Freesound Forums

I'm currently in the process of making a game, which I hope to upload to play for free on various sites such as Kongregate and NewGrounds. I stumbled across this site when looking for sound effects to include in my game, and would like to clarify an issue I have.

Several of the sounds I am interested in are classed as "attribution noncommercial", which after following the relevant links, reveals "you may not use the material for commercial purposes".

My dilemma is that while I wish to distribute my game completely for free (I'm making the game for love of the craft, not financial benefit), sites such as Kongregate automatically place adverts onto uploaded games and give the uploader a small percentage of earnings, regardless of whether they want to or not.

To my knowledge this cannot be avoided (although if you know of a way I'd love to hear it).

Basically my question is, if I use a sound from this site that is licensed under "attribution noncommercial" and put it into a game that I upload onto a site such as Kongregate, would I therefore be breaking the agreement (when considering any earning would be both minuscule and unwanted)?

I'd really appreciate if you could help clear this up. Obviously I don't want to piss off any content creators or break the law, I just simply want to make a good game.

Ask the individual contributors.
I have had several people approach me regarding this very issue (for stuff I have posted here as well as ccMixter.org).
To me, there is a distinction between incorporating "attribution noncommercial" work into a creative endeavor that happens to bring a miniscule amount of financial gain to its creator (for example, an indie game) and using it in service of a product specifically designed to be mass produced and sold on a large scale.
I am always happy to contribute to someone's creative endeavor, and no doubt, many other freesounders feel the same.

Thanks for the response.
I'll be sure to message content creators when I get around to choosing sounds.
