Abstract
A storage device for use with a synthesizer of original information bearing time domain signals from compressed information time domain signals produced by predetermined different signal compression techniques. The storage device contains compressed information time domain signals and instruction signals specifying the particular compression technique applied to the original information bearing time domain signals to produce corresponding portions of the compressed information time domain signals. The compressed information time domain signals comprise a plurality of samples resulting from the predetermined signal compression techniques, the number of the different signal compression techniques applied to the original signals being greater than two and the ratio of the plurality of the samples to the minimum number of samples required to uniquely and intelligibly identify the original information bearing signals being no greater than about 0.2.
