METHOD AND APPARATUS FOR PROCESSING AN AUDIO SIGNAL |
摘要 |
A method and an apparatus for processing audio signals are provided to enhance the quality of the audio signals by executing selectively decoding on extension signals. An ancillary signal for generating audio signals and an extension signal included in the ancillary signal are extracted from bitstreams, which are received(1410). Length information of the extension signal is read out(1420). Decoding of the extension signal is omitted by the length information or a decoded result is not utilized(1440). The audio signals are generated using the ancillary signal(1470). The extension signal is a residual signal. The length information of the extension signal is allocated based on a fixed bit.
