I don't know enough about how the ear works to know how directionality works, but it does it somehow.
Also, the review says that the unit took a song that was multi-miked and mixed with absolutely no attempt at coherent soundstage, and when it was processed, the instruments were all laid out separated in a realistic spread. That one sounds like a reviewer who is treading into hyperbole. I don't see how it could take apart a mix and rearrange the position of the instruments. I've heard synthetic stereo systems that attempt that, but inevitably, the pluck of the bass gets separated from the fundamental, and the harmonics of an oboe gets spread all over the place.
If it's reworking the stereo spread itself, not just placing it within a virtual space, it can make stereo recordings out of mono ones. Does it know to put violins on the left?
It sounds like most people use it like the DSP settings on an AV amp for home theater. I can totally see that. I use a DSP setting for converting stereo to 5:1 on my Yamaha receiver, but that's a subtle thing, and it doesn't change the front soundstage imaging built into the recording. I don't know if I want a DSP to monkey around with that.
It's been my experience that I don't want multiple synthetic environments. I just want the one that works right in my particular room to fill it with a natural balance. I definitely want the layout of the channels that the engineer mixing the film creates in 5:1 movies. I wouldn't want to add reverberation simulating a big cavernous theater or anything like that. And in stereo and mono music, I want to maintain the forward spread the way it is in the recording.
I guess all this is answered in the Realiser threads, but let me chime in so there will be no confusion for anyone stumbling here.
Realiser does not do any "DSP magic". It does not take apart, rearrange or synthesize anything.
Everything will sound just like it would, with you sitting in that room with those speakers playing. There is no "virtual space", it's _that_ space that you recorded, including the ambiance and any acoustic properties.
If you want to upconvert stereo to 5.1 or something else "DSP magic" like, that has to be done by you in the source. Realiser does not mess with the sound (but it does have some EQ/LFE etc tuning capabilities).
There is no need to use the head tracker if you don't want to. You don't need to move your head around or stay still like a statue. No matter what, the imaging is uncanny, speaker locations are always there. Of course to best fool your brains, you should sit still and/or use the tracker, but regardless the result is remarkable. Anyways if you are listening some other room that you are not currently sitting in, it's hard to completely fool brains. I'm currently listening to a 7 x Genelec 8260A setup, but how am I supposed to "believe it" when I don't see the actual speakers? Sound is coming from my walls. Yet the speaker positions are dead accurate, imaging is spectacular and it's nothing like Dolby Headphone and other simulation crapola.
