About

Audio Trim

Remove leading/trailing silence via FFmpeg silenceremove.

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: threshold -50 dB, both sides, output to trimmed/:

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

Thresholds

| Asset | Threshold | |-------|-----------| | UI / SFX / voice | -50 dB (default) | | Clipped attack / noisy room | -40 to -45 dB | | Ambience / loops | -60 dB or skip |

Common Flags

-t (threshold dB) · --no-start · --no-end · -r · -o / --output-dir · --dry-run · --overwrite

.dependency/python/python .cursor/skills/audio-trim/scripts/trim.py Audio/SFX -t -50 --no-end -r --dry-run

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

Agent Notes

  1. Use the bundled script, not ad-hoc -ss/-to.
  2. Looping BGM — avoid batch end-trim; can break loop seams.
  3. Attack or reverb cut off → raise -t or use --no-end.
  4. FFmpeg filter details: [reference.md](reference.md)
