Stereo field analysis: width, phase & mono safety
Stereo field analysis looks at how your mix uses the left-right image — how wide it is, whether the sides stay in phase, and whether the low end collapses cleanly to mono. Get it wrong and the mix hollows out on a phone or loses its sub in a club. Unveil measures stereo width, phase correlation, and mid/side balance, and flags low-end that's too wide to translate.
What you get
- Stereo width and mid/side ratio — how much of your energy is in the sides vs the center.
- Phase correlation: why sustained negative correlation destroys your mix in mono.
- Low-end mono compatibility — keeping sub and bass mono below ~80–120 Hz for club and phone translation.
- A free stereo readout that tells you if you're too narrow, too wide, or phase-risky.
Questions
What is phase correlation?
A −1 to +1 measure of how similar your left and right channels are. Near +1 is mono-safe; sustained negative values mean parts of the mix cancel out when summed to mono.
Should bass be in mono?
Generally yes below ~80–120 Hz. Wide stereo bass causes phase cancellation on club systems and mono playback, robbing the low end of punch.
