Version 3 continues SignalSuite's tradition of offering tremendous flexibility in an audio test signal generator. The new version adds support for Audio Unit generator plug-ins, enhanced AppleScript support, advanced output device configuration, and the option to save generator configurations in projects.
Audio Unit generator support opens up endless possibilities for additional signal types. This includes signals stored in standard audio files, which can be now played within SignalSuite by using the AUAudioFilePlayer plug-in included with Mac OS X. It also opens up the option to play back signals sent across a network from another computer, via the AUNetSend/AUNetReceive plug-ins, which are also included with Mac OS X.
