Signal Generator

The powerful Signal Generator builds on the test signal synthesis capabilities of SignalSuite. Synthesize the following signals:

  • Periodic signals
    • Sinusoid
    • Variable-duty-cycle rectangular waveform
    • Triangle waveform
    • Sawtooth waveform
  • Broadband noise signals
    • Random noise (white and pink frequency weighting)
    • Maximum Length Sequence--MLS (white and pink frequency weighting)
    • Pseudorandom noise (white and pink frequency weighting)
  • Swept sine (chirp) signals
    • Linear sweeps (up, down, or both)
    • Log sweeps (up, down, or both)
    • Phase-locked cosine sweeps (up, down, or both)

The Signal Generator also supports the generator and effects types of Audio Unit plug-ins. The AU Generator tab contains controls for selecting generator plug-ins, including Apple's AUAudioFilePlayer for audio file playback within Electroacoustics Toolbox. The Signal Generators output channels can then be filtered or otherwise processed by up to three Audio Unit effects plug-ins, which can be accessed from the controls drawer at the bottom of the window.
