A1AUDIO has released A1StereoControl, a free for download stereo enhancer plugin in VST/AU plugin format for Windows and Mac. A1StereoControl plugin will help you to expand or limit the STEREO WIDENESS of your tracks using only one single knob. This powerful technique can be used on single tracks or groups tracks while mixing or even on a master bus in final mastering situations.
Stereo expansion can have unwanted side-effects, as many experienced mixing and mastering engineers worldwide are complaining. For example, bass frequencies should normally be simple mono. A1StereoControl has a solution for this problem.
“Safe Bass” integrated algorithm centers all bass frequencies below an adjustable value right back into the middle of the stereo field. This gives your tracks the solidity and definition you want while preserving maximum transparency and sharpness.
Also, you can use A1StereoControl to place your stereo signal inside the stereo field in a very intuitive way.
This plugin is available for free download on A1AUDIO website and I mentioned above, A1StereoControl is available in 32-bit and 64-bit VST/AU plugin format for both Windows and Mac.
2021 Update: This plugin is now available anymore!
