Soundsnap.com, the free online sound library and community, is now offering sounds from numerous respected sound designers, including Paul Virostek (Million Dollar Baby, Ali, Batman Begins) and Ric Viers, who has created SFX libraries for Apple, Adobe, Sonic Foundry and Hollywood Edge.
I've posted about Soundsnap before. Having recently used them for both an indie feature and handful of short films, I was already impressed with the quality of the tracks and the ease of use. With professionally recorded SFX now being added, Soundsnap should become an essential part of any sound mixer's tool kit, but especially with us indie filmmakers (remember the whole "free" part?).
