Here I am again, pushing for someone to do something for us ambisonic users :-)
I have been inspired by Hectors ambiexplorer app that was not compatible with my old android phone. https://play.google.com/store/apps/details?id=net.hcenteno.ambiexplorer&hl=en The goal is to listen to a first order .amb file using head tracking. Can it be simply done with windows or linux ? I think the components are almost here, DIY Headtracker for a cost of around 30 us $ controlling the b-proc VST followed by a VST for FOA B-format to Binaural output could be one solution. DIY head tracker ww.rcgroups.com/forums/showthread.php?t=1677559 http://www.rcgroups.com/forums/showthread.php?t=1677559&page=6 - Quick start Code and GUI can be found at google code http://code.google.com/p/open-headtracker/ It took 4 weeks to get the hardware from china, and around 2 hours for me as a complete aurdino rookie to connect the sensor to the Aurdino nano and load the headtracker software. It streams outputs strings like this 33.12,53.24,56,34 with the 3 xyz sensor values over the usb port showing up as a serial port on windows. I remembered I had seen this: http://www.york.ac.uk/inst/mustech/3d_audio/vst/bproc_help.html B-Proc allows you to rotate, tilt and tumble a complete first order B-Format soundfield. The order that these operations occur in is important, since it affects the final orientation of the soundfield, as all operations are with respect to the central listening position B-Format to Binaural Any B-format to Binaural output or this faking it: http://vvaudio.com/downloads VVmicVST as output according to this description > For something easier which works well, try back to back cardioids > - pointing them slightly forward > - going slightly hyper. > > I like this very simple decode. > >Used to use this a lot on Soundfield recordings when you couldn't do nowt >but listen straight from the headphone output. Like Ricardo says, works >well - with head tracking I'm pretty certain it would be fantastic - > dw I think dw wrote the above OR http://www.tech.dmu.ac.uk/~dylan/z/dylan/teach/ Multitrack spatial production: Ambisonic / Multichannel / Binaural Or any other Ambisonic to Binaural VST. At the moment I belive the only missing glue is to be able to use the serial input stream to control B-Proc. If I am to do it I know it will take a long time :-) If the complete solution is running on windows, linux or android. I do not care, I know Hector is looking in to a solution for the current ambiexplorer android app so you don't need to tape the phone to your head. Any pointers to do this with other software than my take on this is welcome.
