Frequently Asked Questions
- What waveforms are supported?
- Sine, square, sawtooth, and triangle. Sine is the smoothest; square and sawtooth sound brighter and more buzzy.
- What frequency range can I use?
- Typically 20 Hz to 20,000 Hz (human hearing). Very low or very high values may be inaudible depending on your speakers.
- Is the WAV file created in the browser?
- Yes. The tone is generated with the Web Audio API and encoded as a WAV file entirely in your browser; nothing is sent to a server.
