See your stereo image
Goniometer, correlation, balance and levels, all at once. A stereo and phase analyzer for iPhone and iPad.

The classic polar view
Where every sound sits, from left to right, and how wide.
X/Y draws the shape of the stereo image; polar folds it into a half circle, from left to right. Both views work upright and sideways.

Make it yours
Trail, zoom and four trace colors, a tap away.
A short or a long trail, auto or fixed zoom, and the trace in the color that reads best on your screen. Tap the scope to reset the zoom.

Right in your session
An AUv3 for GarageBand, Logic Pro, AUM and every host that loads one.
Load it on a track or on the master. It takes whatever view the host gives it, from a slim strip under the tracks to a whole panel.

Also on its own
Plug in a USB audio interface and watch any stereo source, no host needed.
A console's mix bus, a synth, a turntable. The built-in microphone is mono, and the app tells you when its input is.

Folded or open
iPhone, iPad and iPhone Duo, each with its own layout.
Upright or sideways, on the outer screen or the inner one, the meters rearrange to the shape they are given.
