IEM's bin_ambi is a sophisticated binaural rendering system via higher
order Ambisonic spatialisation to virtual speaker arrays.

FIR~ is very CPU intensive for HRTF processing. It's much better to
use frequency domain convolution with fft~ & ifft~ which is the case
with bin_ambi.
I've listed some publicly available HRTF sets on my blog here: http://blog.soundsorange.net/2005/11/09/hrtf/

Hi all,
I'm considering whether to use the earplug~ HRTF external or some alternative implementation of binaural spatialization.
On the plus side, earplug~ seems quite easy to use.
On the down side, earplug~ seems not to handle any sample-rate stuff
at all, so I'm wondering which samplerate the impulse responses in the earplug_data.txt are sampled at (because obviously it would be
somewhat weird to use them at another rate...).I don't really need the interpolation provided by earplug~ either,
so I guess I could save some CPU by using FIR~ directly, but then I need to obtain some HRIR's (ideally both at 44100Hz and 48000Hz sample rates).So: has someone already made a binaural processing patch using FIR~
and some set of impulse responses and would care to share it?Some context for the curious: I'm trying to auralize 4D space using
4D room simulation, with an "ear" made up of several co-solid listening points in the 4D space, each mapped to a 3D source point for binaural processing.Thanks for any tips,
Claude
