Blue Cat's Oscilloscope Multi is a unique multiple tracks real time waveform renderer and comparator: it lets you visualize the content of several audio tracks on the same screen and compare them thanks to its X-Y view.
The plugin offers stereo or mid-side channels waveform extraction as well as several synchronization modes. The zooming and precise measurement capabilities let you analyze the waveforms in details, and the XY phase scope view will help you track phase issues within an effect chain or while recording with multiple microphones.
The additional histogram display complements the toolset to check the distribution of the values in the waveform and get an idea of the average peak level.
The four memory slots let you store any waveform in memory: it helps you make comparisons between several setups or portions of your audio project very easily.
