Press Play Stereo Helper v1.2.0 x64 x86 VST VST3 AU WiN macOS [FREE]

Press Play Stereo Helper is a free stereo processing plugin for producers who want to adjust width, inspect mid/side balance, and check how their mixes translate to mono. It suits home studio musicians and mixing hobbyists working with stereo tracks that need more space or a clearer balance between the center and sides.

You can audition the mid or side signal separately and adjust the gain of each component. Width control helps shape the stereo spread, while a natural-sounding delay effect adds depth. An input indicator shows whether the incoming signal is mono, and mono compatibility checking helps you assess what happens when stereo playback is collapsed. Panning, phase inversion, and left/right channel swapping cover additional everyday routing and correction tasks.

On Windows, Stereo Helper is available as a 64-bit VST or VST3 plugin for Windows 7 and later, making it suitable for compatible versions of FL Studio and Ableton Live. The listed Mac formats are AU, VST, and VST3, with support starting at OS X 10.7; this version is not prepared for Catalina or newer.
