ABSTRACT:
Variably delaying an audio signal by storing digital representions of the audio signal at sequential memory locations prescribed by an encoding pointer operating at one clock rate, and reading from the memory at sequential locations prescribed by a decoding pointer operating at the same or a different clock rate, with the difference in clock rates between the pointers prescribing the rate of change of delay. A memory addressing system in which a processor specifies the high-order portion of a memory address and a separate counter, clocked at a much higher rate than the processor, provides the low-order portion of the address.
