How to use Extract local audio

Save WAV or supported Ogg Opus from a local media track. MP3 output copies an already-MP3 track only.

  1. Choose one local file or use the synthetic sample, then set the options. No reading or encoding starts until the action is chosen.
  2. One file ≤30 MiB / 60 seconds; one audio + one video track; mono/stereo 8–48 kHz; SDR video ≤1080p / 30 fps / 1,800 frames. Output ≤32 MiB. Native codecs vary.
  3. Video is intentionally discarded. MP3 does not convert AAC/Opus to MP3; it only copies an existing MP3 track. No MP3 encoder is shipped. Source metadata, chapters and original compression are discarded. Codecs must be available locally; no upload or server fallback. Re-encoding changes quality.
  4. Run locally and review the result. Downloaded files remain on your device. Edit, Clear or leaving discards the old result; Cancel terminates its worker. No file or result is uploaded or stored in your account.
