Also; can there wreally be copyright on weaponsounds?
Of course! Anything that you create (or in this case, could be 'record') is automatically copyrighted (unless it's a recording of something else copyrighted...). Anything that someone else creates or records is automatically copyrighted by them. I cant wreally play my own sound at home either =)
Of course you can. There are plenty of freeware, shareware sound editing programs. Use them.If you have a microphone, you can make plenty of sounds yourself just with your own body or the things you have around you. I for instance made a slot machine game and needed a sound for the coins dropping into the machine and coins being paid back to the player. I achieved it by recording myself dropping quarters onto a tin can cover. I recorded multiple samples and used the ones I liked.
You can start with a sound like I did above and modify it by using the sound editors features to come up with even more sounds.
If you don't have a microphone, you can still find freeware sounds off of the net, and modify them to your liking.
P.S. wreally is spelled really
