Audio processing method and apparatus

An audio processing apparatus comprising:

• one or more processor;
• and
• a memory configured to store computer executable instructions, wherein the computer executable instructions when executed by the one or more processors cause the audio processing apparatus to:
• receive a bitstream;
• decode the bitstream to obtain a to-be-processed audio signal, wherein the to-be-processed audio signal is an Ambisonics signal;
• process, by M first virtual speakers, a to-be-processed audio signal to obtain M first audio signals, wherein the M first virtual speakers are in a one-to-one correspondence with the M first audio signals;
• obtain M first head-related transfer functions (HRTFs), wherein the M first HRTFs are centered at a left ear position, and wherein the M first HRTFs are in a one-to-one correspondence with the M first virtual speakers;
• and
• obtain a first target audio signal based on the M first audio signals and the M first HRTFs.

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

• receive a bitstream;
• decode the bitstream to obtain a to-be-processed audio signal, wherein the to-be-processed audio signal is an Ambisonics signal;
• process a to-be-processed audio signal by M first virtual speakers to obtain M first audio signals, wherein the M first virtual speakers are in a one-to-one correspondence with the M first audio signals;
• obtain M first head-related transfer functions (HRTFs), wherein the M first HRTFs are centered at a left ear position, and wherein the M first HRTFs are in a one-to-one correspondence with the M first virtual speakers;
• and
• obtain a first target audio signal based on the M first audio signals and the M first HRTFs.
