Do you want a muted audio file? What if there is no sound at all when playing? Or is it pure music without vocals? If it is an audio file without sound, I can tell you how to do it yourself:

1. First unplug your microphone (because some microphones will record the sound even if they are set to mute). Then click "Start" - "Programs" - "Accessories" - "Entertainment" - "Audio Recorder".

2. Start recording by clicking the recording button in the lower right corner. Recording for 5 seconds is enough. Of course, if you record too much, you can use the mouse or arrow keys to adjust the position of the slider. After adjusting it, use the two delete commands in the "Edit" menu to complete

3. Click "File" - "Save" (or "Save As"), and then save the file

4. Open the wav file saved above with Qianqianjingting, and click on the file name in the file Right-click, select "Convert Format", select "mp3 Encoder" as the output format, configure it, set the following options according to your own preferences, and then click "Convert Now" below
