How to use the audio waveform generator

  1. Choose an MP3, WAV, M4A or other audio file.
  2. Pick a style (bars, line or mirror), colours and size; the preview updates instantly.
  3. Download the waveform as a PNG — transparent if you like.

Waveform images look great as podcast cover art, on posters and wall prints of a special song or a baby’s first word, in social posts announcing a new track, and as a progress bar design in apps. The audio is decoded only on your device.
