I just know that because there are some stadiums that do not have enough supporters, but the cheers sound already full lively with drum strings also.
what do you think?, is real or use recording through speakers
any chance you can share the video of the highlights you've watched so I can hear for myself? anyway, the only time I've heard of stadium using fake cheers was during the COVID-19 pandemic (which is understandable) but at present maybe they are also using it when there are not many people watching.
