Tonmann has released Tonmann DeEsser, a basic high frequency dynamic processor (de-esser) VST plugin for Windows.

Is called a DeEsser because it’s mainly designed to get rid of „stinging“ sibilants that may occur on vocals after compression or adding a high boost.

It may be used with any host software that can load and use VST2.4/32bit-compatible plugins, tested by the author are Cakewalk Sonar (4, 7), Sony Sound Forge (9) and DirectiXer (2.5).

It should work in 64bit hosts using a “bitbridge”, but this is untested by the author. User-feedback about compatibility (or not) with other host softwares is welcome and very

The plugin has been carefully designed to suppress any artificial or alienated sound that may arise under awkward situations with some other (even some hardware) DeEssers.


  • True independent stereo operation, but also runs in mono mode
  • Wideband and lowpass reduction modes selectable
  • Fully adjustable center frequency and bandwidth of the detection range
  • Adjustable detection threshold to retain the “crisp” sound character of a vocal
  • Look ahead feature for sibilants with short and sharp attacks
  • Adjustable release time
  • Wide-ranging adjustable attenuation for being able to use it before or after a compressor, just like you prefer
  • „What you remove“ listen mode, one actually hears what’s going to be suppressed
  • Two level readouts for optical supervision

Tonmann DeEsser is available for instant download.
