FIELD: audio coding. ^ SUBSTANCE: with the binaural coding, only one monophonic channel is coded. An additional layer contains parameters for the LH and RH signals. A coder is described, which associates transient process information extracted from the monophonic coded signal with parametric multichannel layers. Transient process locations may also be determined directly from the bit flow or calculated using other coded parameters (e.g., the window switch flag if specified in customer's requirements). ^ EFFECT: increase in efficiency due to use of transient process information in parametric multichannel layer. ^ 13 cl, 4 dwg
