bx_cleansweep is a new Hi-Pass and Lo-Pass filter plug-in, introducing the new "Anti Crush Technology" (originally developed by Brainworx).

Analog style filter curves without the typical Nyquist problems, in a new great sounding filter design (taken from our pro mastering EQ bx_digital V2). First order filters (6 dB per octave) guarantee an extremely musically sounding filter set, and unique joystick control (taken from bx_hybrid) gives you fast and intuitive control.


bx_cleansweep is the plugin that should go into every mix channel as the first plugin. This way you can filter out any unwanted hi-end and lo-end, and the result is a clean and tight mix.

Ever thought about why there are Hi-Pass and Lo-Pass filter in every channel of the most expensive analog consoles (SSL, NEVE, etc.), but why most EQs are missing this feature?

Clever shortcuts (Alt/Shift/Ctrl) allow for detailed control over the X-axis and Y-axis of the joystick, and the EQ knobs can be set to precision mode by shift-click as well.


  • BRAINWORX' critically acclaimed filter.
  • Fully automatable.
  • Dedicated BYPASS switch in the plug-in GUI.
  • "Mouse Over" feature: adjust the parameters by holding the mouse over any knob and simply turn your mouse wheel.
  • Direct access: just type in any valid number into the text fields for direct access to the exact value.

Reviewed By RobertSchulz

The plugin in one sentence: 1x Lowpass-filter (Range: 20-22.000 Hz, 6 dB/Octave) and 1x Highpass-filter (Range: 20-11.000 Hz, 6 dB/Octave) which use brainworx' own "Anti-Cramp technology" and whose cut off frequencies can be controlled simultaneously by using the dedicated joystick.

I personally think the joystick component is a rather unuseful feature made much too prominent. Controlling both cutoffs for high-pass and low-pass filter can give you a solid band-pass filter, but the issue that the high-pass only ranges to 11k (although this is quite a great value for a high-pass on its own) limits the fun you can have with it.

The 6db/Octave butterworth filter indeed sound musical but one the other hand they are also very limited in the things you can do with them and allowing no surgical filtering. Not to mind about not having Resonance (Q) or gain parameters to shape the sound more to one's own needs.

I also do not like that each of the both filter actually has two separate control parameter, which again are very laid out far from each other on the desktop. You can use the little dials to the upper left side to swipe through the frequency spectrum and you also can do this via "mouse-over" controlling but these 2 dials neither give you information about the current cutoff frequency nor do they have the capability to type in the frequency.

This is what you do with the separate controls at the lower right, underneath the display. A kind of strange layout.

At last, I think that the name is misplaced. This plugin does not offer the accuracy to really provide clean and costumized sweeps as rather a raw but indeed very musical tool to create sweeps especially for the low-filter, since high-pass just cover half of the range.

The plugin could also have been updated to provide resizing, since it is small on modern desktops and values are hard to read.

Resume: For using it as simple low-and highpass-filter tool, it can be great, but even for that purpose it can give you a struggle because of its limited capacity and the way to use it.
