Raising Jake Studios has released SideMinder, a Dynamic Stereo Width Maximizer plug-in for macOS and Windows.
SideMinder is a tool that can increase (or decrease) the stereo width of a track, bus and/or master mix while automatically preventing over-widening and negative correlation that causes signal loss when mixed or played in mono.
SideMinder includes a stereo Width Enhancer section that ranges from mono up to 200% width enhancement with a Bass Mono control that reduces the stereo width below the selected cutoff frequency (especially important when mastering for vinyl).
The most important and unique feature of SideMinder is its stereo Width Limiter. This limiter uses latency-compensated look ahead correlation detectors that "listen to" the stereo signal and precisely and rapidly turn down the stereo width when the signal approaches negative correlation. Additional stages of filtering control the recovery speed of the width limiting action which is adjustable via the Release control. An output correlation meter displays the output signal correlation allowing before/after effects of the limiter to be observed (this meter remains active when the plugin is bypassed for overall comparisons).
SideMinder can be used as an audio processing tool to automatically increase and control stereo width or it can be used as a visualization/metering tool to help make better mix decisions.
