Alternatively, step 401 may also continuously or periodically detect a camera used by the mobile terminal during the video recording process of the mobile terminal, which is not limited herein.
in the embodiment of the application, the sound channel mode of the mobile terminal can be divided into a mono channel mode and a stereo mode, and in the process of starting video recording or video recording, a user can input a sound channel mode switching instruction through a preset control so as to select or switch the sound channel mode. Specifically, the video recording processing method in the embodiment of the present application may further include: if an input channel mode switching instruction is received during the recording process of the mobile terminal, the channel mode of the mobile terminal is switched to a mono mode or a stereo mode based on the channel mode switching instruction, and step 401 is triggered.

In step 402, when it is detected that the camera used in the recording of the mobile terminal is a front camera in the mono mode of the mobile terminal, the first microphone is triggered to collect the sound signal, so that the sound signal collected by the first microphone is used as the recording of the current recording.
It should be noted that, if the camera used when detecting that the mobile terminal records video in the mono mode of the mobile terminal is a front-facing camera and the first microphone is currently used to acquire the audio signal, it is only necessary to keep using the first microphone to acquire the audio signal.
in step 403, when it is detected that the camera used in the recording of the mobile terminal is a rear camera in the mono mode of the mobile terminal, the second microphone is triggered to collect the sound signal, so that the sound signal collected by the second microphone is used as the recording of the current recording.
It should be noted that, if the camera used when detecting that the mobile terminal records video in the mono mode of the mobile terminal is a rear camera and the second microphone is currently used to collect the audio signal, it is only necessary to keep using the second microphone to collect the audio signal.
Step 404, if it is detected that the camera used when the mobile terminal records the video is a front camera in the stereo mode of the mobile terminal, triggering the first microphone and the third microphone to collect the audio signal;
in step 404, when it is detected that the camera used in the recording of the mobile terminal is a front camera in the stereo mode of the mobile terminal, the first microphone and the third microphone are triggered to collect sound signals, so that the sound signals collected by the first microphone and the second microphone are used as the recording of the recording. Further, the noise reduction processing may be performed on the sound signal recorded in the video recording based on the sound signals collected by the first microphone and the third microphone. Specifically, the noise reduction processing mode may be implemented by referring to a noise reduction processing algorithm of the dual microphones, and details are not described here.
It should be noted that, if the camera used when detecting that the mobile terminal records video in the stereo mode of the mobile terminal is a front-facing camera and the first microphone and the second microphone are currently used to acquire audio signals, it is only necessary to keep using the first microphone and the second microphone to acquire audio signals.
Step 405, triggering the second microphone and the third microphone to collect sound signals if the camera used when the mobile terminal is detected to record the video is a rear camera in the stereo mode of the mobile terminal;
in step 405, when it is detected that the camera used in the recording of the mobile terminal is a rear camera in the stereo mode of the mobile terminal, the second microphone and the third microphone are triggered to collect sound signals, so that the sound signals collected by the second microphone and the second microphone are used as the recording of the recording. Further, the noise reduction processing may be performed on the sound signal recorded in the video recording based on the sound signals collected by the second microphone and the third microphone. Specifically, the noise reduction processing mode may be implemented by referring to a noise reduction processing algorithm of the dual microphones, and details are not described here.
It should be noted that, if it is detected that the camera used when the mobile terminal records the video is a rear camera in the stereo mode of the mobile terminal and the second microphone are currently used to acquire the audio signals, it is only necessary to keep using the second microphone and the second microphone to acquire the audio signals.
It should be noted that, the mobile terminal in the embodiment of the present application may be a mobile phone, a tablet computer, a wearable device, or another mobile terminal with a video recording function. The operating system installed on the mobile terminal may be an ios system, an android system, a windows system, or other operating systems, which is not limited herein.
As can be seen from the above, in the embodiment of the present application, the first microphone, the second microphone, and the third microphone are respectively disposed on the front side, the back side, and the bottom of the mobile terminal, and by detecting the camera used when the mobile terminal records video, when detecting that the camera used when the mobile terminal records video is a front camera and the mobile terminal is in a mono mode, the first microphone is triggered to acquire an audio signal, and when detecting that the camera used when the mobile terminal records video is a rear camera and the mobile terminal is in the mono mode, the second microphone is triggered to acquire an audio signal. Because the recorded object usually faces the front side of the mobile terminal when the front camera of the mobile terminal is used for recording, and the recorded object usually faces the back side of the mobile terminal when the rear camera of the mobile terminal is used for recording, the sound signals are collected by the microphone at the corresponding position triggered by the camera and the sound channel mode used when the mobile terminal is used for recording, the sound signals of the recorded object can be collected more favorably in the recording process, and compared with the scheme that the sound signals are collected by the microphone at the fixed position (for example, the microphone arranged at the bottom of the mobile terminal) in the traditional recording, the scheme of the application can improve the recording effect of the mobile terminal in the recording process to a certain extent.
