Can I use these Sound Effects for free?

Actually I can understand the question.  If you follow the link to the EULAs you get a complex page listing all the various Audition software items separately but with no mention (at least that I can see) of the Sound Effects (or the Loopology music loops for that matter).

However, I can confirm that it's my understanding that the sound effects are available for use in your projects completely royalty free.

As an FYI a site I find very useful for sound effects is Freesound.  Freesound.org - Freesound.org   You have to sign up but it's free and they don't spam you or anything.   You'll even find some of my effects on there, recorded and edited in Audition!  Some of the effects include a request that you credit them at the end of your video but that's a minority.

Lastly, if you are willing to pay a small amount, Sounddogs  Sound Effects Downloads | Sounddogs.com  has the most complete library I know and you pay a relatively small one-off purchase fee with no complicated royaties.
