2019-08-02 Thread Marc Lavallée

Hi Richard,

My question was not directly related to the orientation API, but to the
method used to transmit its data to your server. You mentioned https;
either https AJAX or secure WebSockets (WSS) can be initiated by a https
request. Maybe a realtime connection using WebSockets is not required,
slow AJAX requests being fast enough. I was just curious.

Re: [Sursound] Ambisonic Hand Controller

2019-08-02 Thread Axel Ahrens

Hi Justin,

We just had a small project steering a sound source location with hand 
pointing. 
We used a commercial VR headset/controller to track the pointing direction. The 
direction is send to MATLAB via OSC from Unity. In MATLAB we calculate the 
loudspeaker signals using either Ambisonics, VBAP or a nearest loudspeaker 
mapping. The sound is played back via a 64 channel spherical loudspeaker array.

It is quite difficult to calculate the actual delay but it seemed quite 
'real-time'.

Don't hesitate to get in touch if you have any specific questions.

Best,
Axel
