Method and apparatus for separating audio signal, device, storage medium, and program

An electronic device, comprising:

• a processor and a memory;
• wherein the memory stores computer-executable instructions;
• and
• wherein the processor executes the computer-executable instructions, to cause the electronic device to:
• determine first amplitude information of a mixed audio signal to be processed and first phase information of the mixed audio signal, wherein the mixed audio signal is formed by mixing single audio source audio signals corresponding to a plurality of audio sources;
• process the first amplitude information and obtain amplitude difference information and phase difference information between the mixed audio signal and a first audio signal, wherein the first audio signal is a single audio source audio signal corresponding to a first audio source in the mixed audio signal;
• and
• determine the first audio signal according to the first amplitude information, the first phase information, the amplitude difference information, and the phase difference information;
• wherein the computer-executable instructions that cause the electronic device to process the first amplitude information and obtain the phase difference information between the mixed audio signal and the first audio signal also cause the electronic device to:
• process the first amplitude information to obtain real portion information of a phase and imaginary portion information of the phase;
• and
• determine the phase difference information based on the real portion information of the phase and the imaginary portion information of the phase.

A non-transitory computer-readable storage medium, storing computer-executable instructions that, when executed, cause a processor to:

• determine first amplitude information of a mixed audio signal to be processed and first phase information of the mixed audio signal, wherein the mixed audio signal is formed by mixing single audio source audio signals corresponding to a plurality of audio sources;
• process the first amplitude information and obtain amplitude difference information and phase difference information between the mixed audio signal and a first audio signal, wherein the first audio signal is a single audio source audio signal corresponding to a first audio source in the mixed audio signal;
• and
• determine the first audio signal according to the first amplitude information, the first phase information, the amplitude difference information, and the phase difference information;
• wherein the computer-executable instructions that cause the processor to process the first amplitude information and obtain the phase difference information between the mixed audio signal and the first audio signal also cause the processor to:
• process the first amplitude information to obtain real portion information of a phase and imaginary portion information of the phase;
• and
• determine the phase difference information based on the real portion information of the phase and the imaginary portion information of the phase.
