Normalize audio to target LUFS

Upload an audio file and create a normalized copy with target integrated LUFS, true peak ceiling and loudness range settings.

The server uses ffmpeg loudnorm in two passes and returns a before/after loudness report for podcasts, online video, broadcast, music and voice recordings.

Browser-side media tools are useful for quick analysis, previews and lightweight exports.
Large video and audio files may need time to decode; smaller samples work faster in the browser.
When the result is a command, run it on a machine with ffmpeg or the required model installed.
Review generated WAV, PNG, CSV and command outputs before using them in production workflows.
Fullscreen mode on tablets and desktops gives more room for waveforms, tables and video previews.
For final broadcast, podcast or advertising delivery, verify results with professional media tools too.
