Abstract
A solid state audio system provides audio signals when played in an audio cassette player. The audio system is provided in a casing having the same size as a standard audio cassette tape and includes an audio tape, a sensing mechanism providing signals indicating a speed and a direction of travel of the audio tape, a processor coupled to the sensing mechanism and a memory card coupled to the processor and storing digitized audio information. The audio system also includes an audio transfer system coupled to the processor and magnetically coupled to the audio tape for transferring audio signals onto the tape corresponding to the digitized audio information. A solid state audio player is also provided that includes a memory card having digitized audio information stored thereon, a processor coupled to the memory card, a D/A converter coupled to the memory card and the processor. The D/A converter outputs an analog audio signal. The player also includes a plurality of control inputs, the control inputs are selectable for placing the audio player in one of several states. A selected portion of the digitized audio information is output to the D/A converter in response to the state of th…
