Converting FLV to MP3: what to know

FLV is the Flash video format that websites once used to stream videos; old downloads and archives are full of such files. Converting FLV to MP3 keeps the music, a talk or an interview so it plays on any device.

Only the audio track is kept and the video is dropped, so the file becomes many times smaller. You can save just a fragment by setting the start and end on the timeline. For music choose 192–320 kbps; for speech 96–128 kbps is enough.
