AUDIO PROCESSING

摘要

Audio processing apparatus in which two audio signals are compared to establish differences between the two audio signals comprises means for deriving, from the two audio signals, a transform response representing a relationship between the two audio signals; means for applying the transform response to one of the audio signals so as to generate a transformed signal which is more like the other audio signal; and means for detecting a difference signal representing differences between the transformed audio signal and the other audio signal.
