Who has watched it, live?

If you go to battlebot's youtube channel they have battles with just the box audio.

I think it's almost toned down when they mix in the other audio.

There used to be a "gym" just outside Pittsburgh maybe 15 years ago. Went twice and it's as loud and as terrifying as it looks.

We got to see Son of Wyochi and nightmare.

Never been to one live but it doesn't sound like they added an audio affects. But I guess I can't really be sure. I hope they don't

I watched one of their events in 2005. Was a minor event but it has some pretty good fights. Such as the fight where Shrederator throws Redrum into the wall. By the way the pulverizers are extremely loud.
