processing the output signals with up to three Audio Units plug-ins.
* The Signal Generator tool now supports streaming its output signals to WAVE or AIFF audio files.
* Verstion 2.1 includes numerous bug fixes and stability enhancements.
