Greetings Austin et al.You can safely assume that 99% of the sounds in swamp are either licensed or are made by myself, and thus not "free" sounds.
Sounds distributed with Swamp carry a per-project license, not an unfettered redistribution license. So while people may obtain them as a part of Swamp, using those sounds in other projects without express permission is going against the regulations.
Don't want to be a party popper at all, I'm just stating the situation as is.
