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 a to-be-processed audio signal by M first virtual speakers, and N second audio signals by processing the to-be-processed audio signal by N second virtual speakers, wherein the M first virtual speakers are in a one-to-one correspondence with the M first audio signals, the N second virtual speakers are in a one-to-one correspondence with the N second audio signals, and M and N are positive integers;
• and
• obtain M first head-related transfer functions (HRTFs) and N second HRTFs, wherein all the M first HRTFs are centered at a left ear position, all the N second HRTFs are centered at a right ear position, the M first HRTFs are in a one-to-one correspondence with the M first virtual speakers, and the N second HRTFs are in a one-to-one correspondence with the N second virtual speakers;
• and obtain a first target audio signal based on the M first audio signals and the M first HRTFs, and obtain a second target audio signal based on the N second audio signals and the N second HRTFs.

A non-transitory computer-readable storage medium storing computer instructions, that when executed by one or more processors, cause the one or more processors to perform the steps of:

• obtaining M first audio signals by processing a to-be-processed audio signal by M first virtual speakers, and N second audio signals by processing the to-be-processed audio signal by N second virtual speakers, wherein the M first virtual speakers are in a one-to-one correspondence with the M first audio signals, the N second virtual speakers are in a one-to-one correspondence with the N second audio signals, and M and N are positive integers;
• obtaining M first head-related transfer functions (HRTFs) and N second HRTFs, wherein all the M first HRTFs are centered at a left ear position, all the N second HRTFs are centered at a right ear position, the M first HRTFs are in a one-to-one correspondence with the M first virtual speakers, and the N second HRTFs are in a one-to-one correspondence with the N second virtual speakers;
• and
• obtaining a first target audio signal based on the M first audio signals and the M first HRTFs, and obtaining a second target audio signal based on the N second audio signals and the N second HRTFs.
