What Blue Cat’s StereoScope Pro does
The plugin is built around a real-time stereo image analyzer. Three detailed views are offered: the stereo image, a stereogram showing how the image evolves over time, and output parameters. All views are zoomable and animated, and a 3D waterfall view can be rotated to any viewpoint, with a solid wireframe 3D surface display as an alternative. An integrated correlation meter and instant peak and average stereo image curves complete the measurement set, and phase cancellation problems that affect mono compatibility are easier to spot in the displays.
Analysis data can be saved as curves, with four memory slots for storing any curve, which makes A/B comparison between tracks, effects setups and commercial reference mixes straightforward. The user interface has an opacity control and a customizable skin with transparency management. The plugin is available as VST3, VST2, AU and AAX for Windows and macOS, with the macOS build listed as 32-bit only, native support for Apple Silicon, and a trial version. Activation is not described in the developer notes provided here.
Analysis output parameters can be recorded as automation curves or sent as MIDI CC messages, including generated automation envelopes that carry minimum and maximum positions of the stereo field. A smooth bypass switches processing without noise, and parameter updates are zipper-free with full MIDI control and automation support.
Key features
- Three analysis views. The stereo image, the stereogram evolution over time and the output parameters can each be shown in its own view, and the preferred view can be chosen to match the monitoring need.
- 3D waterfall and surface displays. The waterfall view offers full 3D control to see detail from a preferred viewpoint, and a solid wireframe 3D surface display is available as a second 3D representation.
- Correlation meter and curves. An integrated correlation meter sits alongside instant peak and average stereo image curves, which can be saved for later comparison.
- Memory slots and comparison. Four memory slots store any curve, so comparisons between several tracks, effects setups or other commercial hits can be made without re-running the analysis.
- Automation and MIDI output. Output parameters can be recorded as automation curves or sent as MIDI CC messages, and smooth bypass with zipper-free updates avoids noise when parameters change.
- Skinnable interface. The interface can be skinned and customized, with an opacity control and transparency management for the displays.
Compatibility
The plugin comes as VST3, VST2, AU and AAX for Windows and macOS, with the macOS build listed as 32-bit only. Minimum OS is macOS 10.9 and Windows 7, and native support for Apple Silicon is listed.
