What this version supports
This is a lightweight multitrack mixer rather than a full DAW. Project length is limited to five minutes and browser memory availability affects how many tracks can be loaded.
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.
