[PD] earplug~ or FIR~ for HRTF?

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
Thanks for any tips,
