How is the waveform computed?

The audio is split into equal time buckets and the peak (max absolute amplitude) in each bucket is plotted — a standard downsampled waveform view, the same approach audio editors use for a zoomed-out overview.

Can I export the waveform image?

The waveform is rendered for viewing on this page; there is no separate image export for it yet.

Does this tool upload my audio anywhere?

No — the waveform is generated entirely in your browser with the Web Audio API.
