Mastering Compression Cheat Sheet - The Four Topologies

The compressor cheat sheet I wish someone had given me when I started mixing. Four topologies — Optical, FET, VCA, Variable-Mu — broken down by how they actually work, what they sound like, and when to reach for each one. Side-by-side response curves so you can see why FET is "fast" and Optical is "slow" instead of just being told. Includes: - Audio-path schematics for each topology (LDR cell, transistor, VCA, vacuum tube) - Sonic character snapshot per topology - Best uses with instrument ico
