Audio processing method and apparatus

An audio processing apparatus, comprising:

• at least one processor;
• and
• a memory storing computer executable instructions for execution by the at least one processor, wherein the computer executable instructions instruct the at least one processor to:
• obtain M first audio signals by processing an audio signal by M virtual speakers corresponding to the M first audio signals respectively, wherein M is a positive integer;
• obtain M first head-related transfer functions (HRTFs) corresponding to the M first audio signals respectively from the M virtual speakers to a left ear position;
• obtain M second HRTFs corresponding to the M first audio signals respectively from the M virtual speakers to a right ear position;
• modify high-band impulse responses of a first quantity of 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;
• modify high-band impulse responses of a second quantity of 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;
• obtain, based on the first quantity of first target HRTFs, the third quantity of first HRTFs, and the M first audio signals, a first target audio signal corresponding to a current left ear position, wherein the third quantity of first HRTFs are HRTFs other than the first quantity of first HRTFs in the M first HRTFs, a sum of the first quantity and the third quantity is M;
• and
• obtain, based on a fourth quantity of second HRTFs, the second quantity of second target HRTFs, and the M first audio signals, a second target audio signal corresponding to a current right ear position, the fourth quantity of second HRTFs are HRTFs other than the second quantity of second HRTFs in the M second HRTFs, and a sum of the second quantity and the fourth quantity is equal to M.
