About

Audio Denoise

Reduce background noise via FFmpeg afftdn. Optionally repair clipped peaks with adeclip.

Rules

When this skill applies, read and follow [skill-dependency-manager](../../rules/skill-dependency-manager.md) — run scripts as documented, install missing tools into .dependency/.

Quick Start

Default: denoise only (afftdn), output to denoised/:

.dependency/python/python .cursor/skills/audio-denoise/scripts/denoise.py path/to/audio_or_folder

Clipped source (de-clip then denoise):

.dependency/python/python .cursor/skills/audio-denoise/scripts/denoise.py path/to/audio.wav --declip

De-clip only:

.dependency/python/python .cursor/skills/audio-denoise/scripts/denoise.py path/to/audio.wav --declip-only

Defaults

| Setting | Default | Notes | |---------|---------|-------| | Denoise | On (afftdn) | nr=10 dB, nf=-25 dB — conservative for SFX | | De-clip | Off | Pass --declip or --declip-only when needed |

Common Flags

--declip · --declip-only · --no-denoise · --nr · --nf · -r · -o / --output-dir · --dry-run · --overwrite

.dependency/python/python .cursor/skills/audio-denoise/scripts/denoise.py Audio/SFX -r --dry-run
.dependency/python/python .cursor/skills/audio-denoise/scripts/denoise.py Audio/Voice -nr 8 --declip

Originals are never modified. Supported: .wav, .mp3, .ogg, .flac, .aac, .m4a, .wma.

Agent Notes

  1. Use the bundled script, not hand-written afftdn / adeclip filters.
  2. Default is light denoise — do not raise --nr unless the user asks; heavy denoise dulls transients.
  3. Use --declip only when peaks are visibly or audibly clipped; skip for clean recordings.
  4. Missing Python/FFmpeg → populate .dependency/ per skill-dependency-manager, retry same command.
  5. Do not copy, move, or replace the source with denoised output — tell the user where denoised/ files are; they swap assets manually when ready.
  6. FFmpeg filter details: [reference.md](reference.md)
