As I try to play along with songs that I have on CD's or have in MP3 format I find that once I know the key, I can usually work out a lot of the song. However, I often have real difficulty in figuring out the key and some of the chord changes. As my ear improves it gets easier, but I still want to be able to check to see if I have heard it right.

I'm looking for software that can tell the key and/or chords of a song that is playing from a CD or MP3. Does anyone know of a Winamp or other plugin that can do this? Hey can anyone help?

I have read the past threads and it seems that there a lot of programs that read and analyze midi files, but none for native audio files.

I did find one Shareware program called Note Chaser out of England that will help transcribe every not played, but you first have to convert each song that you want to examine into a WAV file and save it to your hard disk. It does more than I need but it is really really cool.

Does anyone know of any other options?
