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.
Version 3 includes various other improvements over previous versions.
SignalScope 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.

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.
* 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.
* Verstion 2.1 includes numerous bug fixes and stability enhancements.
