As a GM, I'm thinking about experimenting and using sound effects to add to ambiance to the game. For example instead of just telling players that a zombie has appeared as they are scavenging in like a mall (for example), I'm just describe the setting, let them explore and as they are "walking" just play a zombie moan soundbite and gauge their reaction as to what to throw at them next. Thoughts? anyone know a good website or app?

I stumbled across this site over the summer. I'm not sure if it was on another board, or on the Geek and Sundry website.

There are a lot of different options on the site including a zombie one as well.

Thanks! That provided just what I was looking for. I shared it with friends
