In terms of software, you can use the player that comes with Windows or various popular video playback software (such as Hero, Oriental Film Capital, etc.). ). The operation steps are as follows: Plug in the microphone, enter the operating system, right-click the volume icon in the taskbar, and select Open Volume Control. After opening, select Options-Properties-Recording-Microphone (with tick)-OK. Then in the "Volume Control" dialog box, remove the tick on "Mute" of the microphone, adjust the volume of the microphone to a moderate level, turn the balance sliders of "Volume Control" and "Waveform" to the left, and then close the dialog box, and everything will be fine.
