Being fresh out the gates, my sound library isn't very large, and most of it has a Creative Commons Attribution license. Also, my primary resource for sound effects -- freesound.org -- has the same licensing on most of the community's sounds.
Now, I know using those sound effects outright isn't sound design, and I'd never slap another person's sound effect in my project without manipulating it first, but is it acceptable to use sound effects with an Attribution license in a demo reel?
And, if I do, how would that effect my appearance and reputation as a sound designer? Would I be taken less seriously because I can't afford SFX libraries or mics to make my own?
Finally, if I do use those sound effects, is it kosher to have a link at the end of the reel (like "For Attribution credits, go to mysite.com/democredit"), to keep it short and sweet, or should I fully list all the credits at the end?
