Abstract
An audio processing apparatus for processing two sampled audio signals to detect a temporal position of one of the audio signals with respect to the other. The apparatus detects audio power characteristics of each signal in respect of successive continuous temporal portions of each of the two signals, the portions having identical lengths and each portion including at least two audio samples, and correlates the detected audio power characteristics in respect of the two audio signals to establish a most likely temporal offset between the two audio signals.
