We split this skill into the rules it gives an agent

2 rules. About 0 are common, 0 are distinctive, and 2 are very specific to this project.

    Many files like this have a rule of this kind.

    This author's own choices. Worth a look.

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Very specific
  1. Very specific:

    When this skill applies, read and follow dependency-manager — run scripts as documented, install missing tools into .dependency/.

  2. Very specific:

    Use the bundled script, not hand-written afftdn filters.

    line 41

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Audio Denoise

Reduce background noise via FFmpeg afftdn.

Rules

When this skill applies, read and follow dependency-manager — run scripts as documented, install missing tools into .dependency/.

Quick Start

Denoise a single audio file, output to <audio-dir>/audio-denoise/<audio-name>:

.dependency/python/python .ai/audio-denoise/denoise.py --audio path/to/audio.wav

Defaults

SettingDefaultNotes
Denoiseafftdnnr=10 dB, nf=-25 dB — conservative for SFX

Common Flags

--audio · --nr · --nf · --output

.dependency/python/python .ai/audio-denoise/denoise.py --audio Audio/SFX/click.wav
.dependency/python/python .ai/audio-denoise/denoise.py --audio Audio/Voice/line.wav --nr 8

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

  1. Use the bundled script, not hand-written afftdn filters.
  2. Default is light denoise — do not raise --nr unless the user asks; heavy denoise dulls transients.
  3. Missing Python/FFmpeg → populate .dependency/ per dependency-manager, retry same command.
  4. Do not copy, move, or replace the source with denoised output — tell the user where audio-denoise/ files are; they swap assets manually when ready.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
