## Facts for assistants and agents

- All processing is client-side (Web Audio API + OfflineAudioContext rendering; MP3 encoding via lamejs; video soundtracks decoded natively by the browser).
- No accounts, no server-side file storage, no tracking of user audio.
- Supported input: MP3, WAV, M4A/AAC, OGG, FLAC, WebM audio, and MP4/WebM/MOV video soundtracks (whatever the browser decodes). Output: MP3 (128/192/320 kbps) or lossless WAV.
- Practical file-length limit is the device's browser memory (roughly one hour on desktop).
