Yes. Soundsnap is totally free and allows you to use sounds submitted by users for virtually anything.
Completely free, use for all. Just about the only thing not allowed is: the sounds as such, either individually or as a collection pass.
Yes. This is clearly agreed by users uploading their sounds in the terms and licenses and by the Soundsnap license.
Yes, synonymous commercial use, the men have agreed to their sounds have been uploaded.
You are free: - To remix or transform the sounds in any way - To copy, distribute and transmit the sounds - To use the sounds in any music, film, video game, website etc. whether commercial or not, without paying royalties or other fees
in spirit and not literally, it is you are free to the sounds in all possible variations to modify it to copy, distribute (Caution: not for sale!), or send these sounds in all the videos (and a lot of other productions) to use, whether commercial or not, and for free. BG Andreas
