Every major mixing console from brands like SSL, Neve, etc. has dedicated HP & LP Filters per channel. There is a reason for that.
Brainworx founder and CEO, Dirk Ulrich, has always emphasized the importance of accurate High Pass & Low Pass Filtering when treating frequencies in a mix.
During his long-lived days as a producer and engineer, working with acts and members of acts like Dream Theater, Toto and Michael Jackson, he found that some of the most critical parts of a mix lay within the sub-sonics and super-sonics of a sound. He figured, that by simply filtering out the spectrum above and below the desired core character of a sound, one could be well on their way to an immaculate sounding mix - even before the addition of any further dynamics or EQ treatment.
It was on this principle that Dirk designed the bx_cleansweep V2, a simple yet powerful hybrid High-Pass and Low-Pass Butterworth filter that implements gentle curves (6 dB per octave) in order to achieve a musical and non-intrusive effect when zeroing-in on a sound’s intended character.
A joystick control, much like an X/Y pad, helped facilitate intuitive and direct movements towards a cleaner sound stage. The bx_cleansweep design, like it’s bigger siblings – bx_digital V3 and bx_hybrid V2, features Anti-Crush technology. This analog model for filter curves prevents the harshness and aliasing found in many other EQs.
Now, bx_cleansweep PRO is the third reincarnation of the beloved filter plugin!
Sporting the addition of five filter types with adjustable slopes and characters for each, and spectrum analysis with an advanced frequency/phase plot, this next generation in the bx_cleansweep legacy provides an accurate and intuitive tool for your mixing needs.
Use it to tweak and tune the deeper regions of your mix, or create interesting spectral sweeps and effects when designing sounds. Make it the first piece in your chain on every single track, and you’ll be amazed at how just a little filtering can go such a long way.
