Getting the sound out of AVI
AVI is a Microsoft container from 1992. It still turns up in old archives, camcorder dumps and downloaded footage, but it predates modern compression and has no idea what a phone is.
The picture is dropped and the audio is written as MP3 (MP3 (lossy)), which every phone, car stereo and podcast host plays. If the AVI carries several audio tracks, the MP3 carries one of them. Your AVI itself is not changed.

| File size | Very large for the quality | Roughly a tenth of uncompressed audio |
Before you extract audio from an AVI
No browser plays AVI, so an AVI cannot be previewed or embedded on a web page without converting it first.
AVI files from older cameras and downloads often hold DivX, Xvid or MJPEG video, which modern phones and TVs frequently refuse even when the extension looks familiar.
extract audio from avi: questions
Can I get WAV instead of MP3?
Yes. Switch the output to WAV in the panel before exporting. WAV is uncompressed, so it is several times larger, and it is what an audio editor would rather have.
Does my AVI lose anything?
No. REQO reads the audio out of your AVI and writes a new file; the AVI you uploaded stays exactly as it was.
Is extracting audio from AVI free?
Yes. Extract and preview free, and a free account downloads the result. Free exports and share pages include a small REQO badge. Go Pro to remove it.
