1. Re: Hiss removal
Bob Howes Nov 12, 2013 7:39 PM (in response to mattslote)I've never tried that but I wouldn't be hopeful. To continue your Photoshop analogy, the echo on the camera feed makes that recording equivalent to a blurry picture, not ideal for a "difference mask".
I'd give the Audition Noise Reduction a try (and that's not a typo...try noise reduction, not hiss reduction). Do your processing in several light passes rather than trying one big one--and adjust the FFT size upwards for each new noise sample. Generally, that can do an excellent job on hiss.
(As an aside, I've never had a hiss problem with Sennheiser wireless--I don't know the Tascam recorder you used but I'm surprised if it put in a noticeable hiss. It might me time for some system testing and line up.)

2. Re: Hiss removal
mattslote Nov 12, 2013 9:51 PM (in response to Bob Howes)I had fiddled with noise reduction, but I hadn't thought to try it in several passes. I'll give it a shot.
The Tascam is a handheld audio recorder, very similar to the more popular Zoom H4n. They're battery powered and the built in preamps are known to cause a slight hiss. Not a problem if input levels are in normal ranges, but I wasn't getting a lot of signal.

3. Re: Hiss removal
mattslote Nov 26, 2013 2:38 PM (in response to mattslote)Just an update on the hiss situation. Bob, you nailed it with the noise reduction suggestion. A couple passes with that and the hiss is reduced to a workable level. Thanks a ton for the advice, this is a huge help now and I'll be putting it to the test quite a bit in the future.

Bob Howes Nov 28, 2013 2:10 AM (in response to mattslote)Thanks for coming back with your report...all too often we never hear about the successes!
(And to put a personal point on it, when I first saw your response I happened to be in hospital after major surgery--home a couple hours ago--and you made my day!)
