0 bytes uploaded. Peak Volume Normalizer runs entirely in your browser using FFmpeg.wasm 8.1, RNNoise, and the Web Audio API. Your audio stays on your device at all times. No data is sent to any server — critical for sensitive interviews and confidential calls.

Two-pass EBU R128 loudness normalisation in your browser. Hit -16 LUFS for podcasts, -14 for Spotify/YouTube — true-peak limited, FFmpeg 8.1 engine, no upload.
