Re: [Sursound] Listening to FOA B-Format with head tracking
BTW, is anyone looking at getting this working with MIDI/OSC or suchlike? Reaper supports MIDI and OSC, and Reaper supports the TOA plugins, including the TOA Rotation plugin from the free TOA Core library...

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 [...] ___ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound

Best wishes, --Richard Thread is named FOA B-Format with head tracking. You offer an extension idea (which is good), but where can you find any TOA content? Best, Stefan P.S.: The (currently) two developpers thought of a real world CE application, this is not (just?) a research project. Nevertheless, the CE project could be extended to serve the scientific/academic community... :-) Hopefully the Mpeg has already included HT into its 23008-3 3D Audio framework, but hey, you should know more about this than me... ___ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound
Re: [Sursound] AmbiExplorer
Hi Michael, I'm sorry that AmbiExplorer didn't work on your daughter's device. If anyone experiences problems with the app please feel free to email me directly. I'm more than happy to try to figure out what's going wrong. A downside of Android development is the overwhelming variety of devices and making apps work on all of them. On a recent update I added the option of sending bug reports via email for non-crashing issues like no sound being heard. The best way of doing it is to close the app by pressing the back button or closing it in the app switcher. Reopen the app, load a sound file and hit play. If the time counter doesn't move, press the settings button on the top-right corner and select bug report at the bottom; follow the instructions for sending a log report via email. If after hitting play the app becomes unresponsive then wait for the system warning and send a report.

Re: [Sursound] AmbiExplorer
Hi Jörn, Did the reset button return the head or mics to face forward with the sensors off? The reset button, for now, should only works for when the sensors are off and the head/mics are being moved manually. Which means that yes, for now we will face north :-) In an upcoming update I'll make the reset button work with the sensors to reset the soundfield front to be in the same direction as the device when pressed.

I'm more than happy to try to figure out what's going wrong. A downside of Android development is the overwhelming variety of devices and making apps work on all of them. Yes, my thoughts, so not surprised that there could be a problem. Also why I tried 'the list': -thought if it was one of those silly 'works on = v.392 and = v.394, but not on v.393' 'things' then a wider audiece might nail it. -also I'm not a smartphone user, so thought it might be all my fault, anyway! I await my next visit to my daughter ... Thanks for the tips. Regards, Michael ___ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound
