HARP can acquire and play audio from both traditional and Internet-based sources. The device uses standard audio connectors to connect to other stereo equipment. Audio sources can include CDs, LPs, tapes, and numerous Internet streaming audio formats. Users can then direct this output to multiple end-points simultaneously, including CD burners, MP3 players, or simple playback on any networked device in the home. As an audio hub, HARP can access, store, and organize both Internet-source music and traditional media for an entire household.
Users can customize playback, adding audio and even video output effects.
HARP is designed to be integrated into components produced by consumer electronics companies and home stereo component manufacturers. Device providers can use HARP's modular design to incorporate a range of capabilities into a branded consumer device. Remote maintenance of the device is possible because of HARP's MAP functionality. Providers can update and change the device without end-user intervention. This allows vendors to accomodate new file formats.
