Tasty Mousakas has released DH Wrapper VST, a freeware VST plug-in that processes 5.1 surround sound content and outputs 2 channel binaural signals.

The result is surround sound through headphones. “DH” stands for “Dolby Headphones” as this VST plug-in wraps the functionality of the “DOLBYHPH.DLL” file installed with software DVD players.

DH Wrapper VST is simular to Chungalin’s Dolby Headphone wrapper DSP plug-in for Foobar 2000.

Check Dolby Technologies for information about Dolby Headphones and how this acoustic illusion is created.
