IEM's bin_ambi is a sophisticated binaural rendering system via higher order Ambisonic spatialisation to virtual speaker arrays. http://iem.at/Members/noisternig/bin_ambi
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/ Nick http://soundsorange.net On Sep 4, 2008, at 4:09 PM, Claude Heiland-Allen wrote: > 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 > -- > http://claudiusmaximus.goto10.org > > _______________________________________________ > Pd-list@iem.at mailing list > UNSUBSCRIBE and account-management -> > http://lists.puredata.info/listinfo/pd-list _______________________________________________ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
