FilterCrusher – Free Tube Filter VST/AU Plugin By AudioAssault

By Tomislav ZlaticNovember 15, 201962 Comments2 Mins Read

FilterCrusher is a freeware filter effect VST and AU plugin. It is built on a tube circuit model used in 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 analog 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 further distort the signal, 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.

  The DAW is MuLab 6 (http://www.mutools.com/). A fantastic affordable DAW with tons of modular options “under the hood”. I use it for sound design purposes and it’s my go to plug-in host for live use.

The first time I put this on a bass, it emitted an insanely loud and abrasive buzzing noise. I had to turn my interface off to prevent my monitors from blowing. I am using studio One. I will remove this from my comp and attempt a reinstall. Wish me luck. I have other products by Audio Assault and I haven’t had any problems.

  Excellent plugin but experiencing the same signal overload issue mentioned previously and it completely kills my audio (using Logic Pro X) – hoping there is a bug fix coming for this?

I wish I could use this plugin, but when I add it to a channel in FL Studio, there’s a click/pop and the channel overloads in the red. Is there a fix for this?

  You will need a VST or AU host application such as Logic, for example.

Will there be a fix for the overloading problem in the future? I have installed the most recent version, but when opening in FL Studio (64-bit) it immediately overloads the channel in the red. Can’t use it like this, unfortunately.

I’m still having the issue discussed above with the audio level spikes. Only downloaded two weeks ago. Such a shame cos’ the filter is really smooth when it works and doesn’t feel notched like a lot of soft filters but I nearly broke my ears when it failed.

Great plugin, I use it A LOT! But I’m always very wary to use it because I get the same overload issue others have gotten. I usually have to disable the plugin and reenable it to get it to work. Having this issue in Studio One.

Any chance on a fix on the the audio burst issue? Still installs as version 1.00 and I get a nasty buzz every time I bring it into FL Studio or Maschine

Thanks for a great plugin! At first glance I could not believe that an old plugin from 2014 would do the job so well.

It’s weird, but I was searching for a free LP/HP filter effect for a REALLY long time and couldn’t find one that fits all my needs. As a dj, I got used to have a simple knob on a mixer/controller that acts as a HIcut/LOWcut filter that works smooth and gives you an option to create fading effects by using only one knob (as on Pioneer DJM series). And it should be able to get automated with envelopes (this means that you prefer to see values like 0%-50%-100% for an ease of use).

For some reason, some developers are doing it in a wrong way, so the filters themselves might sound great, but the transition doesn’t work smooth or there are too many parameters you have to tweak at the same time to get the desired tone.

In this case, I’m really happy with FilterCrusher, as it does exactly what I need.

Only things I would improve would be:
– Double click for knob reset (default resonance is 2.31 and you don’t know this value until reset but want to make sure it’s in reset so it doesn’t affect the sound).
– Right click to enter the value.
– A bit bigger input box for values, as 19.000Hz does not fit there. Even 100.00 on input doesn’t fit well.

P.S.: Used in Reaper v6.36, Win10, 1080p.

Other than that it’s great and it looks like I’m going to use it as my main automation filter. Will check all other BPB plugins that I might have missed for some reason.
