Every sample where you left it.

Open a two-hour recording and zoom from the whole file down to a single sample. Sources are never touched.

Cut anywhere. Hear no click.

Every edit lands on a sample, finds a zero crossing, and gets a micro-fade. Undo all of it, as far back as you like.

See what you can't hear.

Flip to the spectrogram. Draw around a cough, a phone buzz or a chair creak and paint it out.

Finish at −23.4 LUFS.

Master to your target with a true-peak ceiling, then compare at matched loudness so louder never wins by default.

Real binaural audio, moving around your head.

Put on headphones. The sound follows the dot.

±0.1 LULoudness accuracy against the EBU conformance signals, so −14 LUFS means −14 LUFS.

−100 dBFSMaximum difference between what you preview and what you export. Same engine, same output.

±3 centsPitch accuracy across a full octave of shifting up or down.

1 sampleEdit precision. Cuts, fades and automation resolve to samples, never to pixels.
