Short answer, no, unless you have the correct licenses for all soundpools from Magix/Catooh that you have used. Check their site and look up all of the licenses that you have vs all of the soundpools that you have used. I presume that you have registered with Catooh. Even then, there are a couple of categories of pro licenses and you have to check them. You can consult directly with Magix about all of this, as we are not lawyers, and you may want to consult with your lawyer. Make sure that you are not using one sound by itself, as you are supposed to be creating an artistic work, not just playing a soundpool by itself. Ideally, you should be adding your own original work to the soundpools.
