Okay, for my rpg I want different music to be looped depending on where you're at. Town Music (maybe different for each town O.o???) Cave Music, Temple Music, etc. etc. But I've come to a problem and want to find out if it's the ONLY solution. My problem is how do you stop a longer loop from blending into the next .wav. Or do you have to dissect the original sound file into one second parts and then use death counts to make it work? I was desperately looking for a trigger to kill all .wav's being played, but came to an epik Fail.

I've never really used sounds in my maps, and with hyper triggers it could be interesting...

The next step is where I'm going to take music from, but that can come later...

There aren't any actions that stop a playing wav. Solution most people use you already listed. Incidentally that takes care of any problems with wavs playing if someone pauses the game.

Awesome. Any tools (Free) that you use to dissect the sounds?

I think windows Sound Recorder can do it, Audacity definitely can.

Or just google Wave pad, its a trial version, but its free and unlimited. You can do all sort of things with it; cut sounds, add new sounds to another to make an ultimately complete wav, you can even change the quality, so you can have a really nice wav.
Only downsides are missing features (since it is trial, but you won't need em, theese are for cracks) and the fact that you MUST copy the sound on the desktop, caus its too stupid to open shortcuts.

EDIT:
I Didnot saw your last line, i've gathered lots of wavs with years, and i have some town musics i could give you.

Yeah, Audacity is open source, and many more people use it. Changing the quality only makes the sound worse, however.

Side note: Newgrounds has some awesome music .. =o

Yea, there is a lot of music that would be suitable for games on Newgrounds. Look for tracks with the music loop icon.

Okay, so if I have a sound running and a trigger starts an other one, the 2nd will simply play over the 1st as the 1st keep playing?

Yes, this is why people break the wav up into smaller sections and play them based on a timer.

Timer and BRING condition, so that the player won't hear the wav 30 seconds after leaving town.
