ABSTRACT:
In one embodiment, the method includes receiving the audio signal including a block of audio data partitioned into N sub-blocks, and restoring a plurality of code parameters s(0), s(1), . . . , s(N−1), respectively. The restoring step includes detecting s(0) from the audio signal, where s(0) represents the code parameter of the first sub-block; detecting a difference s(i)−s(i−1) from the audio signal for i=1, . . . N−1, where s(i) representing the code parameter of each sub-block following the first sub-block. The difference s(i)−s(i−1) is encoded by using first entropy code. The restoring step further includes calculating s(i) for i=1, . . . , N−1 using s(0) and the detected differences, and the method further includes decoding the N sub-blocks using the restored code parameters.
