I wonder whether it's impossible or whether there are ways to achieve
some kind of elevation effect with plain old stereo.

has a reference to blauert's work, but it's pretty sparse otherwise.
german wikipedia is more detailed:

and yes, you should have a good chance of faking some of those cues.
haven't tried it myself, though.

Thanks Jörn.
I wouldn't have expected to find anything on that in wikipedia..
I'll certainly experiment with it, maybe I can achieve what I envision.
Ambisonics would probably be far superior for that, but besides me
pretty much everyone else lacks an ambisonics system.
Thanks,
Philipp

given that fons has made ambdec available for everyone, anybody who wanted
to have an ambisonics system could have. i suspect you know this, but just
wanted to make sure it was clear.

the moderately hard part is to get enough speakers for usable height
reproduction.
the really awesome part is to get all your fans to buy such a rig, too.
at this point, some eq trickery does look very tempting...

Hello Philipp!
You can use csound - or possibly CLM or puredata or SuperCollider3 - to
achieve tis. In csound I you can do it with the HRTF opcodes. They are
designed for use with headphones.
In csound you can also convert b-format signals to stereo, again best suited
for headphones. I've done it a few times and the results weren't too bad. I
used the b-format to stereo conversion, by some kind of standard formula and I
converted some spekaer settings using HRTF, which gave very nice results.
In the csound manual, which can be found online at csounds.com, search fr
the spat3d opcode and see it's examples. There they convert the b-format 3d
signal to stereo using the formula. The HRTF conversion is done using simple
angle calculations and adding up signals. I can look it up and tell you, if
you'd like to know.
Kindly yours
Julien
