FIELD: communication.
SUBSTANCE: invention relates to simultaneous rendering of multi-channel signals. An audio signal processor receives a plurality of encoded multi-channel audio signals. A multi-channel decoder decodes a first encoded multichannel signal, to generate the first decoded multi-channel signal. A generator generates an encoded further audio signal selecting audio encoding data. A further decoder generates a further decoded signal by decoding the further encoded audio signal. A combiner combines the first decoded multi-channel signal and the further decoded signal to generate a multi-channel output signal.
EFFECT: technical result is improved processing, maintaining low complexity and and/or reduced computational load, improved audio quality and facilitated operation.
