FIELD: physics; acoustics. ^ SUBSTANCE: invention relates to processing audio signals and more specifically to a device and a method of decoding an audio signal. The decoding method comprises steps for receiving an audio signal using a spatial information signal, obtaining position information using a number of time intervals and audio signal parametres, establishing a multichannel audio signal by applying the spatial information signal to a reduction mixing signal and creating a multichannel matrix for the multichannel audio signal in response to the output signal. ^ EFFECT: more efficient compression and transmission of audio signals. ^ 16 cl, 8 dwg |
