I am currently editing a short film that uses a bunch of free sounds. I am only using sounds that are under the attribution or zero licenses just in case I want to use the film commercially or whatever. I was going to use this sound until I saw it was under a sampling plus license:
I later saw these two sounds which are remixes of the sound but have attribution licenses:
Are people allowed to change the license to a less restrictive one when they remix a sound? If so, couldn't you just slightly change the pitch on any sampling plus sound and say you remixed it, and then use it for commercial purposes? I am wondering because I am using some other sounds which are remixes but do not mention the sounds originally used. Thanks.
I'm not a lawyer, but the CC code does suggest the original license is supposed be be maintained unless the original author says the change is OK. It is possible that the remixes were made after Freesound changed the licenses that were available (moving from FS1 to FS2) so the remixes are under the closest one available. Of course all of this is mainly based on the honor system and hoping that people will do the right thing.
But I also would like to mention that using sounds from Freesound in a movie or something else that will make you money is not considered to be using the sounds commercially. The non-commercial aspect is more like you can't use a sound of someone drinking in a beer commercial.
The main thing is being able to attribute the sound to the original author in a reasonable way.
Ok thanks for clearing that up.
"The main thing is being able to attribute the sound to the original author in a reasonable way."
This is another thing I was wondering about. When you use a remix, do you have to mention both the person who did the remix and the original author? Or at least if the original author is mentioned?
