Hi, I'm also trying to produce binaural output in pd.
vbap does not suit my needs: it's only doing amplitude panning, and with headphones, it can not produce elevation effects...

Right now, I've found bin_ambi that does lot of things (binaural, room effect, distance attenuation) http://iem.at/Members/noisternig/bin_ambi, but I'm looking for something simpler if possible...

I've heard about the earplug external that has been done by Pei Xiang few years ago, but I didn't managed to find it.

Does anyone knows how to get that external, or other binaural rendering external?

Thanks!
