About Audio Analyzer

Audio Analyzer

A measurement bench for any recording you drop in or capture. It reports peak and RMS levels, DC offset, noise floor and signal-to-noise, clipping runs, stereo correlation, spectral centroid and rolloff, the upper band edge that reveals lossy encoding, and mains hum resolved to 50 or 60 Hz.

Analysis runs in a worker over the decoded buffer, so the same file measured twice gives identical numbers. Every finding is shown with the measurement it rests on, and a selection can be re-measured on its own. It describes recordings; it does not identify their causes.

This is an instrument and a sound tool, provided for entertainment and experiment. It describes what it measures and does not identify the cause of anything it shows.
