Hiss removal

i filming interview using tascam dr-40 record sennheiser e835 wireless handheld mic. wasn't ideal situation, , had leave mic few feet away subjects being interviewed. , now, i'm dealing hiss common these kinds of audio recorders.

 

i'm using audition cc, , know how use hiss reduction tools available, had thought. have in-camera audio rode video mic using. i'm wondering if can use relatively hiss free (but echo) audio camera audible difference mask (in photoshop terms) map sound tascam. it's little crazy, i'm wondering if anyone's done or have way of trying it.

 

thanks!

i've never tried wouldn't hopeful.  continue photoshop analogy, echo on camera feed makes recording equivalent blurry picture, not ideal "difference mask".

 

i'd give audition noise reduction try (and that's not typo...try noise reduction, not hiss reduction).  processing in several light passes rather trying 1 big one--and adjust fft size upwards each new noise sample.  generally, can excellent job on hiss.

 

(as aside, i've never had hiss problem sennheiser wireless--i don't know tascam recorder used i'm surprised if put in noticeable hiss.  might me time system testing , line up.)
