i need to get a windows box anyway, so i'll have a look at SSR
asap... sounds like it allows for easy A/B comparison between the

It currenly runs only under Linux.
/me punishes self with a very large hammer while trying to come up with
an excuse for not having tried it ages ago....
will rectify that asap. thanks for this pointer! i had always filed your
work as "windows-only, maybe later", don't know why.
ok, so i've gotten around to building the ssr, and tested the binaural
renderer. very nice, altough a bit tricky to use at first.
as expected, externalisation is not happening, but then i know i'm a
pathological case wrt binaural.
still, it's a very useful tool on the road, and i'm getting a vastly
better idea of what's going on in my mixes than with plain stereo or
uhj-over-headphones...
my test case (apart from single sources being panned around) is
2nd-order ambisonics over a virtual 5.0 itu layout rendered to headphones.
yeah, i know, that's totally sub-optimal for ambisonics, but it's what i
have to deal with atm, so i want to experiment with the artefacts.
naturally, a virtual hexagon would produce better results...
i'd like to recommend ssr to other sursounders on linux, provided you
are comfortable with compiling software. the source package is easy to
understand and comes with very extensive pdf documentation (not counting
a number of papers on ssr which are floating around on the web).
download the example scenes as well, they are helpful to get started,
particularly the example that explains how to hook up an external source
such as a DAW (oh yes, ssr works with jack).
apart from binaural, it does ambisonic, vbap and wfs rendering to
speakers (which i haven't tested yet). i expect the ambisonic rendering
to be not as polished as optimized dual-band decoders, since the matrix
seems to be generated on-the-fly (allowing you to play with arbitrary
speaker layouts iiuc), but it should be a valuable tool nonetheless.
i haven't quite understood the GUI yet, but i'm sure the fog will lift
eventually. the xml config files are straightforward.
best,
jörn
