摘要 |
PCT No. PCT/EP93/00629 Sec. 371 Date Nov. 21, 1994 Sec. 102(e) Date Nov. 21, 1994 PCT Filed Mar. 17, 1993 PCT Pub. No. WO93/19542 PCT Pub. Date Sep. 30, 1992In order to transmit or to store digitalized, multi-channel audio signals which are digitally represented by a plurality of spectral subband signals, at an encoder, subband signals of different audio channels but having the same frequency position are combined across channels according to a dynamic control signal. This control signal is derived from several audio channels by an audio signal analysis based on a psycho-acoustic binaural model. At a decoder, the subband signals of several audio channels but having the same frequency position are dissociated across channels according to a control value derived from the dynamic control signal, transmitted or stored therewith. |
