Choose an audio fileThis is dynamic-range compression using the browser Web Audio compressor. It is not file-size compression and does not claim mastering-grade analog emulation.

Verify the source before trusting the render

Decode locally, confirm sample rate, channels, duration and level evidence, then apply the transformation. Keep codec, browser decode and export-format limits explicit.

Codec and measurement boundaries

Browser decoding differs across Safari, Chrome, Firefox, iOS, and Android. Rendered edits are exported as WAV unless a tool explicitly states another supported container. Loudness analysis is a practical BS.1770-style estimate rather than a certified meter, and sample clipping checks do not replace true-peak oversampling.

Dynamics output needs headroom review

Threshold, ratio, knee, attack, release, and make-up gain are treated as render parameters. Changing them invalidates the previous download until the compressor is rendered again.
