Hi, I'm trying to implement a binaural mixer versus an ambisonic-to-binaural decoder, for a comparison of their performance. For the binaural mixer I'm trying to use the CW_binaural~ object by David Doukhan (which I spotted on the list), since the earplug~ object uses MIT Kemar's hrtfs which don't perform well with elevation (for me) while IRCAM's HRTF database is based on real listener's with more realistic results.
I can't quite manage to get CW_binaural to work, I've got th VC++ installed and the object seems to load fine however it doesn't detect the HRTF_PATH environmental variable for the HRTF directory. Have other people experienced the same problem? Also I would like to ask (David?) if there is a chance of a linux version of the plugin?
Cheers, Archontis Politis
Have a look at the iem_bin_ambi library too, the "bin" standing for binaural here.

Hi Peter,
this library by IEM is following the other approach by converting an ambisonic decode to a binaural stream, which I have already implemented and want to compare against a "pure" binaural panner, like earplug~ or CW_binaural~.

Hi, do you got specific error messages telling that it did not detect the environment variable?? Concerning the linux version of the plugin, I made it run on ubuntu. If you're interested in that version, I can put the binaries on my website. I also REALY should release the clean source code very soon, and I've been quite busy those days. If you need it quick, I can provide you the source code as it. Otherwise, If you think you can wait until the end of the week, I can rush and provide a CLEAN package for the rest of the community. The code is operational since a long time... I really need to spend those last hours finalizing it.... Let me know about your needs and I'll try to fulfil them. See ya!

Hi Doukhan,
Sorry it seems like I was a bit hasty! After a Pd restart it picked up the environmental variable and I'm ready to play with it.. However a linux version would be sweet, no rush though - a clean package would be fine anytime..
On a different note (slightly off-topic), as I said initially I'm working with an ambisonic-to-binaural encoding approach, which basically adds a weighted static set of HRIRs (depending on the ambisonic decoder part) resulting in 4 impulse responses which are always the same for any kind of rotation, panning etc. Doing this with the Kemar set I get quit a good performance on the horizontal plane but quit confused elevation cues. Same thing with the LISTEN set gives better elevation (more individualised) but the result sounds quit filtered compared to the original sound. I was wondering if it has to do with the set itself or it's something relevant to the addition of HRIRs. Have you experienced anything similar?
Best regards, Archontis
