    The FULL name is "envelope following filter", that is, a filter that follows the amplitude envelope of the signal.

    The technology (and name) comes from synthesizers. In synths, you can use envelope following circuits to control things other than filters (vibrato or pitch for example).

    And, the BassBalls is a twin envelope filter and has a distortion circuit as well.

    I think the BassBalls is a twin dynamic filter, or is that just a different name for the same thing?

    Twin dynamic envelope follower. As described on the ehx website.
