I like it a lot. Since it is the only free filter vst i know which does such a huge 384 dB/Oct cut. But it is dangerous! if you twist the knobs when the left and right filters are not synced it will cause terrible subbass noise capable of killing your speakers (didnt happen to me). so you better bypass it and set the desired values and the repower it. if you dont mind the fact that it can burst your speakers then it is a very usefull tool.
thanks to the developer!!!
the user interface is well designed friendly to the eye and tatally suficient.
the sound is allright to good.
the features are just right.
i had no look at the doc so i leave that out
i didnt check the costumer support
value for money - priceless
stabilty: well it didnt crash once, but the fact that it cann tear your valuable monitors apart gives it a big minus there
"Rubberfilter offers four classic filter modes to cut frequencies with up to 384 dB/Oct. It removes frequencies in any audio signal, while providing an additional creative purpose. Rubberfilter has a controllable filter order of 6 dB/Oct up to 384 dB/Oct. At high filter order levels, a psychoacoustic effect appears which is usually an unwanted sound of zips and sweeps, almost as if there is a tone present at the filter's cut-off frequency. Rubberfilter allows you to use this psychoacoustic effect for creative purposes."
this psycho effect is very usefull. create a synth melo and set the filter to lopass 384 db/oct around 120hz and you know what i mean ....
