Audio debugging course

When testing the sound, you can adjust the buttons slightly in the range of 20-20KHz, and constantly record the voice comparison of the volume of each node. Under the rated sound, you can debug the equalizer, different people have different habits of the sound color of the music, and you can adjust it to the appropriate level according to their hobbies.

Microphone testing is also a key step. There are two types of microphones: wired and wireless. You need to set the corresponding frequency modulation channel, and different channels correspond to different microphones. You can start to modulate from a low voice, and gradually improve your own voice and make records.
