Extract high quality audio now →Supported input formats
- MP4 — Most common format. Usually contains AAC or MP3 audio.
- MOV — Apple's QuickTime format. Often contains high-bitrate PCM or AAC audio.
- WebM — Open format. Typically uses Vorbis or Opus audio codec.
- AVI — Legacy format. May contain uncompressed PCM audio — excellent quality, large file.
Output format quality comparison
- WAV — Uncompressed, perfect quality. Good for editing but file sizes are huge (about 10MB per minute for stereo 16-bit).
- FLAC — Compressed but lossless. Same quality as WAV, about half the size. Good for archiving.
- AAC / M4A — Excellent quality at moderate bitrates. 256-320 kbps is indistinguishable from original for most people.
- MP3 — Universal compatibility. 320 kbps is nearly transparent; 192 kbps is good for mixed use.

When quality matters most
- Music production — Use WAV or FLAC to preserve every detail for sampling or remixing.
- Podcast editing — 192 kbps AAC is more than enough and keeps file sizes manageable.
- Personal archive — 256 kbps AAC strikes the perfect balance of quality and storage.

Does extraction reduce quality?
If the audio codec matches the output format, MEDIA FLOW uses stream copy (remux) — zero quality loss. When re-encoding is needed, you control the bitrate, so quality is always your choice.
