How to use it
- Choose a waveform and set the frequency.
- Press Play. Start with a low volume, since pure tones can sound loud.
- Set a length and download a WAV of the tone.
Questions
Which waveform should I use?
Sine is the purest tone. Square, sawtooth and triangle have more harmonics and sound brighter.
Is it safe for speakers?
Keep the volume low, especially at very low and very high frequencies, and stop if you hear distortion.
