I've been doing some restoration work on speech recently and there is a lot of sound from the camera guy moving around and rustling his clothes...most notable in the higher frequencies. Whilst spectral repair can be effective (I'm using RX advanced) I wondered whether there was a kind of dynamic gate, which only lets certain frequencies through once they hit a certain level. This way I could preserve the T's and S's but dim this high frequency rustling through most of the speech. Or, better still, does anyone know of a dynamic EQ which has a 'top' and a bottom threshold setting, meaning you could set it to attenuate frequencies over a certain level, but also to bypass itself after another threshold, (although I'm not sure how this would work for without dipping the beginning of the T's and S's, unless you had the option of changing the pre attack time of the louder transients which cause it to bypass any gain reduction, which obviously wouldn't work in realtime.)
Anyway I'm relatively new to restoration, so your help and advice would be much appreciated!
