Abstract (en)
[origin: WO2007027055A1] The invention relates to a method for decoding an audio signal, to allow an audio signal to be compressed and transfered more efficiently. The inventive method comprises steps of receiving an audio signal with spatial information signal, obtainning location information using the number of time slot and parameter of audio signal, establishing a multi-channel audio signal by applying spatial information signal to down-mix signal, and performing a multi-channel array for a multi-channel audio signal in response to the output channel.
