BrAd,
Yes, you are looking for a NOISE GATE. You set a threshold and levels above the threshold will open the gate, everything below the gate will stay closed. You then fool around with attack and release to fine tune it.
The tricky part is if the breath sounds and the voice are too close in level, you will snip off parts of the words as you mention. The only sure way to do it is cutting one breath at a time.
I have found the COMPANDER setting in Dynamics (I think – I’m not at my audio station at the moment), works well for small breath sounds. It COMpresses the voice and raises the level, while exPANDing (pushing down toward 0) the quieter sounds, thus the name COMPANDER.
Have fun!
