Slide or type any frequency from 1 Hz to 22 kHz and hear it straight away. Jump an octave up or down, pick a common frequency such as 50 Hz, 440 Hz or 1 kHz, and see the nearest musical note.
Choose a sine, square, triangle or sawtooth wave, send it to the left or right speaker, and save the tone or a sweep between two frequencies as a WAV file.
What you get
- 1 Hz to 22 kHz, to two decimals
- Sine, square, triangle and sawtooth
- Shows the nearest note and cents
- Left, right or both speakers
- Frequency sweeps
- Save as WAV or MP3
How to play a tone
- Open the tone generator.

Tip: Start quiet. High tones can sound much louder than you expect and can damage hearing and speakers.
