01Overview

Blue Cat's Oscilloscope Multi is aimed at producers and engineers who need to see how audio signals line up. It shows the waveforms of multiple tracks at once, so you can compare levels, timing and shape side by side. Its dual-channel XY phasescope view, also called a Lissajous display, helps reveal phase cancellation and mono compatibility problems, whether across tracks or within an effect chain.

03In depth

Multi-track waveform comparison and measurement

The plugin renders several audio tracks on the same screen, which makes it easy to compare their waveforms directly. Waveforms can be displayed in loop, flow or trigger modes, and a histogram view shows how values are distributed across the waveform, including an idea of average peak level.

Zoom is animated across all displays, and precise measurement tools let you examine details closely. Latency compensation can align waveforms from different sources, and you can save curves, name each one and use them for A/B comparison.

Phase checking, channel modes and workflow controls

The dual-channel XY phasescope shows phase relationships between two signals, useful for detecting phase cancellation and mono compatibility issues. Left-Right and Mid-Side operation modes are both available.

For workflow, the interface can be skinned and customized, with opacity control for transparency. Undo/Redo is included, and presets can be imported and exported in a host-independent format. Full MIDI control and automation are supported, with MIDI Learn and silent, zipper-free parameter updates.
