Intentionally subtle headphone crossfeed filter

In plain words

This is a headphone crossfeed filter designed to subtly blend audio between left and right channels. It helps reduce the unnaturally wide stereo separation that can occur when listening to headphones, making the soundstage feel more natural and closer to speaker listening. The tool is hosted on GitHub and is aimed at audio enthusiasts and headphone users seeking to adjust their listening experience.
