Blue Cat Audio StereoScope Pro

What Blue Cat StereoScope Pro Is For

Blue Cat StereoScope Pro is a professional analysis plug-in designed to monitor, understand, and master the stereo image of an audio signal. It is suited for both mixing and mastering: checking stereo width, panorama coherence, bass stability in the center, and quickly spotting risks of phase cancellation or mono energy loss. It is a valuable tool for comparing multiple takes, validating an effects chain, or bringing your mix closer to a reference by precisely observing a track's "stereo signature."

Main Features

Three visualization modes for immediate reading

Adapt the display to your task: stereo image for direct reading of the stereo field, stereogram to observe evolution over time (in 2D or 3D), and an output parameters view that translates the stereo image into explicit values (position and width). This approach multiplies analysis angles and speeds up decisions, especially when correcting panoramas, widening effects, or reverb/delay ambiances.

3D "waterfall" view: the stereo image over time, in depth

The 3D waterfall mode allows detailed visualization of the stereo field's evolution with a solid or wireframe surface, and full 3D control. Very useful for spotting intermittent phenomena: overly aggressive widening on certain passages, stereo instabilities on choirs, or width changes linked to automation.

Precise measurements, animated zoom, and comparable curves

Displays are zoomable with animation, facilitating fine inspection of critical areas. You have instantaneous, peak, and average curves to understand both transient behavior and overall trends. The 4 memory slots allow saving curves for quick A/B comparisons between multiple tracks, settings, or even between your mix and a reference track.

Mono compatibility, correlation, and phase diagnostics

StereoScope Pro includes a correlation meter and reading tools designed to easily detect phase cancellations. You identify risky sources faster (wideners, doubles, spaced mics, chorus), and validate your mix's robustness when played in mono (smartphones, clubs, connected speakers, broadcast).

Automation and MIDI output: an analyzer that becomes a controller

Beyond display, the plug-in can generate automation curves or send MIDI CC messages from its output parameters: minimum/maximum position in the stereo field and perceived position based on energy distribution. A powerful solution to create dynamic interactions (e.g., adjusting processing based on the actual signal width), while maintaining a clean workflow via your DAW's automation.

Pro workflow: customizable interface, optimized CPU, host integration

Thanks to interface customization (transparency and zoom) and opacity management, you adapt StereoScope Pro to your working environment. The plug-in also offers a set of production-oriented standards: MIDI Learn, full automation support, Smooth Bypass (noise-free activation/deactivation), Undo/Redo, preset manager, and copy/paste state between instances. Finally, CPU load is optimized: no processing when the signal is silent.
