FAQ
How is the waveform calculated?
The audio track is split into 200 equal segments, and the loudest (peak) sample in each segment becomes the height of one bar — a standard way to visualize a waveform without rendering every individual sample.
What is the difference between the three styles?
"Bars" draws upward from the bottom, "Mirrored bars" draws symmetric bars around the center line, and "Line" connects the peaks into a continuous waveform line.
What is this useful for?
Cover art for a podcast episode or song, a visual thumbnail for a video, or a quick visual reference for an audio file's dynamics.
Is my audio uploaded anywhere?
No — the analysis and drawing happen entirely in your browser using the Web Audio API and Canvas. Nothing is sent to a server.
How we compare
| Feature | Online Tool Store | DAW screenshot export | Podcast platform auto-generated art |
|---|---|---|---|
| Custom colors and style | ✓ | Locked to the DAW's theme | Usually one fixed style |
| No DAW or account needed | ✓ | Requires audio production software | Tied to one platform |
For a quick, on-brand waveform graphic without opening a DAW or being locked into one platform's auto-generated look, this is faster and more flexible.
