Problems solved by technology
[0002] Stereo sound refers to sound with a stereo effect. In order to achieve stereo recording, it is generally necessary to set at least two microphones on the terminal to obtain the sound of the sound source in different directions to synthesize stereo sound. However, due to the small size of the terminal, the terminal set Less variance in microphone placement in space, less stereo recording

This application provides a recording method. The recording method includes acquiring the first audio signal, the second audio signal and the third audio signal respectively collected by the left-ear earphone, the right-ear earphone and the microphone of the terminal; Signal transmission time synchronization of the first audio signal, the second audio signal and the third audio signal; and according to the synchronized first audio signal, the second audio signal and the third audio signal Synthesize stereo audio signals. In the recording method of the embodiment of the present application, since the position difference between the left earphone, the right earphone and the terminal is generally large, the stereo recording is better, and the first audio signal and the second audio signal obtained by the left earphone and the right earphone The sound field is more suitable for the human ear. The present application also provides a recording device, a terminal and a non-volatile computer-readable storage medium.
Description
technical field [0001] The present application relates to the technical field of recording, in particular to a recording method, a recording device, a recording system and a non-volatile computer storage medium. Background technique [0002] Stereo sound refers to sound with a stereo effect. In order to achieve stereo recording, it is generally necessary to set at least two microphones on the terminal to obtain the sound of the sound source in different directions to synthesize stereo sound. However, due to the small size of the terminal, the terminal set There is less difference in the position of the microphones in space, and stereo recordings are less effective. Contents of the invention [0003] To this end, the embodiments of the present application provide a recording method, a recording device, a recording system and a non-volatile computer storage medium. [0004] The recording method in the embodiment of the present application includes acquiring the first audio ...
