HOW PRODUCERS USE A PHASE METER

Stereo Width
Without Collapse.

A phase meter helps you catch stereo problems before they turn into weak mono playback, hollow vocals, thin bass, or disappearing effects.

01

Mono Safety

Negative correlation can mean parts of the mix may cancel when played in mono.

02

Low End

Kick, 808, bass, and sub information should usually stay highly positive and centered.

03

Stereo Effects

Wide reverbs, delays, chorus, and widening plugins can create phase issues fast.

04

Master Bus

Check the final mix before export so wide mastering moves do not weaken translation.
