Waveform Generator
Render an audio file as a waveform image.
This free waveform generator renders any audio file as a clean waveform image. Load an MP3, WAV, OGG or M4A and control everything: bars, filled or a single line; a solid color or a gradient between two colors; exact width and height with social presets; bar count and gap; a mirrored (center-line) look; and a transparent background. Export a crisp PNG at up to 3× for retina and print, or a scalable SVG you can edit in any vector tool. The audio is decoded with the Web Audio API.
