FIELD: information technologies. ^ SUBSTANCE: invention relates to method and/or device for coding and/or decoding of sound signal, in which in coding device amplification of mixing with reduction of channels number is applied to signal mixed by reduction of channels number. At the same time device of coding transmits a flow of bits that contains information on applied amplification for mixing with reduction of channels number into decoding device. Decoding device restores the signal mixed by reduction of channels number with application of information on amplification for mixing with reduction of channels number. Also method and/or device for coding and/or decoding of sound signal are disclosed, in which coding device applies arbitrary amplification for mixing with reduction of channels number (AAM) to signal mixed by reduction of channels number, performs transmission of flow of bits that contains information on AAM applied into decoding device. Decoding device restores the signal mixed by reduction of channels number with application of information on AAM. Also method and/or device for coding and/or decoding of sound signal are disclosed, in which level of separate channel energy is changed, and changed level of energy is restored. ^ EFFECT: restoration of loudness level and improved quality of sound. ^ 10 cl, 24 dwg |
