I started a similar project, for the web: http://ambisonic.xyz/ A new version (working, but not yet published) will be "full sphere". > So far we have come up with the following: > > you can seem to play ambisonics files with these: > https://github.com/ComposersDesktop/CDP7/tree/b085aa141fa93c98ae137feae5e7c58d656ddfdd/dev/externals/mctools > and > http://www.mega-nerd.com/libsndfile/ > > Are these the same? Short answer: no. > which one would be best for this project? I created a batch processor to convert and compress ambisonic files, using a combination of command-line utilities from the mctools and libsndfile, and others.

I use the h1b_rotate.dsp Faust processor from ADT (by Aaron Heller): https://bitbucket.org/ambidecodertoolbox/adt/ It provides a rotation transformation for each axis (yaw, pitch, roll). > Where can I find the best HRTFs? Try the ones from the ATK "kernels". > Which one is a good starting point for the “average” head? From the ATK kernels, there's the HRIRs based on the "spherical" model by Richard O. Duda (number 4 is the average, other variations correspond to smaller and bigger spheres). Try my player on ambisonic.xyz... There's also the hb1_to_binaural.dsp Faust processor from ADT, also based on the spherical model. The spherical model is is for "horizontal only" decoding, but for interactive media it's not a serious problem. > If anyone has some suggestions or tips for this project it is very > much appreciated.
