Engineers Filter

4.3 / 5     (26 votes)
Engineers Filter is a filter plugin that allows for extremely steep filtering.

It achieves this by implementing high order IIR filter design methods that are commonly used in science and engineering, namely Butterworth, Chebychev, inverse Chebychev and elliptic (aka Cauer) filters.
Each of these filter design methods can be applied to create:
  • lowpass
  • highpass
  • bandpass
  • bandreject
  • high/low shelving
  • peak/dip filters of orders up to 20

I´m a great fan of "EasyQ" but now I discovered "Engeneers Filter" for me. I´ve seen a great tutorial about equalizing amp-sims: In this tutorial the harsh and fizzy frequencies were filtered with the brickwall-highcut-function of the expensive "F*bf*lter" in a very impressing way. And "Engeneers Filter" can do that nearly in the same way! I´ve made a test with "VST-PluginAnalyser": With an extreme steep, all the high-frequencies at a selected point were filtered out without effecting the rest of the signal (e.g. an amp-sim-track). So many thanks to Robin Schmidt!

Sorry for necro commenting this old post, but using very steep filters like this on distorted guitars (whether it's amp sims or real amps) can easily get very nasty. Super steep filters have A LOT of ringing to them! Use 18dB/oct or 24dB/oct filters for low- and high-passing (preferably of Butterworth type) to get a more natural sound that still is cutting away unwanted frequencies.

This and other of their products is really great. Simple, effective, not heavy

RS-MET has recently released a VST/AU called ToolChain. It is 64-bit, free and acts as a bundle/shell for several effects created by the developer, including Engineers Filter. You can download from developer's website.

Excellent steep filter! To control/automate parameters in FL Studio, you can use 'MIDI Out' to send MIDI CC messages. In more detail: 1.) In the FL Studio Wrapper of EngineersFilter (EF): Set a MIDI input port (e.g. 10). 2.) In the FL Studio Channel Rack: Create a MIDI Out channel and match the Port number to the one previously selected (here: 10). 3.) In the MIDI Out: Right-click one of the round knobs and choose 'Configure' in the drop-down menu. Fill in name and short name, and set the CC number in the 'Controller' field to an unassigned number (e.g. CC 23), then click 'Accept'. 4.) In EF, right-click on the parameter you would like to control via MIDI CC (e.g. Frequency) and choose 'MIDI Learn' from the drop-down menu. 5.) Immediately thereafter, switch to the MIDI Out and use your mouse to move the round knob you assigned in Step 3 (here: MIDI CC 23). This will automatically link this knob to the chosen parameter in EF, i.e. moving the round knob in MIDI Out will now change the assigned value in EF. 6.) Repeat procedure for other parameters, using different MIDI CC numbers. 7.) Optional: After right-clicking once more on a round knob in MIDI Out, link it to your hardware controller or assign an automation clip as described elsewhere.

High pass filters do NOT work properly. I can't achieve more that 16dB atennuation. Low pass works OK. Tested with Reaper

Can we get an 64bit one ? :)

the mouse brought us all here. only 32 bit? no worries us producers have our ways of getting this to work on 64 bit :D

If you've noticed a spike in downloads it's because Deadmau5 just recomended this plugin on a razer music video :P

I'm so confused. I extract all of the files to my plugin folder in Ableton and nothing is showing up! I've tried closing out of Ableton and loading it back up and still nothing. Can someone please help me?

This is a "32 bit- plugin" . Maybe you own a relative new 64 bit- ableton- version. Then you'll need a 64 bit converter like "j- brige" for this plugin (and all the other fine 32 bit- plugins around the world). Hope that helps...

Is there any other way to get parameter controls besides the sliders on the gui? Otherwise, this is a really extensive and intense free filter vst

Its a good filter yes, but occasionally drives my CPU up to 100 while idle. I'm not sure why, happens in Cubase 7.5.20 and Ableton 9.1.1

I have this problem when I have over ~3 instances running at once in FL 12.0.2

In FL, turn on smart disable. Also how does ableton now have 32 bit support? what year is it?

Smart disable doesnt fixes it at all. And live does support 32bit plugins

anybody figure this out yet? love the plugin but the 100% cpu at idle issue drives me nuts...

This is an awesome filter. Excellent for experimental sound design, and the customization is really nice. Also freaked me out a bit when I noticed my last name is one of the filter modes (Butterworth). My only problem with it is that I couldn't seem to find any way to MIDI map/automate the controls in FL Studio. Anyone got any suggestions?

Ehmm, what about "last tweaked" button in "tools" menu?

Awesome filter. Just what I was looking for. Just a tip, if you want to use specific frequencies, not just what you can drag the slider to, you can save your filter, edit the preset and reload it.

Damn, this is super useful for mixing. Want more headroom? Try high passing things with this. The only way you'd tell it was free was just by the way you dial up the numbers. Other than that, really quality stuff.

best free filter hands down. it has elliptic and butterworth filters with sharp edge cutoff which are the best for getting rid of unwanted noise and frequencies. 5 out of 5
