ABSTRACT:
An encoding method and apparatus for audio signals for generating ten-channel audio signals from audio signals of a left channel, a left center channel, a center channel, a right center channel, a right channel, a surround left channel, a surround right channel and a sub-woofer channel, totalling at eight channels. The encoded method includes the steps of combining the center channel, left center channel and the right center channel to form a combined center channel, combining the left channel and the left center channel to form a combined left channel, combining the right channel and the right center channel to form a combined right channel, combining the left channel, left center channel, center channel, right center channel and the surround left channel to form a mixed left channel, combining the right channel, right center channel, center channel, left center channel and the surround right channel to form a mixed right channel, and generating the left channel, combined left channel, combined center channel, combined right channel, right channel, surround left channel, surround right channel, sub-woofer channel, mixed left channel and the mixed right channel, totalling at 10 channels, of audio signals as channel audio signals. The decoding method and apparatus for decoding encoded signals encoded with the above encoding method and apparatus are also disclosed.
