These objects that I cant create come from patches within the WindowsXP distribution that I found here:
http://iem.at/Members/noisternig/bin_ambi
It's the only example documentation that I can find for how to use the complex iem_bin_ambi and iem_ambi objects. The individual object help patches dont give enough info to be able to use them (at least for my brain).
afair, Georg Holzmann has done a workshop on 3d-audio at the LAC2007 in Berlin; i'm sure he used bin_ambi and might have written up some documentation (probably the workshop material can be found somewhere online)
I've found the conference proceedings ...but there's not really any content for Georg's workshop.
[spec2*~] [spec2+~] [spec2-~]
these are part of the iem_spec2 library for efficient operations in rFFT domain.
I've got iem_spec2 loaded up ... but the objects still cant be created. Is there perhaps a dependency ...or maybe the OSX version does not supply these?
try creating [spec2_mul~], [spec2_add~] and [spec2_sub~] either as replacements for the objects above or _before_ loading the patch.
that works. Thankyou.
