This is something I plan to implement at the table this weekend… It is a sound mixer that plays out multiple streams at the same time, so imagine:
Music (battle music, action music)
Swords clashing sound effects
Monster Grunts sound effects
Dungeon Atmosphere sound effects
Human grunts sound effects
You have the perfect background music and effects while you are play out an encounter.
Every audio track is loopable, and you can control them independently of each other, so if you get tired of one, turn it off without affecting the others, or bring in another one while the other ones are playing…
mixere.sourceforge.net
It is free open source software. The only thing you have to do is find the audio tracks for it. If you have movie soundtracks, then there you go, rip and go. I have a D&D “Music for Roleplaying” CD I picked up some time ago that’s pretty good.
A good source of sound effects is the MP3 sound effects binaries newsgroup on Usenet. They have on there swords, horses, field nature sounds, dungeon atmosphere, monsters, EVERYTHING!
I have nothing to do with the program, but it was so cool I thought I’d share.
