ABSTRACT:
A circular buffer in a system for processing audio samples wherein the buffer includes a sample window, the length of which is the length of a plurality of samples, the length of the circular buffer is a multiple of the length of the sample window, and the entire sample window is treated as a contiguous linear address space on each iteration of the processing system, that is moved through the physical multiple sample length buffer between iterations of the processing system, and is reset to the beginning every sample window number of iterations of the processing system. The circular buffer substantially reduces the number of address calculations in processing systems where every buffer position is addressed on every iteration and where circular addressing is not provided in hardware.
