ToneGen is a sine wave generator, frequency generator and signal generator that lets you create audio test tones, sweeps or noise waveforms using your Mac OS X computer.

Features

• Generate sine wave, square wave, triangular waveform, saw tooth waveform, impulse, white noise and pink noise.
• Supports frequencies from 1Hz to 22kHz bandwidth (subject to sound card).
• Multiple simultaneous tones (1 to 16 tones can be created at the same time) (useful to create harmonics).
• Mono or separate stereo operation (ideal to create dual tones or 'beats').
• Tone Sweeps (Log or Linear).
