AuraOrigin — Digital vs. Natural Sound Estimator

--%

Natural / Analogue

Digital Origin

Capture chain contamination: The microphone ADC introduces its own digital artifacts. The engine attempts to look past this, but the signal is inherently coloured.
Browser DSP: Browsers may apply echo cancellation, noise suppression, or AGC before the Web Audio API receives data. Disable system-level audio enhancements for best results.
Heuristic, not ground-truth: This is a probabilistic estimator. High-fidelity digital playback through quality monitors may score "Natural."
Room acoustics: Reverberation and standing waves affect spectral flatness and coloration metrics.
