METHOD AND DEVICE FOR ACOUSTIC SIGNAL RENDERING AND MACHINE-READABLE RECORDING MEDIA Russian patent published in 2018 - IPC H04S5/00 G10L19/08 

FIELD: communication equipment.

SUBSTANCE: invention refers to communication engineering. This method receives the multi-channel signal, which includes the plurality of input channels that are to be converted to the plurality of output channels; adding the preset delay to the front input high-altitude channel, so as to enable each of the plurality of the output channels to provide the audio image that has the ascending with the reference ascending angle; the change, based on the added delay, the ascending rendering parameter relative to the front input high-altitude channel and preventing the confusion of the front/rear channels by means of forming, based on the modified ascending rendering parameter, the spatial sound output channel after the ascending rendering, which is delayed with respect to the front input high-altitude channel.

EFFECT: reduced distortion of the audio image, when the input channel is raised above or below the standard ascending, by means of converting the channel audio signal using rendering.
