FAQ

About audio waveform

Can I use a video as the input?

Yes. The first audio track of the video is drawn. Inputs with no audio stream are rejected with a typed error.

Which format keeps the transparent background?

PNG and WebP keep transparency; JPEG renders the waveform on a black background.
