Variable Speed Playback enables playing audio at an increased speed. This is a joint development effort with Aocate and requires the purchase of an Android media library called Presto.
This feature is at an EXPERIMENTAL stage. It may work great, crash, or go away in a future release.
I do encourage you to try it...you might find yourself with some extra free time, or at least the ability to listen to more podcasts. It can be enabled in the DoggCatcher Preferences/Audio.
