Tone Generator

Generate a sine, triangle or band-limited saw/square test tone with precise frequency and duration.

How to use

Set frequency, duration, waveform and level. Generate audio, start at a low listening volume and export WAV.

Know the limits

Continuous tones can sound loud. Saw and square waves use harmonic synthesis limited below Nyquist.
