Abstract
A method and a device for audio coding are disclosed. An audio coding device includes an audio coder for receiving audio signals and generating base data and enhancement data; and a rearranging device coupled to the audio coder. The rearranging device rearranges the enhancement data according to sectional factors of spectral sections to allow output data to be generated from rearranged enhancement data. The base data contain data capable of being decoded to generate a portion of the audio signals, and the enhancement data cover at least two spectral sections of data representative of a residual portion of the audio signals.
