Test Tone Download
Export reference tones as WAV files without playing them live first.
Render offline — no server upload. 44.1 kHz, 16-bit.
What this tool does
Configure any test tone — frequency, waveform, volume, and duration — then download it as a standard WAV file. Ideal for calibration clips, test playlists, education demos, and offline reference tones.
How export works
When you click Download WAV, the browser builds the file using OfflineAudioContext. The same synthesis math as live playback ensures what you hear in Preview matches the exported file.
Tips for best results
Shorter files render faster. Use sine for pure references; square or sawtooth when you need harmonic content. Share settings via the link button — frequency and waveform encode in the URL hash.
How to use
Adjust settings
Use sliders and controls to set frequency, volume, and waveform. Changes apply in real time.
Export or share
Download a WAV file or copy a share link. All processing stays on your device.
