The Cats Meow
This might sound a bit weird, given the fact that I do SEO in a Search Agency but believe it or not, I am interested in search engines. I just found a new one, it needs a bit of polishing but it comes in handy for the amateur film-maker in me.
I was looking for some random animal noises recently and came across this gem of a site, find sounds which does exactly that, it finds sounds. Its not fancy, in fact its very web 0.95, but it works.
Most of the other audio search engines out there are quite horrible and corrupted by MP3's and really bad hip-hop, this is easy to use and delivers. It doesn't work in chrome though, although I believe that is probably chrome's fault, because it works in everything else.
