DDMF has released Chorddetector, an mp3/wav-player with an integrated chord detection algorithm.
It’s extremely simple to use: just load the song whose chords you’re interested in, press play and see the displayed chords in realtime, so that you can play along with your instrument.
Very useful for covering songs, which, as we all know, is the basis of virtually all successful band careers!
Chorddetector for Windows and Mac is available to purchase for $15 USD. A demo version is ready for download as well.
