✅ Done — your audiogram image
How it works
- Step 1 — Upload an audio file (MP3, WAV, M4A, OGG). It is decoded locally with the Web Audio API.
- Step 2 — The real waveform peaks are sampled and drawn as bars, a line, or mirrored bars, with your title and colors.
- Step 3 — Export a full-size PNG image and post it with a link to the full audio.
Note: this tool exports a static audiogram image (not an animated video). For an animated waveform video, pair the image with your audio in any video editor.

- Musicians — tease a track with a branded waveform image.
