Normalization is not compression; leveling is not normalization
Normalization changes gain toward a target; leveling changes level relationships over time; compression shapes dynamics through a detector and curve.
Diagnosis
- Ask whether the problem is absolute level, moment-to-moment level or dynamic shape.
- Level-match before judging processors.
- Inspect what changes when bypassing.
Decision
- Use gain for absolute offsets.
- Use automation or leveling for phrase balance.
- Use compression when the dynamic behavior itself needs shaping.
Measurement boundary
Correct terminology makes troubleshooting faster because each control solves a different class of problem.
Common failure: A louder processed signal can win an A/B even when the processing is worse.
