Subject: [Csnd] commentaries about vbap opcodes

So, I got vbap working in PureData and I found it very useful. I'm able to control the position realtime which is what I was looking for. I emailed the author, Ville Pulkki, and asked him about the possibility of having a k-rate controllable version for Csound. He replied and confessed that he has been away of Csound for very long time and he doesn't plan to get into it again any time soon. He said he remembered John ffitch doing some additions to these opcodes some time ago, so he might know how they are built.

Anyways, I'm just throwing this out there to see if I'm luck and we get a realtime controllable vbap, I prefer working with Csound than with the box-and-wire interface of pd!

Cheers,

Hector

Hi Art,

vector based amplitude panning: takes mono audio signal to some or other
fixed configuration of loudspeakers given position variables.

pan: essentially a particular case of VBAP.

Ambisonics: takes mono signal to ambisonically encoded signal that is
"later" decoded for flexible configuration of loudspeakers (OR an
ambisonically _recorded_ signal can be decoded to flexible configuration
of loudspeakers).

I think it comes down to whether you want a flexible number of
loudspeakers or not (or alternately but much less often exploited:
whether you want a flexible number of inputs or not).

Yours truly,
David
