ABSTRACT:
Scalable stereo audio coding and decoding method and apparatus are provided. The scalable stereo audio coding method includes transforming a first channel and a second channel audio samples; quantizing the transformed first channel and a second channel audio samples; and coding the quantized first channel audio samples up to a predetermined transition layer and then interleavingly coding the quantized first and second channel audio samples with increasing a layer index from a layer succeeding the transition layer, until coding for a predetermined plurality of layers is finished.
