Post-processing for generated music. Default path is FFmpeg loudness normalization (fast, CPU-only). Escape hatches: AI vocal denoise for artifacts, stem separation for surgical edits. Both escape-hatch paths reuse tooling from the claude-video skill.

Loudness-normalize to the platform target in one ffmpeg call. This is the right answer 90% of the time — the generated audio is already clean; it just needs the level right.
# Two-pass loudnorm to -14 LUFS (Spotify/YouTube/Apple/TikTok all target this).
bash ~/.claude/skills/claude-music/scripts/music_export.sh spotify input.flac output.flac
See references/post-processing.md for the full platform × LUFS table and
the measure-then-apply two-pass recipe if you need manual control.
Use only when you hear artifacts in vocals (hissing, AI mush, robot tones). FFmpeg normalization won't help; you need DeepFilterNet3.
source ~/.video-skill/bin/activate
python3 ~/.claude/skills/claude-video/scripts/audio_enhance.py denoise \
input.flac --output output_clean.flac
Requires claude-video skill + DeepFilterNet3 weights. <1 GB VRAM.
Use only when you need to fix vocals/drums/bass/other separately, then remix. Not needed for normal enhancement.
source ~/.video-skill/bin/activate
python3 ~/.claude/skills/claude-video/scripts/audio_enhance.py separate \
input.flac --model htdemucs_ft --output-dir ./stems/
Produces vocals.wav, drums.wav, bass.wav, other.wav. ~7 GB VRAM.
Is the generated audio too quiet or too loud?
→ use the default path (loudnorm)
Do you hear specific vocal artifacts?
→ escape hatch 1 (denoise) THEN default path (loudnorm)
Do you need to fix one stem (e.g., reduce drums, retune vocal) before final mix?
→ escape hatch 2 (separate) → edit stem → remix → default path (loudnorm)
For platform-specific export (codec/bitrate/sample-rate), use
claude-music-export — it wraps music_export.sh with the right flags per
target (Spotify FLAC, YouTube MP3 320k, TikTok M4A 256k, etc.).

# claude-music-enhance — Audio Post-Processing
## Default path: loudness normalization (recommended first)
Loudness-normalize to the platform target in one ffmpeg call. This is the
right answer 90% of the time — the generated audio is already clean; it just
needs the level right.
```bash
# Two-pass loudnorm to -14 LUFS (Spotify/YouTube/Apple/TikTok all target this).
bash ~/.claude/skills/claude-music/scripts/music_export.sh spotify input.flac output.flac
```
See `references/post-processing.md` for the full platform × LUFS table and
the measure-then-apply two-pass recipe if you need manual control.
## Escape hatch 1 — AI vocal denoise (only if audible artifacts)
Use only when you hear artifacts in vocals (hissing, AI mush, robot tones).
FFmpeg normalization won't help; you need DeepFilterNet3.
```bash
source ~/.video-skill/bin/activate
python3 ~/.claude/skills/claude-video/scripts/audio_enhance.py denoise \
input.flac --output output_clean.flac
```
Requires `claude-video` skill + DeepFilterNet3 weights. <1 GB VRAM.
## Escape hatch 2 — stem separation (only if you need surgical edits)
Use only when you need to fix vocals/drums/bass/other separately, then remix.
Not needed for normal enhancement.
```bash
source ~/.video-skill/bin/activate
python3 ~/.claude/skills/claude-video/scripts/audio_enhance.py separate \
input.flac --model htdemucs_ft --output-dir ./stems/
```
Produces `vocals.wav`, `drums.wav`, `bass.wav`, `other.wav`. ~7 GB VRAM.
## Decision tree
```
Is the generated audio too quiet or too loud?
→ use the default path (loudnorm)
Do you hear specific vocal artifacts?
→ escape hatch 1 (denoise) THEN default path (loudnorm)
Do you need to fix one stem (e.g., reduce drums, retune vocal) before final mix?
→ escape hatch 2 (separate) → edit stem → remix → default path (loudnorm)
```
## Format conversion
For platform-specific export (codec/bitrate/sample-rate), use
`claude-music-export` — it wraps `music_export.sh` with the right flags per
target (Spotify FLAC, YouTube MP3 320k, TikTok M4A 256k, etc.).
## Scripts used here
- `scripts/music_export.sh` — default loudnorm + format conversion path.
- `~/.claude/skills/claude-video/scripts/audio_enhance.py` — AI denoise and
stem separation (external skill; must be installed separately).

Install targets
Codex install prompt
Install the "claude-music-enhance" agent skill from https://github.com/AgriciDaniel/claude-music/tree/main/skills/claude-music-enhance. Read its SKILL.md or equivalent instructions first, install only the files needed for this workspace, and summarize any required setup before using it. Skill purpose: Post-processing for generated music. Default path is FFmpeg loudness normalization (fast, CPU-only). Escape hatches: AI vocal denoise for artifacts, stem separation for surgical edits. Both escape-hatch paths reuse tooling from the claude-video skill. After the install attempt, report the result to https://www.openagentskill.com/api/agent/outcome with POST JSON {"event_id":"install_<unique-id>","skill_slug":"agricidaniel-claude-music-enhance","task":"Install claude-music-enhance","agent":"codex","outcome":"success","install_used":true}. Replace event_id with a unique value and outcome with success or failed. Report success only after the skill is installed and a minimal verification passes.
