Classification: CPC H | IPC H

Claim 7:
8. An apparatus for processing audio signals, comprising:
at least one processor; and
one or more memories coupled to the at least one processor and storing programming instructions, which when executed by the at least one processor, cause the audio signal processing apparatus to:
obtain M virtual speakers corresponding to a three-dimensional space, wherein the M virtual speakers include a first virtual speaker and a second virtual speaker, wherein M is a positive integer;
obtain M audio signals by processing an audio signal by the M virtual speakers, wherein the M audio signals includes a first audio signal corresponding to the first virtual speaker and a second audio signal corresponding to the second virtual speaker;
obtain M first head-related transfer functions (HRTFs) comprising a third HRTF corresponding to the first audio signal transmitted from the first virtual speaker to a default left ear position;
obtain M second HRTFs comprising a fourth HRTF corresponding to the second audio signal transmitted from the second virtual speaker to a default right ear position;
modify high-band impulse responses corresponding to a first quantity of the M first HRTFs to obtain a first quantity of first target HRTFs, wherein the first quantity is not less than 1 and not greater than M, wherein the first quantity of the M first HRTFs comprise the third HRTF;
modify high-band impulse responses corresponding to a second quantity of the M second HRTFs, to obtain a second quantity of second target HRTFs, wherein the second quantity is not less than 1 and not greater than M, wherein the second quantity of the M second HRTFs comprise the fourth HRTF;
obtain, based on the first target HRTFs, a first target audio signal corresponding to a current left ear position; and
obtain, based on the second target HRTFs, a second target audio signal corresponding to a current right ear position.
