as a wedding photographer who has been asked to start shooting for web tv I have faced a similar problem.
I edited one episode with laugh tracks and on without laugh tracks.
They opted for the one without. I warned them it would sound kinda phoney, and they agreed….
Now we still added some audience clapping/cheering into the intro and endings…
You’re best bet if you want an audience… is to get them in there. Get real people, even if you have to give something away…. free coffee and donuts or model portfolio head shots or something… or get frineds and family to support you….
