Hello world...Crash Bulb is a collective of ADHD goofs who like to make stuff: music loops, field recordings, little vids, scribbled stories and doodles. We're all fans of FreeSound, and if you're reading this you probably are too.
Most of our sounds are designated "Creative Commons 0", which means you can use them without attribution. But some are licensed as "attribution, non-commercial" which means you're free to use them for non-commercial purposes. If the sound you're using requires a credit you can simply say the sound came "via CrashBulb on FreeSound Dot Org."
It probably goes without saying we do not agree to pack creations of our content being sold commercially. Or any reposting of our content back to FreeSound (or other sound sites) under another name not associated with us. Especially if it goes against the sound's original creative commons license and requests attribution to the unassociated party.
Annnnnnd... of course, we'd appreciate if lovely folks would refrain from registering YouTube content ID numbers for individual items from CrashBulb's FreeSound offerings, as this will discourage others from using the sounds—and create erroneous copyright disputes that we really don't want to be dragged into again.
And with that, we're back to the lab to concoct more shareable content... or resting on a bed of nails until the edibles kick-in. Cheers to you! Thanks for stopping by.
