Draw the shape of a recording as a picture.
The waveform image tool works on our server: the recording is sent to us, changed there and sent back as a file.
Is it free?
Yes. Every audio tool here is free, with a fair-use limit per address so the shared servers stay fast for everyone.
How long is my recording kept?
An hour for a visitor, a day for a signed-in person. Then the file is gone.
What does it accept?
MP3, WAV, FLAC, OGG, M4A, AAC, Opus, WMA, AIFF and the video formats that carry audio.
Input: width, height, color, bgColor. Needs a signed-in browser session or a token with tools.tool.run.
