When to Convert
Common scenarios where this conversion is useful
Extract audio from legacy AVI video files
AVI was the dominant Windows video format for decades. Extract audio from old home movies, camcorder recordings, or archival AVI files as WAV for lossless preservation.
Pull dialogue or music from an AVI movie
Have an old movie or TV episode in AVI format? Extract the audio track as WAV to create audio clips, study audio quality, or use the soundtrack in other projects.
Get audio from a DivX or Xvid AVI for editing
Many compressed DivX and Xvid videos use AVI containers. Extract the audio as WAV for importing into audio editors or video production tools that need an uncompressed audio source.
Archive camcorder footage audio
Old camcorder recordings often use AVI format. Extract the audio as WAV to preserve it separately in lossless format, even as the video file is converted or compressed further.
