“listen to your material (e.g. recorded radio shows, live performances, dj sets) through winamp and with the help of mp3extractor, find the portions, parts or tracks of interest, drop markers at the desired start and stop times of these takes and optionally add track information. mp3extractor includes many features for navigating swiftly through even lengthy input files, checking and fine tuning marker positions. when you’re done, mp3extractor will copy the corresponding mp3 frames to new mp3 files properly name and tag these output files and optionally write track information to a database list.”
