Signal chain

Fine-tune the processor.

These parameters shape the next render. The original audio is always preserved.

Bass & equalization

Weight, emphasis and space for the mix.

Dynamics

Punch scales transient lift; compression follows the selected character.

Saturation

Warmth adds harmonics to the bass band.

Output & limiting

The sample-peak ceiling also applies to distorted modes.
Import from a link

Open a media file.

Use a direct HTTPS link to an audio or video file. The host must allow browser access. Platform watch pages and protected streams cannot be imported directly.

Signal measurements

Made for listening.

Import → analyze → render → compare → export. All processing happens in this browser. Video imports use the audio track where the browser supports the codec.

Navigate

Click or drag the waveform to seek. Zoom with + / − and pan with the overview. Fit returns to the whole track.

Compare

Switch A / B at the same playback position. Level match adjusts playback only. Changed settings require a new render.

Shortcuts

Space: play / pause · A / B: compare · + / −: waveform zoom · 0: fit · ⌘ / Ctrl O: import.

Engine limits

50 MB, 8 minutes or 24 million decoded channel samples. RMS level and sample peaks are measured; no LUFS or true-peak claims.
