What this version supports
This is basic browser-side processing rather than a full mastering suite. Peak and RMS figures are not integrated LUFS measurements.
Private audio processing
Audio is decoded and processed in your browser; WAV export stays local. If you choose MP3 export, the processed selection is sent to this server for FFmpeg encoding only after you opt in. Large files require memory and browser codec support can vary.
