Interactive psychoacoustic tools and audio analysis, running directly in the browser
No install, no plugin host, nothing leaves the device. These are built with the Web Audio API, canvas rendering, and in one case a C++ DSP core compiled to WebAssembly — the same real-time signal processing used in the native plugins, running client-side instead.
Drop an audio file and get its psychoacoustic fingerprint: dominant perceptual zone, spectral centroid, and masking risk, calculated from real FFT data rather than a fake spectrum display. Exports as structured JSON metadata for stems or sample packs.
Real-time microphone analysis directly in the browser — frequency spectrum, waveform, and perceptual activation metrics. Runs over HTTPS with no install required.
Drop or load audio files for waveform view, FFT frequency histogram, Wwise-relevant properties (trim points, peak/RMS dBFS, dynamic range, DC offset, zero crossings, loop suitability), and cross-file compatibility scoring for spectral conflicts.
Six real-time auditory illusions powered by the Web Audio API — from phantom imaging to infinite tones — as a hands-on way to hear how perception diverges from the raw signal.
These aren't just visualisations of pre-baked data. Spectra Stamp and the Acoustic Analyzer run genuine FFT analysis client-side; Echo Chamber (linked from the DSP Plugin work) runs an actual C++ reverb and delay engine compiled to WebAssembly via Emscripten, with the JavaScript layer doing nothing but audio I/O.
A browser demo removes every barrier between "here's a description of what it does" and "try it right now." For psychoacoustic work specifically, that matters: masking, spatial illusions, and perceptual metrics are much easier to trust once you can hear or test them yourself, rather than take a claim on faith.
