Tone Generator
Generate precise audio tones. Choose frequency, waveform shape, and level. Play in real-time or download as WAV.
What this tool tells you
What it does
Use this when you need a controlled sine, square, triangle, or sawtooth tone for a listening, routing, or equipment check.
How to use it
Choose a frequency, waveform, and digital level, then play the tone or generate a WAV file for later use.
How to interpret it
The level control is dBFS, a digital signal value, not acoustic SPL. Start low and raise your playback level carefully because the actual loudness depends on your equipment and volume setting.
