TL;DR — 40-second answer
Compress vocals in Logic Pro with serial compression across three jobs. A fast 1176-style stage catches peaks, a slower LA-2A-style opto stage smooths the phrase, and an aggressive third stage is only added if the production benefits. One compressor cannot do all three.
Fast 1176-style compressor catches inconsistent peaks first.
LA-2A-style opto stage levels the main vocal body.
Stock alternative: Logic Compressor in Vintage FET mode + Vintage Opto mode.
Add a de-harshing stage after grit if the upper mids get sharp — do not compress harder to fix harshness.
Overview
Serial Compression Logic
Use serial compression rather than one overworked compressor. Fast peak control first, smoother leveling second, and aggressive character only if the production asks for it.
The common failure is using one compressor and asking it to catch peaks, smooth phrasing, and add character simultaneously. Serial stages handle each job cleanly.
Step by Step
Processing Order
A fast FET stage should catch peaks, not flatten the phrase.
An opto-style second stage should make the performance feel settled, not smaller.
If the vocal gets harsh after compression, fix the harshness rather than backing off all control.

Avoid These
Common Mistakes
Trying to get all vocal control from one compressor.
Using fast attack and fast release on every stage by default.
Backing off compression when the real issue is harshness, not gain reduction.
