Clean up
Clean recordings and separate voices from music. Noise reduction, hum and DC offset removal, noise gates and vocal removal all run locally; the AI model for vocal separation is downloaded from this site once and then cached.
- Noise ReductionRemove background noise and hiss from voice recordings with an on-device speech denoiser, or learn a steady noise profile. Nothing is uploaded.
- Clean Up Voice RecordingClean up a voice memo, interview or podcast in one pass: low-cut, noise reduction, loudness to -16 LUFS and silence trimmed. Runs on your device.
- Noise GateApply a noise gate that mutes audio below a threshold, with attack, hold and release. Useful for cutting hiss between words. Runs in your browser.
- Remove Hum (50/60 Hz)Remove 50 Hz or 60 Hz mains hum and its harmonics with narrow notch filters. Pick the frequency, the number of harmonics and the width, then export.
- Remove DC OffsetMeasure and remove DC offset so the waveform is centered on zero. It frees headroom and fixes clicks at cuts. See the offset before and after.
- Vocal RemoverRemove vocals from a song to make a karaoke or instrumental track with on-device AI. One model download, then it is cached in your browser.
- Isolate VocalsExtract the vocals from a song as an acapella using on-device AI. Download vocals, drums, bass and other as separate files. No upload.
