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.
Frequently Asked Questions
- What waveforms are available?
- Sine, square, triangle, and sawtooth waveforms are available. Sine is a pure tone, while the others contain harmonics useful for testing audio equipment.
- Can I download the generated tone?
- Yes. Click "Generate WAV" to create a downloadable WAV file of your configured tone.
- Is the level setting dBFS or dB SPL?
- The control sets digital level in dBFS, not acoustic sound pressure level. Actual SPL depends on your device, amplifier, speakers or headphones, and volume control. Start low when testing.
