Abstract: M audio signals are obtained by processing an audio signal by M virtual speakers; M first HRTFs and M second HRTFs are obtained, where the M first HRTFs corresponding to a left ear position, and the M second HRTFs corresponding to a right ear position; high-band impulse responses of some of the M first HRTFs are modified to obtain modified first target HRTFs, and high-band impulse responses of some of the M second HRTFs are modified to obtain modified second target HRTFs; a first target audio signal corresponding to the left ear position is obtained based on the modified first target HRTFs and un-modified first HRTFs, and the M audio signals; and a second target audio signal corresponding to the right ear position is obtained based on the modified second HRTFs, un-modified second target HRTFs, and the M audio signals.

Abstract: This application discloses an audio rendering method and apparatus. The method includes: obtaining a to-be-rendered audio signal; determining K first combined HRTFS based on K first HRTFs and K second HRTFs; determining K second combined HRTFs based on K third HRTFs and K fourth HRTFs; determining a first target rendered signal based on the K first combined HRTFs and the to-be-rendered audio signal, where the first target rendered signal is a rendered signal output to the left ear of a listener; and determining a second target rendered signal based on the K second combined HRTFs and the to-be-rendered audio signal, where the second target rendered signal is a rendered signal output to the right ear of the listener.
