Mix Note 104 / Mastering New

The side channel can hide a problem

A stereo master feels fine until mono playback loses a key instrument.

The move

Check mono and audition sides to locate phase-dependent content, then fix the responsible source where possible.

Do this
  1. Compare stereo and mono playback.
  2. Audition sides to find disappearing content.
  3. Fix the responsible source where possible.

Listen for this.

The lead and rhythmic foundation should remain useful in mono.

Know when to back off.

A correlation meter is a clue, not a universal pass/fail judge.

Match loudness when you compare. If the original serves the song better, undo the change.
