APPARATUS AND METHOD FOR GENERATING PLURALITY OF AUDIO CHANNELS Russian patent published in 2019 - IPC H04S3/02 G10L19/08 

FIELD: acoustics.

SUBSTANCE: invention relates to means for generating a plurality of audio channels. Position of an imaginary speaker not contained in the first speaker setup is determined. Second speaker setup is obtained, comprising an imaginary speaker and, at least partially, speakers of the first speaker setup. Energy distribution from the imaginary speaker to other speakers in a second speaker setup is calculated, wherein the energy distribution is the amount or fraction of the energy of the imaginary speaker distributed to other speakers in the second speaker setup. Degree (Dⁿ) of the energy distribution matrix is calculated to obtain downmix information, for downmixing from the second speaker setup to the first speaker setup.

EFFECT: technical result high flexibility of speaker setup.
