BINAURAL AUDIO PROCESSING Russian patent published in 2018 - IPC H04S1/00 G10L19/00 

FIELD: means of communication.

SUBSTANCE: invention relates to communication equipment and is intended for binaural audio processing. Audio renderer comprises a receiver receiving input data comprising early part data indicative of an early part of a head related binaural transfer function; reverberation data indicative of a reverberation part of the transfer function; and a synchronisation indication indicative of a time offset between the early part and the reverberation part. Early part circuit generates an audio component by applying a binaural processing to an audio signal, where the processing depends on the early part data. Reverberator generates a second audio component by applying a reverberation processing to the audio signal, where the reverberation processing depends on the reverberation data. Combiner generates a signal of a binaural stereo signal by combining the two audio components. Relative timing of the audio components is adjusted based on the synchronisation indication by a synchroniser which specifically may be a delay.

EFFECT: technical result is to provide enhanced sound quality by enabling control of synchronisation of reproduction of various parts from the encoder side.
