Do you actually like dolby headphone?
1) I always thought dsp will hamper listening experience. I always listen with no equalizers, no dolby virtual solutions,no beats just hear the music/movies that meant to be heard by the record producers.
2) But seeing dolby ads of home theater v4 (and nokia lumia) seems compelling.
3)Do dolby heaphone/virtual speaker/prologic etc create good listening experience? (i know dolby digital is a codec and i wouldnt argue against it)?
4)Do dolby heaphone/virtual speaker/prologic etc change the pitch tone of the sound to make it unnatural in addition to 3d spatializers that create a somewhat natural listening pleasure? (contrasting argument)
5) AFAIK Dolby headphone works best with 5.1/7.1 channel insput and it works just as a spatializer for stereo input just like the stero widening am i right? or does it create surround from stereo?
I have heard that combining prologic with Dolby headphone create complete surround for stereo (Prologic converting stereo to 5.1 but doest it require the source to be prologic encoded ?
6) Also can we combine two DSPs togather like dolby prologic + dolby headphone . Will it create unnatural echo? How can it be done in my setup (i do not see i can use prologic + DH togather in my realtek drver setting)...
7) SO is dolby headphone good ? will it degrade my listening experience?
1) Whether DSPs help or hinder the listening experience is for YOU to decide. In the context of music, though, it will unquestionably distort the original signal; whether it's a pleasing distortion or not is something you have to decide for yourself. (Note that some people do like a bit of euphonic distortion in their music.)
3) That depends on what you mean by a "good listening experience". Are you fine with the usual headphone presentation, or do you think it should sound more like stereo speakers in front of you?
4) By their nature, headphone surround mixing technologies tend to make things sound a bit different as a nature of the spatial processing. Might come across as a bit less "clear", for lack of better words. Dolby Headphone in particular also seems to reduce the treble just a bit and dial up the bass a bit.
5) DH naturally works best with 5.1/7.1 sources since the general point is to deliver that listening experience over headphones. With only stereo sources, you only get the experience of two speakers in front of you. Some people may actually find that pleasing for music, but most of us around here use DH as a means of getting a situational awareness advantage in games, for which a stereo source signal would be useless.
Note that a Dolby Pro Logic-encoded signal is NOT strict stereo, and as such a proper decoder can retrieve the extra channels and use that for a Dolby Headphone mix. It's naturally not as good as a discrete channel mix like Dolby Digital due to crosstalk in the two channels, but it does work.
6) You can chain together all the DSPs you want, but the effects may not be desirable depending on what those DSPs are doing. In your example, you shouldn't need Dolby Pro Logic at all unless you're trying to get a surround source to an external Dolby Headphone DSP and can't use S/PDIF to do so.
7) I think it's good...for gaming, anyway. I don't use it or any other headphone surround tech for music.
