Breath sounds being boosted with audio post processing


i'm new recording , i've been working hard try reduce challenges need dealt in post.
here summary of i'm doing far:

  1. i'm using audition cc
  2. i have heil pr40 mic on boom stand foam pop filter. (i have tried double screen type pop filter similar results).
  3. mic places around 8-10 inches away , level of eyes reduce breath sounds
  4. my recording levels aim -12 levels still leave room occasional pops.
  5. i have fair range in tones in voice share stories , may quieter emphasize aspects of story. try minimize when recording though.

 

here's challenge. when process files, find breath sounds becoming far more of issue in master recording. guess levels equally boosts breath sounds. i've tried 2 different ways of processing:

 

  1. speech volume leveler.
  2. single band compressor set threshold of -9 db, ratio of 4:1, attack 2 ms , release of 100 ms. recommended 1 of videos tracked down online.

 

in both cases, seem breath sounds boosted disproportionately voice. love suggestions on simple ways process spoken word. i'm continuing work on improving microphone technique make less necessary. can hear sample of audio in podcasts @ http://www.mountainnature.libsyn.com.

any form of compression, @ all, lead increase in breath noise. it's because you've restricted dynamic range, relative level of breathing sound greater compared 'wanted' sound. on top of that, using mic 8db boost between 1khz , 5-10khz (quite broad boost on mic), , that's going emphasise breath sound more.

 

i don't know how breathing, in general breathing through mouth tends make rather more noise breathing in through nose, although ymmv. may worth try, though...

 

so can't guarantee fix i'm afraid, @ least there's explanation , possible experiment...
