Wide chorus that still survives mono
Chorus width becomes fragile when delay and modulation relationships create strong cancellation in the mono sum.
Diagnosis
- Compare wet-only and full mix in mono.
- Watch low-frequency modulation separately from upper-band width.
- Check correlation during the densest section.
Decision
- Keep the center anchor stable.
- Move more width to bands that tolerate it.
- Reduce modulation depth or opposing delay when mono loss is audible.
Measurement boundary
The right compromise is perceptual: width that adds value in stereo without removing essential information in mono.
Common failure: A mono-safe preset is not safe for every source because source phase relationships also matter.
