hey, if you're looking for a pretty good pro app that's FREE, check out
Spark ME. it's a cut down version of Spark, and it's pretty full-featured.
couldn't you just hook the output from the wireless right into the mic input on the camera, overiding the on camera mic? i occasionaly work for a video prod company, and we ususally do this, or we have a little mixer that hooks on the camera, and get the on camera audio in one channel, and the wireless in another.
