Method and system for storing digital audio data and emulating multiple CD-changer units |
摘要 |
A method for processing digital audio data is presented. A control signal for a CD-changer unit is received and interpreted by a digital audio unit that stores digital audio data/files and that determines a CD-changer unit operation that would be performed by the CD-changer unit in response to the CD-changer unit receiving the control signal. The digital audio unit then emulates the CD-changer unit operation. The CD-changer unit to be emulated by the digital audio unit can be selected. The digital audio data stored by the digital audio unit can be organized as virtual CD-ROMs. By emulating the operations of multiple types of CD-changer units, a single digital audio unit can be inserted in many different digital audio systems, thereby extending the functionality of a digital audio system to include storage of softcopy digital audio files that may be accessed through controls and commands for a CD-changer unit.
