Audio processing method and apparatus

A terminal device, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor, when executing the computer program, enables the terminal device to perform the following steps:

• displaying, a first interface, wherein the first interface comprises:
• a control for enabling recording;
• when the terminal device receives an operation on the control for enabling recording, displaying, a second interface and obtaining a first audio signal, wherein the second interface comprises a first picture and a second picture, the second picture is overlaid on the first picture, and the first picture comprises content in the second picture, and the second picture comprises a target object;
• performing, sound source separation on the first audio signal to obtain N channels of audio signals, wherein N is an integer greater than or equal to 2;
• and
• generating, a first video and a second video, wherein
• the first video is obtained based on the first audio signal and the first picture, when the N channels of audio signals satisfy a preset condition, the second video is obtained based on the N channels of audio signals and the second picture, a second audio signal corresponding to the second video is obtained by processing a target audio signal in the N channels of audio signals and/or a signal other than the target audio signal in the N channels of audio signals, and the target audio signal is an audio signal of the target object,
• wherein when the N channels of audio signals do not satisfy the preset condition, the second video is obtained based on the first audio signal and the second picture, and
• wherein that the N channels of audio signals do not satisfy the preset condition comprises:
• that energy of any one of the N channels of audio signals is greater than an energy threshold, and angle variance corresponding to an angle of the any audio signal within a time threshold is greater than a variance threshold;
• and/or
• that the energy of the any audio signal is greater than the energy threshold and correlation of the any audio signal with another audio signal in the N channels of audio signals is greater than or equal to a correlation threshold.

A non-transitory computer-readable storage medium, comprising instructions, wherein when the instructions are run on a terminal device, the terminal device is enabled to perform the following steps:

• displaying, a first interface, wherein the first interface comprises:
• a control for enabling recording;
• when the terminal device receives an operation on the control for enabling recording, displaying, a second interface and obtaining a first audio signal, wherein the second interface comprises a first picture and a second picture, the second picture is overlaid on the first picture, and the first picture comprises content in the second picture, and the second picture comprises a target object;
• performing, sound source separation on the first audio signal to obtain N channels of audio signals, wherein N is an integer greater than or equal to 2;
• and
• generating, a first video and a second video, wherein
• the first video is obtained based on the first audio signal and the first picture, when the N channels of audio signals satisfy a preset condition, the second video is obtained based on the N channels of audio signals and the second picture, a second audio signal corresponding to the second video is obtained by processing a target audio signal in the N channels of audio signals and/or a signal other than the target audio signal in the N channels of audio signals, and the target audio signal is an audio signal of the target object,
• wherein when the N channels of audio signals do not satisfy the preset condition, the second video is obtained based on the first audio signal and the second picture, and
• wherein that the N channels of audio signals do not satisfy the preset condition comprises:
• that energy of any one of the N channels of audio signals is greater than an energy threshold, and angle variance corresponding to an angle of the any audio signal within a time threshold is greater than a variance threshold;
• and/or
• that the energy of the any audio signal is greater than the energy threshold and correlation of the any audio signal with another audio signal in the N channels of audio signals is greater than or equal to a correlation threshold.
