Remove leading/trailing silence via FFmpeg silenceremove.
Rules
When this skill applies, read and follow skill-dependency-manager — run scripts as documented, install missing tools into .dependency/.
Quick Start
Default: threshold -50 dB, both sides, output to <audio-dir>/audio-trim/<audio-name>:
.dependency/python/python .ai/audio-trim/trim.py --audio path/to/audio.wav
Custom threshold:
.dependency/python/python .ai/audio-trim/trim.py --audio audio/sfx.wav -t -45
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
--audio · -t / --threshold · -o / --output
.dependency/python/python .ai/audio-trim/trim.py --audio audio/sfx.wav -t -50
Originals are never modified. Input must be a single audio file (--audio), not a directory. Supported: .wav, .mp3, .ogg, .flac, .aac, .m4a, .wma.
Agent Notes
- Use the bundled script, not ad-hoc
-ss/-to. - Looping BGM — avoid end-trim; can break loop seams. Skip this skill or trim manually.
- Attack or reverb cut off → raise
-t(e.g.-45or-40). - FFmpeg filter details: reference.md
