1. Who We Are

AudioLab is a free, browser-based audio analysis tool available at audio.rswaver.com. It is operated as an independent service.

2. Audio Data

All audio processing — including BPM detection, LUFS measurement, key detection, spectrum analysis, and microphone testing — is performed entirely within your browser using the Web Audio API. Audio files you drop onto the page, or microphone input, never leave your device. We have no access to your audio content.
