FilterCrusher is a free dual filter effect built around a tube simulation circuit which is based on Audio Assault’s superb commercial tube amplifier plugin GrindMachine. FilterCrusher was developed by Audio Assault and it is available for free download exclusively on Bedroom Producers Blog. The plugin is released as a 32-bit and 64-bit VST/AU plugin for Windows and Mac.
FilterCrusher features a pair of resonant filters (high pass and low pass) which operate individually. Due to their transparent sound at the lowest resonance setting, the two filters can be used for cleaning up the top and bottom end of audio tracks. At higher resonance settings, they can be used for various creative purposes such as filter sweep effects, boosting certain regions of the frequency spectrum (e.g. adding more thump to bass drums), emulating the frequency response of analogue circuits, etc.
At default settings, the effect of the tube circuit is fairly subtle and almost completely transparent. To add a bit of tube saturation to the processed audio signal, increase the input gain and then lower the output volume to prevent clipping. You’ll hear the effect of the tube emulation algorithm which “warms up” the audio signal and slightly compresses the dynamic range. This kind of effect sounds particularly well on drum loops and it can also add a bit of life to dull synthesizer sounds.
To distort the signal even more, press the CRUSH button which is located in the middle of the GUI. This will boost the volume of the signal on the input, resulting in clearly audible distortion. Use this setting to get more aggressive sounds, or for parallel processing.
The plugin was developed by Audio Assault. Visit their official website if you’re looking for high quality virtual guitar amplifiers at affordable prices.
