about: カラオケ (ka-ra-o-ke) means 'empty orchestra' in Japanese. It refers to the instrumental, or off-vocal, versions of songs so people can sing over them. This application can try to help you remove the main vocals from an audio file and make it downloadable as a .wav file.

note: it is most probable that the file returned will not be in the same quality it came in as. if you only want instrumentals for understanding how a song/piece works (for transcribing/arrangement purposes), then I think this tool would serve well.

I also highly recommend trying this application out on game music or orchestral pieces that have no vocals. Many times interesting harmonies and instrument parts that aren't obvious become illuminated!
