Abstract
An efficient low latency buffer, and method of operation, is described. The efficient low latency buffer may be used as a bi-directional buffer in an audio playback device to buffer both output and input data. The audio buffer includes two modes of operation. The first mode replaces large segments of data at a first rate, and the second mode replaces smaller segments of data at a second rate, higher than the first rate. The first mode may make efficient use of the buffer for the output, data while the second mode may provide low latency for the buffering of the input data.
