Abstract
The present invention relates to an audio signal processing method, comprising the steps of: receiving a bit-stream containing a normal channel signal and an exceptional channel signal; decoding the normal channel signal and the exceptional channel signal from the received bit-stream; generating correlation information using the decoded normal channel signal and the decoded exceptional channel signal; generating a gain value by at least one of a first downmix method applying the same downmix gain value using the correlation information and a second downmix method applying variable gain values over time; and outputting the exceptional channel signal as a plurality of channel signals using the gain value.
