Audition greatly amplifying breathing noises for some reason

I've loaded the tracks into Audition and applied no effects or anything to them, just started playback before doing any editing. For some reason the slightest breathing noises are insanely amplified, as if Audition is trying to bring them up to the normal volume of the rest of the track. There's another instance where I have to jack the volume up very high in a regular media player to hear a tiny breath, but in Audition it comes through as a loud pop. None of this is happening in Audacity. I haven't had this happen before and have no idea what's causing it.
