Dear Surround Sound Discussion Group, I have been following the emails here for a few months now. Thank you all very much for sharing and discussion.
My name is Henk van Engelen and I work for the music and audio production company spook.fm in Amsterdam. We have been working on sound design and audio production for 360 film (cinematic VR). Along the way we have developed some tools and a workflow to watch and rotate a 360 video on your desktop (in Kolor Eyes) and sync play state & pitch/yaw of the corresponding ambisonics sound field in Reaper (with ATK rotate plugin). We will share some tools and templates for this in the next week or two: we are working on some tutorial vids. The idea is that we can deliver our clients a b-format mix (for spatial/positional audio) together with a stereo mix (for music, non spatial audio). We are involved in a project to make a VR video player. In this player we very much want to add direct support for ambisonics audio with binaural decoding (and maybe stereo decoding for desktop use), and a synced stereo track for the non positional audio (like music). With this project we hope to open up the possibilities of using ’native’ b-format for the VR market and all the great (vst) software for your DAW that is already available. My question is: Who can help us find the best libraries for ambisonics audio to use in the 360 Video player. 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? which one would be best for this project? Then we need to be able to rotate the sound field. I found the rotate class of this one: http://www.mshparisnord.fr/hoalibrary/telechargements/code-source/ but it seems to be only rotating around one axis (Yaw). I really would like to rotate around all three. I also found this one: https://github.com/greekgoddj/ambisonic-lib unfortunately this library does not seem to be very well kept and supports only mac Are there other options for rotation? People have experience with these libraries? Which one would be best for this project? Step three is the binaural (and maybe stereo) decoding. We are thinking of using the HOAlibrary for this. Where can I find the best HRTFs? Which one is a good starting point for the “average” head? If anyone has some suggestions or tips for this project it is very much appreciated. I will keep this group informed about future progress. thank you, Henk van Engelen Rapenburgerstraat 109 1011 VL Amsterdam T: +31615555694 M: h...@spook.fm Spook.fm | Facebook -------------- next part -------------- An HTML attachment was scrubbed...
