What The Stereo
Image Is Doing.
This section explains whether your audio is mono-safe, too wide, phasey, imbalanced, or at risk of losing elements in mono.
Phase and mono compatibility notes will appear here after analysis.
What Each Number
Means.
TPH explains correlation, mid/side energy, stereo width, and mono compatibility in plain language.
Correlation compares the left and right channels. Positive values are usually safer; negative values can mean phase cancellation.
Mono compatibility tells you how well the audio will survive when played on mono speakers, phones, clubs, or certain playback systems.
Mid is the center information. Side is the stereo width. Too much side energy can create width but may hurt mono translation.
