Greetings AVSForum (first post!),
Having searched these forums, others and generally the www at large, I find myself without a firm understanding of Dolby Headphones' source, encoding and decoding requirements. Let me explain and maybe you can help clear up my confusion. For context - I'm trying to understand the use of dolby headphone tech on PC (game) audio source output on (of course) headphones.
What I think I know is that Dolby Headphone is an alteration of surround (5.1 channel) source material to create a 2.0 channel (aka stereo) output for use with headphones.
Unless pre-encoded in DH, the source requires encoding to DH. This is the function PC sound hardware (onboard or discrete, if so featured) performs.
Once encoded, the DH source is output from the PC sound hardware and will require decoding to be properly played.
Having written this out - I've confused myself even further, so any clarifying assistance is much appreciated!
