Waveform
Downsampled peaks and RMS envelope across the track.
Four steps from sound to signature.
Pick any audio file from your music folder.
We decode the file with the Web Audio API in your browser.
Rhythm, energy, spectrum, harmony, and structure are extracted from the signal.
Deterministic visualizations are rendered from the real analysis.
Every visual is rooted in measured signal features.
Downsampled peaks and RMS envelope across the track.
Onset strength, beat times, and BPM estimate via autocorrelation.
FFT frames, spectral centroid, flux, and low/mid/high balance.
Chroma vector and key estimate via Krumhansl-Schmuckler profiles.
Section boundaries from spectral and energy novelty.
Loudness curve, dynamic range, loudest and quietest moments.
Not every feature is available for every track. Uncertain values are clearly labelled as estimates.
