ABSTRACT:
A programmable multi-channel audio playback system includes a tape having recorded thereon a plurality of segments of information on multiple channels, with the segments being separated by gaps containing no information, control apparatus for causing the tapes to move and for controlling such movement, reading apparatus for reading the information segments from the tape as the tape is moved, speaker apparatus for producing audio sounds from the information segments read by the reading apparatus, a microprocessor responsive to input signals for signalling the control apparatus to control movement of the tape and for signalling the speaker apparatus to control production of the audio sounds, and a manually operable keyboard for generating input signals which are supplied to the microprocessor. By keying certain information on the keyboard, the microprocessor is programmed to cause the reading from the tape of selected information segments and the production of audio sounds therefrom. The information segments may be read from the tape in any order desired and only selected information segments need be read.
