I was filming an interview where I was using my Tascam DR-40 to record from a Sennheiser e835 wireless handheld mic. It wasn't an ideal situation, and I had to leave the mic a few feet away from the subjects being interviewed. And now, I'm dealing with the hiss that is common from these kinds of audio recorders.
I'm using Audition CC, and I know how to use the hiss reduction tools available, but I had a thought. I have the in-camera audio from a Rode video mic that I was using. I'm wondering if I can use the relatively hiss free (but with echo) audio from the camera as an audible difference mask (in Photoshop terms) to map good sound from the Tascam. It's a little crazy, but I'm wondering if anyone's done this or could have a way of trying it.
Thanks!
