By Tomislav ZlaticJanuary 25, 202177 Comments4 Mins Read

Bedroom Producers Blog is proud to release BPB Dirty Filter, a freeware tube distortion effect in VST, VST3, AU, and AAX plugin formats for digital audio workstations on PC and Mac.

BPB Dirty Filter is our little gift to Bedroom Producers Blog readers and the music production community as a whole. I launched BPB a little over ten years ago and I enjoyed sharing the news about freeware VST plugins and music production software ever since. This time, BPB’s own VST plugin is in our news section and I couldn’t be happier.

Of course, none of this would be possible without our readers. Thank you all for your support and for reading Bedroom Producers Blog. And if you’re new here, welcome and subscribe to our newsletter to stay up to date with the latest news!

So, you can download BPB Dirty Filter for free from our website and use it as a distortion effect in your favorite DAW. Check out the demo video below for a quick look at the plugin and its features.

What Is BPB Dirty Filter?

BPB Dirty Filter is a dual filter effect with tube distortion. It features a high-pass and low-pass filter, a Slope control (12, 24, 36, 0r 48 dB/octave), a Mix knob, and Volume control. However, the most important parameter is the Drive knob which controls the resonance for both filters and the amount of tube distortion that is applied to the signal.

By boosting the Drive knob, the user adds resonance and distortion at the same time. As a result, BPB Dirty Filter sounds somewhat similar to a multi-band distortion effect. This is because the cutoff frequency will be distorted the most and the user can focus the distortion around a specific area of the signal.

How To Use BPB Dirty Filter?

There are many ways to use BPB Dirty Filter as a standard filter and a distortion effect.

With the Drive set to zero and the Slope set to 12 dB/octave, you can use BPB Dirty Filter as a gentle transparent filter for removing low-frequency hum or high-frequency noise.

Set the Drive to 35 and the low-pass Cutoff frequency to around 45 Hz to add thump to a kick drum. The same can be done to snare or any other percussive instrument. Experiment with different Mix values to find the perfect amount of distortion for your drum loop.

Of course, you can always go bonkers with BPB Dirty Filter. Set the Drive to 100 and increase the slope to enjoy complete audio annihilation. Again, the Mix knob is your friend if you want to get some of that crazy distortion without completely destroying the incoming audio.

Download BPB Dirty Filter

You can download BPB Dirty Filter for free exclusively from Bedroom Producers Blog. The software is completely free to use in your DAW for any commercial or non-commercial purpose. We are providing the plugin as-is without any express or implied warranty.

BPB Dirty Filter is available in VST, VST3, AU, and AAX plugin formats for digital audio workstations on PC and Mac. Both 32-bit and 64-bit plugin hosts are supported. Visit the product page below to download your free copy of the plugin.

UPDATE: Some browsers and AV software detected the EXE installer for BPB Dirty Filter as a threat. Don’t worry – the plugin is 100% clean and this often happens with new EXE installers. We submitted a false positive complaint and this should be fixed soon. In the meanwhile, you can now download the manual installation files, too (no EXE installer).

  That is often the case with new installers (false positives in AV software). The plugin is safe to use.

  It’s definitely a false positive, but I’m checking if the installer could be fixed to prevent this from happening. Anyway, VirusTotal shows it as 100% clean: https://www.virustotal.com/gui/file/abb8a63d8191314e465c9a210cfb87937f33d34cbcf169057999e03b19c5306c/detection

  Yes, it’s a false positive because it’s a new installer. I reported this to Microsoft. Still figuring out how to fix the issue with Chrome. On the other hand, Firefox downloads the file without any issues. And of course, VirusTotal says it’s clean: https://www.virustotal.com/gui/file/abb8a63d8191314e465c9a210cfb87937f33d34cbcf169057999e03b19c5306c/detection

    I downloaded on a mac
    then emailed the self install 64 vst2 to a windows PC, downloaded it.
    Chrome warned me about the file type, which I ignored
    
    Once downloaded I scanned it with windows defender and it was clean.

      Thanks for your comment! Yeah, it’s definitely clean, but some scanners on Windows obviously don’t like the EXE installer. Still, I added a manual installation ZIP just in case. And I reported the false positive to Microsoft.

  Had more time to test it, it’s one of the sweetest sounding virus out there. Clean but not boring flat GUI. Well laid out too, a joy to use. No zipper noise when automation is used. Kudos on the inclusion of 36 and 48db filters, often overlooked values.
  Ideas for a possible v2: Pan control of the wet signal, ability to only affect the mid or sides and an automatic hydro-alcoholic gel dispenser.
  Wait… Plugin, I meant plugin.

Hi Tomislav.
Awesome initiative, and as always great website which I visit on a daily basis. I look forward to try out the plugin, but it’s already obvious what great potential BPB has a brand, and I look forward to see what the surprises that awaits in future. Godspeed in both the mainstream and the underground scene, and have a great day!
Best regards

Hi Tomislav & BPB team.
Wishing you a very happy 10 year anniversary & well done 🎂😊👍 Respect BPB
Best wishes for the future too.

This BPB Dirty Filter sounds very nice in your video while played on my sound system, especially the distortion you added onto that drum loop, it has an awesome sound when added in the bass drum.

I look forward to trying it out with two Dirty Filter plug-in’s in one channel strip (one for the bass to distort the bass drum & one for the treble, adjusted separately)
It would be awesome to be able to automate this plug-in as well & even have a split channel audio file for left & right with it added for the treble, endless possibility’s 👍

Thanks so much Tomislav, for all of your kind offers, i very much appreciated them all, even if i don’t need them all, but as well for your hard work, time & your great write ups about the products that you share with us all.

Kind regards all

  Hi! Eager to try this out. Maybe late to the party with this comment/query.
  
  Why not simply offer the plug in as a dll instead of exe?
  
  I have never understood why developers do that, unless they wanted to include unrelated software.
  
  Obviously, that’s probably not the case here. Maybe there are dependencies that are included within the exe?
  
  In any event, thanks for your contributions to the plug in community!

Thanks so much for this! Honestly, I wasn’t expecting much from a FREE plugin, but this thing is solid and It sounds fantastic! The distortion is now in my go-to list along with Kush, Nembrini and SoundToys. The filters put this over the top.

I already used it to finish up a mix!

Thanks BPB! Is this essentially the same thing as the free BPB FilterCrusher plugin from a few years back? I remember loving that thing but it had some stability issues that sometimes messed up sessions. Looking forward to using this guy though.
