Hi,
I am bit of a newbie and I'm intending to development an immersive audio-visual environment based on a mysql / xml database of sound artists. I would like to explore PD as the means of presenting data in a spatialised installation context, and ambisonics would add a lot to the experience.
The options available in PD are, as I understand
IEM bin_ambi http://iem.at/Members/noisternig/bin_ambi CUBEmixer http://puredata.info/Members/ritsch/News/cubemixer Ambilib http://music.york.ac.uk/mrc/download.php ambipan~, ambicube~ and vbapan~ http://cicm.mshparisnord.org/dl/ambipan.htm
Does anyone have any recommedations for this? My app is, at present based in X3D, and the position of sound sources are expressed as, for example
position='-3.20022 -.78022 17.05038',
how complex would it be to send this spatialisation data to PD, and use to PD as the audio engine for app for further real-time manipulation?
the CUBEmixer (and ambisonics in general) eats spherical coordinates (in degree); i guess your coordinates are cartesian, so you have to convert them. zexy's [cart2sph] does this for you (but outputs angles in radians, so you have to convert them to degree (e.g. [rad2deg])
