Very poor audio/ sound in this video by presenter. Kindly rectify it.

Dear friend. This video was compiled by a professional team from Russia using my original videos. I just listened to several portions of the video and can't find any problems with the audio. Maybe you had a bad connection or some other problem. You can try later, or you can just select CC so you could read the captions. Good luck.
