@atmasphere that is one of the benefits of having the visual aspect of the video. It shows the system being recorded and from what location the recording is being made. Of course someone can always cheat and embed some other audio on the video but what does that gain the person who uploaded or shared a doctored audio recording? Nothing really; as you have seen not many audiophiles value audio recordings when embedded in videos.
People use all types of equipment, like the guy, Josh I believe at Believe in High Fidelity, who is using ultra expensive professional studio microphones and high-end studio equipment to try to get an edge but to me the sound of his audio recordings/videos isn’t that impressive. So not sure the extra time, effort, and expense really gained him that much than if he would have simply made a simple recording with a portable recorder, phone, or camera.
Then you have people like Michael Fremer who will post audio recordings/videos of his system recorded directly from the output of the phonostage. That is not the same as a system’s audio recording recorded from the listening position.
The best way to hear or listen to find out if there is any shenanigans is to listen for the room contributions in the audio recordings because no matter how small they are there is always a slight trace.
People can always find a way to cheat but those that do are only fooling themselves.
