When using services such as YouTube (registered trademark) and TikTok (registered trademark), use a wireless microphone in addition to a video / audio device (for example, a mobile phone, digital camera, video camera, etc.) to make sound in the optimum state. It was important to collect the sound.

In conventional wireless microphones, the wireless receiver communicates with the video / audio device, and the moderator (for example, influencer, video distributor) often uses the wireless microphone to partition the site, but the image and sound are synchronized. There were problems such as not doing, no sound, a lot of noise, and the moderator forgetting the lines. The reason is that the sound source signal that the wireless microphone sends to the wireless receiver is not monitored synchronously, and if there is a problem with the sound source signal, it cannot be immediately noticed, and eventually the video must be deleted. Sometimes it disappeared, scenes where the audio did not match were broadcast, and embarrassing scenes where the moderator forgot the lines were broadcast.
