What is audio-denoise?

An audio tool that reduces steady background noise such as hiss or room noise in a single file. It uses FFmpeg's noise-reduction filter and leaves the original file unchanged.

Use it to clean voice recordings, sound effects, or other supported audio files before further processing such as volume adjustment.

It makes speech and sound effects cleaner when recordings contain unwanted background sound. Light processing can reduce noise while preserving the main audio.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00048	$0.00500
Opus 5.5	$0.00019	$0.00200
Sonnet 5.5	$0.00010	$0.00100
Haiku 4.5	$0.00005	$0.00050

Security

Grade A, and why

audio-denoise scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

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.wav

Defaults

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 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

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 when ready.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
