Peggo is a Digital Video Recorder (DVR) that records MP3s of your favorite online videos.
Peggo’s packed with great features like integrated search, automatic silence removal, audio normalization, subtrack offsets, and artist and title tags.
Peggo automatically removes unwanted silence from the beginning and end of videos so you get a beautiful MP3 with just the good stuff. In addition, Peggo also normalizes the volume of every recording to the same, comfortable level so you never have to reach for the volume dial between MP3s again.
Many times the audio from a YouTube video is all you need to have an impact in the classroom. This looks like a useful, and apparently legal tool that extracts the audio and creates an mp3 file for you. I will play around with it to see what the limitations are, but I can see the music industry having some issues.
