What it does
Audio Denoise is an agent skill from godot-fun/gai. Reduces background noise in a single audio file using FFmpeg afftdn. Use when the user wants audio denoise, noise reduction, hiss removal, room noise cleanup, or SFX/voice cleanup before normalization.
Its SKILL.md is about 470 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Media & Creative, covering Video production and Database schema design. It works with FFmpeg. The repository describes itself as: A lightweight AI agent and skill workflow framework built with Godot. The licence is MIT.
When your agent uses it
- The user wants audio denoise
- Noise reduction
- Room noise cleanup
- SFX/voice cleanup before normalization
Example prompts
- “Use the audio-denoise skill to reduce background noise in a single audio file using FFmpeg afftdn”
- “/audio-denoise”
Requirements
- Python 3
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Use the bundled script, not hand-written afftdn filters.
- Default is light denoise — do not raise --nr unless the user asks; heavy denoise dulls transients.
- Missing Python/FFmpeg → populate .dependency/ per skill-dependency-manager, retry same command.
- Do not copy, move, or replace the source with denoised output — tell the user where audio-denoise/ files are; they swap assets manually…
What it can do on your machine
Read from SKILL.md and the folder at commit aff659b. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
python
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Audio Denoise loads about 465 tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 149 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- Reduces background noise in a single audio file using FFmpeg afftdn. Use when the user wants audio denoise, noise reduction, hiss removal, room noise cleanup, or SFX/voice cleanup before normalization.
Audio Denoise
Reduce background noise via FFmpeg afftdn.
Rules
When this skill applies, read and follow skill-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.wavDefaults
| Setting | Default | Notes |
|---|---|---|
| Denoise | afftdn | nr=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 8Originals 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 hand-written
afftdnfilters. - Default is light denoise — do not raise
--nrunless the user asks; heavy denoise dulls transients. - Missing Python/FFmpeg → populate
.dependency/per skill-dependency-manager, retry same command. - Do not copy, move, or replace the source with denoised output — tell the user where
