mastering-prep skillA
mastering-prep is agent-read markdown (skill) from glincker/ableton-skills: Use when the user is finishing a track and wants to check it's ready to send to a mastering engineer or for self-mastering. Audits headroom, peak levels, mono compatibility, frequency balance, LUFS. Examples - "is this ready to master?", "audit my mix before export", "check my levels"..
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
# Mastering Prep Pre-master audit. Confirm the mix is in a clean state for either external mastering or self-mastering. Does NOT apply final mastering — that's a separate workflow with explicit user intent. ## Workflow ### 1. Read the master bus - `get_track_info` for master - `get_device_parameters` for any plugins on master - Check current peak level, RMS, LUFS if available ### 2. Run the audit checklist For each item, mark ✅ pass or ❌ fail with the specific reading: | Check | Target | What to look for | | --- | --- | --- | | **Peak level** | -3 to -6 dB | Master should have headroom — never above -1 dB | | **No master limiter active for export-to-mastering** | Off | Mastering engineer wants raw mix; remove limiter from master | | **No master compressor over 2 dB GR** | <2 dB | Heavy mastering compression on a pre-master is destructive | | **LUFS integrated** | -16 to -20 LUFS for pre-master | Too loud = no headroom for mastering | | **Mono compatibility** | All elements audible in mono | Toggle Utility's mono switch — verify nothing disappears | | **Phase coherence** | Above 0.0 (positive) | Use Spectrum or Stereo & Phase — dips below 0 = destructive cancellation | …
