Blue Cat's FreqAnalyst is a free audio-analysis plugin for Windows and macOS. It analyzes audio in real time and presents results as a spectrum, instant curve, or peak curve, with a maximum of two channels. Listed formats are VST, VST3, AAX, and Audio Unit; VST support is also specified separately. The product is described as a bundle, and its listed effect types span analysis, EQ, filters, dynamics, distortion, delay, reverb, modulation, guitar, multi-effects, routing, and mixing. An IR loader is included. FreqAnalyst is not a standalone app, so it must be used as a plugin in an audio setup that supports a listed format. Its free plan has no listed paid tier. Blue Cat Audio is headquartered in Paris, France. The key fit considerations are whether the available analysis views and two-channel ceiling meet the task, and whether the plugin formats match the intended setup.
Who it is for
It suits audio users who want real-time spectrum and curve analysis in a plugin, rather than a standalone app. The two-channel maximum and supported plugin formats are important fit considerations.
