Abstract: A CD-based application program must often be run in conjunction with its associated CD. Described herein, however, is a method that allows such an application program, without any modifications, to render its CD "Redbook" audio content from a storage device other than the associated CD. The method includes converting the Redbook audio content of the CD to an alternative single-file format such as a "WAVE" file format that is suitable for rendering on a local sound board. The file is stored on a local or network logical drive. In place of the simple device driver that is normally used by the application program to render CD audio from a local CD drive, a proxy device driver is installed. In response to instructions from the application program to render audio using the local CD drive, the proxy device driver instead reads the file from the local or network drive, and renders the file on a local sound card.
