I am working with some voice over that will be played quietly in the background, and am finding that even subtle sibilance, the sharp hiss or "ess" sound made when "S"s and "C"s are pronounced, is distracting when played like this.
The DeEsser tool in Adobe Audition is certainly easy to apply and does provide a perceptible improvement at normal listening volume. However, at low volume for background listening it makes no noticeable improvement to the sibilance, and comes with the cost of adversely affecting the sound of the whole VO.
I have found that my best results have come by simply de-amplifying the track at the sibilance spikes. This is very time consuming, and I want to automate it or apply an affect that does this.
Is it possible in Audition, or any piece of software for that matter, to automate the process of finding sibilance spikes then applying an effect only during such spikes? To turn an effect (i.e. multi-band compression) on or off - up or down, as the track plays? Can I find and flag a frequency profile (a sound), then listen for that sound and when it is present, turn on an effect?
Thank you, in advance, for your assistance.
