DIAGNOSIS

How to verify it

  1. Compare before and after at matched loudness in the full mix.

PROCEDURE

CONDITIONS AND EXCEPTIONS

When the answer changes

Conditions: The stated symptom or goal is genuinely audible in context.

Exceptions: Different sources, genres, arrangements, and playback systems can require a different decision.

COMMON FAILURE MODES

What usually goes wrong

  • Using a setting because it is common rather than because it solves the audible problem.
  • Judging the louder result as better without level matching.

EVIDENCE AND SOURCES

How certain is this?

Confidence: High. Context-dependent production guidance.

No external source is asserted for this draft yet. Publication requires technical review and sources where factual history or named-artist claims are involved.

Method boundary: Treat ranges as starting points and verify the result in context at matched loudness.
