ABSTRACT:
An audio player permits compressed or uncompressed audio CDs to be played. The preferred player includes a spindle motor control that causes the CD to be spun at a constant linear velocity that is commensurate with the encoding rate of the file being played. In this manner, the data can be continuously pulled of the CD at just the right rate so that, after being decoded and decompressed, the data can be played. The player also dynamically adjusts its constant linear velocity to the encoding rate of the file being played to permit files on the same disc having different encoding rates to be played.
