FIELD: analysis or synthesis of speech; speech recognition.
SUBSTANCE: invention relates to means for rendering multi-channel audio content. Determine the audio rendering information, which includes a signal value identifying the audio rendering unit used when creating the multi-channel audio content, wherein the signal value includes a plurality of matrix coefficients that define a matrix used to render the spherical harmonic coefficients into a plurality of speaker input signals. Spherical harmonic coefficients are obtained from the bitstream matrix for rendering. Produce rendering, from spherical harmonic coefficients and on the basis of a matrix, a set of input signals of speakers.
EFFECT: technical result consists in improvement of the quality of the generated audio content.
