SignalSuite 3.1.5

SignalSuite 3.1.5 is an updated tool of SignalSuite's tradition to offer 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.

Major Features:

1. Select any audio output device available in Mac OS X (version 10.4 or later)
2. Select any two output channels on multi-channel audio devices
3. Choose from all output signal formats supported by the current audio device
4. Invert polarity on either output channel
5. Generate any of the following signal types:
   • Sinusoid
   • Square Wave with arbitrary duty cycle
   • Triangle Wave
   • Sawtooth Wave
   • Random Noise (white or pink)
   • Maximum Length Sequence, or MLS (white or pink)
   • Pseudorandom Noise (white or pink), designed for a perfectly flat spectrum with corresponding FFT length
   • Swept Sine (Chirp) with linear or logarithmic frequency sweep
   • Optional Swept Cosine signal, phase-locked with Swept Sine
   • Any signals produced by Audio Unit generator plug-ins
6. Relative Phase adjustment between the two periodic signals
7. Independent amplitude adjustment, fine and coarse frequency controls, and pan for periodic signals
8. Choose upper and lower frequency limits, duration, sweep direction, and repeat of swept sine
9. Choose any combination of available signal types to be active simultaneously
10. Master Start/Pause control
11. Master Volume control
