​Natural crossfeed Foobar2000 component designed to give a realistic crossfeed / speaker simulation effect on headphones or earphones while producing a wide soundstage and zero sound coloration.

Simulates speakers spaced 30+30 degrees apart (classic stereo setup with better front projection of imaging) or 50+50 degrees apart (widened stereo setup with more similarity to classic headphone soundstage width)

Update 2016-07-26: I’ve put the “secret” update in public as v2.1, containing a new set of impulses. They also come in 30+30 degree and 50+50 degree versions but are derived from actual measurements around my head.
