Convert to mp3 files.

Um, WMA and FLV are both video files, you should know. But they can still be converted. -http://media-convert.com/ - Online, if you want to just quickly convert a file without installing software. -www.aoamedia.com/audioextractor.htm - AoA Audio Extractor will extract the audio from a video file, and should work on both WMA and FLV (as long as the WMA isn't protected.) Hope those work for you!
