0 bytes uploaded. True-Peak Limiter 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.
Lossy codecs (MP3, AAC, Opus) can introduce inter-sample peaks above 0 dBFS during decode. Limiting to -1 dBTP gives a safety margin that survives encoding without distortion.
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.
Open toolSmooth out loud and quiet passages so voices sit consistently in the mix. Broadcast-style compression with adjustable threshold, ratio, attack, and release.
Open toolBoost (or attenuate) audio so its loudest sample sits at a chosen ceiling. Faster than EBU R128 — for quick consumer-grade leveling.
