What this version supports
Batch outputs are WAV files inside an uncompressed ZIP. Browser memory limits apply; total source files and estimated output are limited to about 100 MB. MP3 batch encoding is not included.
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.
