Overview

reating a Virtual S Channel!

The bx_stereomaker is a frequency-optimized M/S upmixing plugin that converts ANY mono signal to stereo, while keeping them 100% mono-compatible!

How many times have you had to deal with a signal that just won't fit in the mix because it's mono? But with modern mixes becoming both tighter and wider, adding reverb or modulation effects can easily destroy the tight center of a mono lead vocal, guitar, or synth track. Still, you need to process and spread those sounds to lay them perfectly into the mix.

bx_stereomaker can help.

bx_stereomaker creates a virtual S signal with analog style filters using Brainworx legendary M/S stereo algorithms. This plugin will take any mono signal and make it stereo while allowing you to balance the center position. You can even focus the process on specific frequency ranges in your signal. And you can solo the virtual S signal!

Features

  • Adjust the stereo-width added to the mono source signal from 0% to 300%
  • Hi-Damp knob allows you to create a warm sounding stereo expansion without sounding tinny
  • The plugin creates a virtual S channel (which you can solo)
  • The results are spectacular, and your signal stays 100% mono-compatible!
