Sounds in iPhone game
Started November 10th, 2009 · 7 replies · Latest reply by astutters 14 years, 11 months ago
I'm an independent game developer (a team of one, actually), and I've recently finished an iPhone game. In this game I use 5 sounds from freesound.org, now here's my question: I am going to charge $0.99 for the game (there will be a free "lite" version that lets you play 2 levels). So, can I use these sounds in my commercial game, as long as I put credits to the sound authors in the "info" section of my game? Should I contact each author and ask them? Or does CC prohibit me from commercial use?
Commercial use is allowed. Technically it isn't necessary to contact the sound creators, but attribution is required. Also, you must make the licensing of the sounds clear in your game, in the credits, for example.
The only limitation is that the sounds cannot be used in any form of advertising (except for the product itself). So if your game is used as part of promotion of anything, it is not allowed to use the sounds (except if the promotion is the game itself, so the Lite version promotes the full version, you are allowed to do this).
And of course you are very welcome to make a donation to the Freesound project 
How make a correct attribution?
I Write in the credits the name of creator sound
and Make a link of the licensing
any more?
For example:
CREDITS:
creators of Sound used in this game:
guitarguy1985
DJ Chronos
and
Kyster
of the www.freesound.org
Under licence: http://www.freesound.org/legal.php
this is the way?
Thank you very much for reply 
Yes, something like that. I personally always add links to the individual sounds too, and actually name the license: "Creative Commons Sampling+ 1.0". People who already know the license then don't have to go over to the license page.
