About Blue Cat Audio

Blue Cat Audio is a Paris-based developer founded by Guillaume Jeulin, who remains CEO and principal developer. The company builds audio and MIDI plug-ins in VST, VST3, AU, and AAX formats, plus standalone applications. Blue Cat is known for deep visual analysis tools like FreqAnalyst, StereoScope, and DP Meter Pro, and for plug-in hosting environments like PatchWork and MB-7 Mixer that let you route other plug-ins inside a single instance. The company also offers Plug'n Script, a scripting environment where you can write your own DSP. Blue Cat licenses its plug-in SDK to other developers and has exhibited at NAMM for roughly a decade. All interfaces are fully skinnable using Blue Cat's own skinning language.

Analysis and Metering Tools

Blue Cat's analysis plug-ins give you precise visual feedback on frequency content, stereo imaging, and waveform behavior. FreqAnalyst Pro delivers real-time spectrum analysis with multiple display modes and overlays. StereoScope Pro maps stereo width and phase correlation in a single view. Oscilloscope Multi shows waveforms across multiple tracks simultaneously. DP Meter Pro tracks peak and RMS levels with detailed metering standards. These tools are built for mastering engineers, mix engineers, and anyone who needs to see what's happening in the signal path, not just hear it.

Plug-in Hosting and Routing

PatchWork is a modular plug-in host that loads other plug-ins inside it, letting you build custom chains, split signals, and route audio in ways your DAW doesn't natively support. MB-7 Mixer is a multiband processor that hosts up to seven plug-ins across different frequency ranges, so you can compress lows separately from highs or apply different saturation to each band. Late Replies is a creative delay host that runs other plug-ins in its feedback loop. These tools turn your existing plug-in library into a more flexible system without adding new processors.

Guitar and Amp Modeling

Re-Guitar is an amp and cab simulator with a straightforward signal chain: preamp, tone stack, power amp, and cabinet. AcouFiend models acoustic guitar body resonance and pickup response. Hot Tuna is a bass amp simulator. Destructor is a distortion and amp modeling plug-in with waveshaping and filtering. These tools are aimed at guitarists and bassists recording direct, offering tone shaping without needing to mic an amp. Re-Head is a guitar reamping tool that lets you send a dry signal back out to hardware and re-record it.
