From grimoire
Places audio elements in the stereo field to create width, depth, and separation while ensuring mono compatibility. Covers panning, Haas effect, mid-side processing, and depth via reverb pre-delay.

Place audio elements in the stereo field to create width, depth, and separation without sacrificing mono compatibility.
Adopted by: David Gibson's three-dimensional mix visualization is taught in audio engineering programs worldwide; mastering engineers universally require mono-compatible mixes Impact: Gibson's "The Art of Mixing" documents that spatial placement is perceived as emotional distance — elements panned center feel more intimate; wide elements feel distant or environmental. This is not metaphor; it is perceptual psychology.
Why best: A flat, center-panned mix is fatiguing and lacks dimension. Strategic stereo field design creates the auditory illusion of a physical space — instruments in specific locations, depth from front to back. However, every width decision must be verified in mono because streaming services, phone speakers, and many club systems sum to mono, collapsing unchecked stereo into phase cancellation artifacts.
Pop mix stereo layout: Center (0): kick, snare, bass, lead vocal. L15/R15: acoustic guitar doubles, piano. L40/R40: electric guitar layers, synth pads. L60/R60: hi-hats (alternating takes), percussion fills. L100/R100: ambience reverb tail only (not dry signal). Depth: lead vocal closest (short reverb, loud). Background vocals behind (more reverb, -3dB). Room reverb on drums farthest back.
npx claudepluginhub jeffreytse/grimoire --plugin grimoireProfessional mixing methodology for audio engineering. Guides through pre-mix analysis, phase checking, gain staging, EQ decisions, compression selection, spatial processing, and automation. Encodes the decision-making process of a senior mix engineer backed by Phantom MCP measurement tools. Use this skill whenever the user wants to mix stems or tracks, balance a mix, make EQ or compression decisions, set up signal chains, choose compressor types, solve frequency conflicts between instruments, set up spatial processing (reverb, delay, panning), automate volume or effects, or compare their mix against a reference. Also use when the user mentions muddy mixes, harsh frequencies, buried vocals, kick/bass conflicts, or any mixing problem -- even if they don't say "mix" explicitly.
Determines optimal audio processing order for plugins and hardware to maximize headroom and sound quality, covering gain staging, EQ, compression, and time-based effects.
Polishes raw Suno audio by processing per-stem WAVs with targeted cleanup, EQ, and compression, then remixing into a polished stereo WAV ready for mastering.
