DEVICE AND METHOD OF TRANSFORMING FIRST AND SECOND INPUT CHANNELS, AT LEAST, IN ONE OUTPUT CHANNEL Russian patent published in 2018 - IPC H04S7/00 G10L19/00 

FIELD: physics.

SUBSTANCE: spatial encoding of audio begins with a number of source inputs, such as five or seven input channels, which are identified by placing them in the layout for playback as a left channel, a central channel, a right channel, a left surround channel, a right surround channel, and a low frequency enhancing channel (LFE). In the device, each input channel and each output channel has a direction, in which the associated loudspeaker is located relative to the center position of the listener, wherein the device is configured to convert the first input channel to the first output channel from the configuration of the output channels.

EFFECT: improved audio reproduction in case of format conversion between different speaker channel configurations.
