audio-volume-adjust skillA
audio-volume-adjust is agent-read markdown (skill) from godot-fun/godot-agent: Adjusts audio file volume up or down using FFmpeg. Use when the user wants to change volume, boost or reduce loudness, attenuate or amplify SFX/UI/BGM, apply dB gain, raise/lower clip levels, or batch-adjust audio amplitude..
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 Volume Adjust Apply a uniform **gain change** across the full clip — no fade, no loudness targeting. Negative dB reduces level; positive dB increases it. ## 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 Reduce by 6 dB (~half amplitude), output to `<audio-dir>/audio-volume-adjust/<audio-name>`: ```bash .dependency/python/python .ai/audio-volume-adjust/adjust.py --audio path/to/audio.wav --volume -6 ``` Example: `audio/sfx/tank/tank_move.wav` → `audio/sfx/tank/audio-volume-adjust/tank_move.wav` Boost by 3 dB: ```bash .dependency/python/python .ai/audio-volume-adjust/adjust.py --audio audio/sfx.wav --volume 3 ``` ## Adjustment Guidelines | Goal | `--volume` (dB) | |------|-----------------| | Slight reduction | -3 | | Half amplitude | -6 | | Noticeably quieter | -9 to -12 | | Background / distant | -15 to -20 | | Slight boost | +3 | | Noticeably louder | +6 | ## Common Flags `--audio` · `--volume` · `-o` / `--output` ```bash .dependency/python/python .ai/audio-volume-adjust/adjust.py --audio audio/sfx.wav --volume -9 …

How to install
mdr add godot-fun/godot-agent/audio-volume-adjust@git:20260918.a3d4acfmdr add godot-fun/godot-agent/audio-volume-adjust@sha256:5b4cfd850d060064Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
