A portable audio system includes a compact disc drive (12) and a control unit (14) communicable through a communication interface (18). The control unit (14) includes a user interface (20), a processing means (22), memory (24), and an audio output (26). The control unit (14) is detachable from the compact disc drive (12), and is operable while disconnected from the compact disc drive (12). The processing means (22) of the control unit is configured to read data from a compact disc within the compact disc drive (12). The processing means can encode the data into digitally formatted files, and store the files within the memory (24) of the control unit (14) while the control unit (14) is connected to the compact disc drive (12). The processing means (22) can read, encode, and store the data at a rate equal. to or faster than the normal rate of play of the data. The processing means (22) of the control unit can produce an audio signal representative of the data in one of the files stored within the memory regardless of whether the control unit (14) is connected to the compact disc drive (12). |
