METHOD AND DEVICE FOR RENDERING ACOUSTIC SIGNAL AND MACHINE-READABLE RECORD MEDIA Russian patent published in 2018 - IPC H04S3/00 G10L19/08 

FIELD: physics.

SUBSTANCE: method for rendering an acoustic signal comprises the steps of: receiving a multi-channel signal comprising a plurality of input channels to be converted into the plurality of output channels; retrieving the elevation rendering parameters for an input altitude channel having a standard elevation angle, such that each output channel provides an audio image having an elevation sense; and updating the rendering parameters for an input altitude channel having a predetermined elevation angle different from the standard elevation angle.

EFFECT: reducing the distortion of the audio image when the elevation angle of the input channel differs from the standard elevation angle of the input channel.
