Overview

This free plugin will be added to your account automatically when you join Plugin Alliance. If you already have an account you can download and start using this plugin today.

Polishing your mix’s low end can be tricky. Bass DI tracks can sound mushy, and kick tracks can lose their “pop.” Sometimes everything below 100Hz can become such an undifferentiated soup of noise that you just don’t know where to start! Start here: The bx_subfilter is just the ticket for adding clarity and definition to tracks that have troublesome low frequencies. There are lots of expensive and complicated EQ plugins out there, but when it comes to shaping your low end, the bx_subfilter is unique for its ease and simplicity. With just a few quick adjustments to its four-knob interface, you can breathe new life into those 808s that have been muddying your mix.

The bx_subfilter is a free plugin that borrows from the “Filter” section of its larger counterpart, the bx_subsynth. It’s the perfect plugin for anyone who loves the bx_subsynth’s unique approach to low-end filtering, but doesn’t need the subharmonic synthesis. If you think that cleaning up your low end shouldn’t break the bank or require twenty knobs, we’ve got a plugin for you.

Sign up at Plugin Alliance today and you’ll get instant access to the bx_subfilter, along with our five other free plugins. No dongles, no hassles, and no payment required!

Features

  • Tight Punch knob implements a resonant high pass filter that’s especially formulated for cutting problem frequencies in bass-heavy tracks
  • Resonance selector applies three peak settings to the filter – Low, High and Extreme – for accentuating punch while taming low-end rumble
  • Low End control applies a post-Tight Punch fixed bandpass filter, to achieve that perfect frequency balance
  • Input/output gain controls for level matching and preventing clipping

    The bx_subfilter is a nice and handy tool to beef up your low end -- super simple but effective. I just used it to give a bit more oomph to one of my ongoing projects. No brainer!

    Taken from the awesome bx_subsynth this cheeky little bottom end exciter really enhances the subs in what ever you stick it on! You'll have your neighbours complaining in no time.

    This feels like a van load of extra sound just turned up at your mix and added an extra octave. Brainworx -- worrying bassbins since 2017.
