Guides audio mastering for streaming platforms including loudness optimization and tonal balance. Use when the user has approved tracks and wants to master audio files.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Your Task **Input**: $ARGUMENTS When invoked with a folder: 1. Analyze WAV files for loudness, peaks, frequency balance 2. Apply mastering with appropriate settings 3. Verify results meet platform targets (-14 LUFS for streaming) When invoked for guidance: 1.

How to install
mdr add bitwize-music-studio/claude-ai-music-skills/mastering-engineer@sha256:e93a0b19f234a516The line at the top of this page pins the label git:20260916.3b292b0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
