KR-Fatter STR - the Swiss Army knife of audio transformation

STR is a digital signal processor that operates exclusively in the selected frequency range and makes use of specially developed spectral transforms for synthesis and audio effect design.

At the same time, KR-Fatter STR is using specially designed time domain processing elements like fractal based variance controls. By combining these two platforms in a single unit, new more powerful effects can be achieved by rather using a single platform.

KRFatter GUI

KR-Fatter STR can be used to enhance the spectral content of audio signals containing vocal, instrument or synthesized sound recordings. By using different combinations of the available modules KR-Fatter STR allows the creation of different effects like Fattening, Spectral Coloring, Imaging, Harmonizing, Pitch Shifting, Delay, Modulation and other Special effects. Special attention was given to the design of this processor in the use of Naturally perceived randomization of the available functions in order to produce a spectrally evolving output. These randomizations implemented using Fractal algorithms can transform dull static audio signals into vibrant, rich and natural sounding recordings.


  • Generic pitch-shifter - generate pitch related variations of the original audio signal

  • Animated pitch variation - produce animated pitch variations

  • STR color (STR transform filter) - design thousands of different spectral color variations of the original input audio spectrum

  • Low frequency oscillator - give vibrato effect

  • Phase - add naturally perceived phase related variations

  • Amplifier - add naturally perceived amplitude related variations

  • Shelving equalizer - use to spectrally balance individual channels and/or the whole mix

  • Delay - use to create delayed copies of the input

  • Panning - use to create imaging effects or expansion

System Requirements

  • Windows PC - Intel Core 2 Duo 2GHz, AMD Athlon 64 or higher, Windows 7, 8, 10 or higher
  • Mac OS - Core Duo 2.3Ghz or higher, 10.12.x - 10.14.x or higher
