Can you offer recorded sounds from games like HALO or any other popular game like Super Mario or Zelda games? I can see how it would be a copyright violation, but then again, I have never heard of anyone getting in trouble over this. If anything, wouldn't I have to put rights to the sounds down on the page of the hosted sound, to stay legal? Thoughts welcome.
If it's very generic sounds like gunfire for example it should be okay. If it's synthesised sound you could have a problem. Bear in mind that someone has still had to make these sounds by fancy electronic gadgetry - if they were so minded they could scream copyright violation.
Can't he use them and mabye at the end or somewhere say "sounds from blah blah etc.." Isn't that legal? As long as you state WHERE and WHO you got/used it from?
I think it could be legal if you ask for permission to take small loops for non-commercial projects that may fall into the fair use of copyrighted works. But taking the content ad libitum and offer such sounds for sale it's obviously a copyright infringement.
NO, that would not be legal. Providing a source doesn't mean that you can break the copyright of the material. You need to have the copyright holder's permission before using the material. Using it without permission is a copyright violation even if you say "Sound from xxxx created by xxxx".
