T-De-Esser

This is a very good de-esser plugin. Last time I had to deal with live recorded (by a dynamic mic) Rock vocal tracks with huge sibillance issues - 2-hours performance, so I decided to not de-ess manually.
T-De-Esser was finally chosen with a two other de-esser plugins - Weiss Deess and PSP InfiniStrip de-esser module and all three were used in this vocal track's production chain. Some other de-ess plugins from known developers did not pass the test in this particular case.
T-De-Esser was placed first in the main track chain, before compression/EQ and did the job perfectly. I used it also before a voc-reverb on a send channel.
It is a high-end quality, smoothly sounding de-esser and it's free. Since I have it, I use it regularly also for taming/controlling open hi-hat type of sounds.
