Flandersh Tech GFilter & GGen x64 VST3 WiN [FREE]

Flandersh Tech GFilter is a free 64-bit VST3 filter effect for Windows, paired with GGen, a standalone tool for creating filter impulse responses. It suits hobby producers who want to tidy up instrument tracks or explore more expressive filtering in a mix.

GFilter offers 14 filter types, an impulse response filter and a DC blocker. Delay, creative effects and simple LFO modulation provide options for adding movement and reshaping sounds beyond basic cleanup. A spectrum meter helps you monitor the frequency content while adjusting the processing.

The included GGen application builds 2048-tap impulse responses using four filter types and ten window types. Impulse and spectrum meters help you inspect the results, and WAV export supports up to 32-bit float at sample rates as high as 384 kHz. Example impulse responses are also included for use with GFilter’s IR processor.

The bundle requires Windows 8.1 or newer, the 2015 Visual C++ Redistributable and a legally acquired host with 64-bit VST3 support. It fits compatible Windows setups running FL Studio or Ableton Live; it is not a macOS or Logic Pro release.
