Is your mix mono-safe? Check the phase.
Drop a track and get an instant verdict: overall phase correlation, the sections that collapse in mono, and a live goniometer while it plays. Club systems, phone speakers, and radio all fold to mono — know before they do.
Nothing is uploaded — your audio never leaves your device.
Colored zones under the wave mark sections where correlation drops — the parts most at risk when the mix folds to mono.
The scope draws left vs right at 45°: tall = mono-safe, round cloud = wide stereo, wide/flat = phase trouble. Flip "Listen in mono" to hear exactly what a club system hears.
Meters diagnose. Stems let you operate.
If the verdict says your low end cancels in mono, you need the parts, not just the picture. SongStrip separates any song into clean stems so you can fix the balance at the source. Sign up: 3 full packs free.
Frequently asked questions
What does phase correlation mean?
Correlation measures how similar the left and right channels are, from +1 (identical, fully mono-safe) through 0 (unrelated) to −1 (opposite polarity — cancels to silence in mono). Mixes usually live between +0.3 and +1; sustained negative readings mean trouble.
Why does mono compatibility matter?
Clubs, phone speakers, Bluetooth speakers, and many broadcast chains sum stereo to mono. Out-of-phase content — often from stereo wideners — simply disappears in that sum, taking your bass or hook with it.
What is a goniometer?
A phase scope: it plots left against right at 45°. A vertical line is mono, a wide cloud is spacious stereo, and a horizontal line means the channels oppose each other — the danger zone.
