audio-fade skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, same audit grade.
audio-fade is agent-read markdown (skill) from godot-fun/gai: Applies fade-in and fade-out at the start and end of a single audio file using FFmpeg. Use when the user wants audio fade, fade in/out, smooth attack/release, crossfade prep, SFX envelope shaping, or mentions afade..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Audio Fade Apply **fade-in** at the start and **fade-out** at the end without changing clip length. ## Rules When this skill applies, read and follow [skill-dependency-manager](../skill-dependency-manager.md) — run scripts as documented, install missing tools into `.dependency/`. ## Quick Start Default: **1 s** fade-in and fade-out, output to `<audio-dir>/audio-fade/<audio-name>`: ```bash .dependency/python/python .ai/audio-fade/fade.py --audio path/to/audio.wav ``` Fade-in only (keep full end level): ```bash .dependency/python/python .ai/audio-fade/fade.py --audio path/to/audio.wav --no-fade-out ``` Custom durations (seconds): ```bash .dependency/python/python .ai/audio-fade/fade.py --audio audio/sfx.wav -fi 0.05 -fo 0.15 ``` ## Duration Guidelines | Asset | Fade-in | Fade-out | |-------|---------|----------| | UI clicks / ticks | 0.01–0.05 s | 0.02–0.08 s | | Impacts / weapons | 0.02–0.08 s | 0.05–0.15 s | | Voice lines | 0.05–0.15 s | 0.1–0.25 s | | Ambience beds | 0.3–1.0 s | 0.5–2.0 s | | BGM one-shots | 0.2–0.5 s | 0.3–1.0 s | Fade-in + fade-out must stay **shorter than file duration**. Very short clips need smaller values. ## Common Flags …

Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
