A1StereoControl

Used this for years. Writing this in in 2024. and prefer it even over some paid options. Clear visual layout that's easy to understand. Nothing fancy but as must have as a screwdriver for cleaning up mixes. The ability to expand stereo width while keeping your lower frequencies from widening is so easy.

Sometimes a widening function on a mastering compressor or equalizer is good enough. This is for when they aren't. It virtually never fails, is quite easy to use and gives some very useful extras like Mono-folding bass frequencies, phase controls, as well as input and output gain control. Compared to other stereo wideners, it's just better.

There are a kajillion stereo utility plugs in a similar vein, so which do you use? This one. It's efficient, stable, seemless, and versatile.

This is a great sounding, easy to use stereo widening device. Simple clear interface and provides the ability to both widen and collapse a stereo signal, then pan it within the stereo field. Add reverb to a sound, thin the stereo width then pan it to you'd desired location. Puts things in a specific spot and increasing/decreasing the reverb moves them closer or farther back. A great device, highly recommended.
