About FLV to MP3 conversion

FLV files are video files, but sometimes the picture is not the useful part. For Flash-era videos, old site clips and archived web recordings, the audio may be what you actually need.

Converting to MP3 separates the sound from the video and creates a smaller file for listening, editing, transcription or sharing.

The conversion does not restore detail missing from the original recording. It simply gives you the audio in a format that is easier to use.
