Hi
Thank you for your update and reply.
First, I would like to deliver my apologize because I think I have some misunderstanding in my last reply. And after I carefully discussed your case with my colleagues. We found that the problem you meet is because your microphone record not only your voice but also the voice from speaker. Please allow me explain that:
- The “record slide show” only can set a microphone to record your voice, but not from system sound, that is expected. Because the “record slide show” needs to record your voice. Your voice will be recorded through the microphone and your voice will be saved as an audio file on the slide. See the screenshot below.
2.However, if you are not using a headphone or like mobile ear phone, your webcam microphone can also record the voice from speaker while recording your voice. In this scenario, if you click the audio file I mentioned above, you can hear the low quality mixed voice. It will play together with the video when you “slide show”.
- so if you want to solve it For this problem, you may need to use a headset to prevent the sound of this video from mixing into your voice when you are speaking. Then you will hear “only the voice from video” and “your speak voice from microphone”. Both of them will be clear
4.However, if you are in a meeting and need to show this video loudly with a speaker, you can only reduce the volume of the video as much as possible.
Unfortunately, this may be the working principle of this function. It seems that there is no particularly good way to meet your requirements. Your understanding is greatly appreciated.
Best Regards
Ethan
