Abstract
An audio comparison method and apparatus compares audio streams by measuring the times of volume peaks in the audio streams and identifying correlations between the peaks in the audio streams, subject to possible delay between the streams. The audio comparison allows the identification of audio streams including the same audio content even in the presence of delay and distortion and using low processing power. The audio comparison has particular application in car radios to allow automatic retuning.
