Buzz Cut

Buzz Cut is an audio clipping plugin designed for ease of use and great sound. The intuitive scrolling waveform display gives a clear visual depiction of the processing and makes the settings easy to dial in. The “HQ” mode offers a cleaner sound for when hard, digital clipping produces too many artifacts. While mixing, Buzz Cut works great for leveling off drums and percussion while retaining the impact of the transients. In a mastering context, clipping with Buzz Cut can allow the perceived volume of the audio to be increased without raising the peak levels.

A1StereoControl

With my A1StereoControl plugin you will be able to expand or limit the STEREO WIDTH 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.
As many experienced mixing & mastering engeneers worldwide are complaining, stereo-expansion can have unwanted side-effects. Especially the bass frequencies should normally be simple mono.
As you may guess, my plugin has also a solution for this problem. The integrated "Safe Bass" algorithm centers all bass frequencies below a adjustable value right back into the middle of the stereo field. This gives your tracks the solidity and definition you want while preserving maximum transpancy and sharpness. Similar techniques were used by professional studio producers over ages
with either expansive hardware devices like elliptical equalizers or even advanced m/s-processors. With my plugin you will be able to manage this complicated task with a minimum effort.
