You're right, 3. doesn't put limitations on derivate works themselves, but 3.a. puts limitations on what kind of derivate works may be created
Re-creativity permitted. You may create and reproduce Derivative Works, provided that:
1. the Derivative Work(s) constitute a good-faith partial or recombined usage employing "sampling," "collage," "mash-up," or other comparable artistic technique, whether now known or hereafter devised, that is highly transformative of the original, as appropriate to the medium, genre, and market niche; and
2. Your Derivative Work(s) must only make a partial use of the original Work, or if You choose to use the original Work as a whole, You must either use the Work as an insubstantial portion of Your Derivative Work(s) or transform it into something substantially different from the original Work. [...]
3.a.1 does apply, 3.a.2 does not apply, if you intend to just cleanup/cut some sounds.
I'll reply in the freesound thread as good as I can as well, since you asked different questions there.
