A while back I linked a gaming site that had various MMO soundtracks you could download. They had a pretty nice selection and found a few tracks that would work well for some background music to my sessions. I used to shy away from having music for my games. However I found with a decent mix you could get something playing in the background on a loop adding a little flavor to the game, and still not make it a distraction to what was happening around the table.
A few months ago I ran a Savage Worlds game for a local con. Being a demo game with new people, I really wanted to add something to the session to make it stand out. Normally I’m not one for sound effects. However for a few key points in the game, I wanted to add something to make it more of an engaging experience. As it was a horror sci-fi game, I also wanted some type of ambient noise to get everyone in the mood. Having a MP3 player and a miniature speaker, I could easily get something portable up and be able to play some tracks without it being too fiddly and taking up a bunch of space on the table.
So I needed to try and pick up some sounds. I stumbled across Freesound.org and fell into the rabbit hole of creative commons sound files. A bit of digging and I was able to find that perfect space ship alarm. There were tons of industrial and factory sounds. You can really find some wonderful ambient stuff. As for my sci-fi horror game, I settled on a few and also threw in a particularly longer ambient music track that was perfect for setting the mood.
The tracks are free, but many require attribution if being used in other projects. Consider throwing a bit of money to the site also as a donation. There are some nice tracks folks have made available. As for me, I am certainly going to be mining this for certain games. I simply cannot see running a horror game taking place on a dark and stormy night without using this site for some needed atmosphere.
