[PD] Massive Multichannel System

[Fabio Kaiser]

Hi, 

I want to build an computer audio mixing/processing system based on PD. My 
questions are mainly concerned with the stability and reliability of the 
system. 
So what do I need to do to make a software design in PD stable? The software 
should be able to do some calculations, equalization and routing for 64x64 
hardware audio In/Out. 

What do you recommend?
- System? I thought Linux Debian. 
- Soundcard. RME MADI and the corresponding Linix driver seems to be a good 
choice.
- Configuration of PD? Are there some tricks to make PD rock-steady?
- Software design? What should I keep in mind when programming? 
- Long-term stability? This system should work on demand and for a long time. 
Maybe shutting down the system should not be possible for the user!?
- Does PD actually do multicore processing? 

Thanks for any help!

best

Fabio

[PD] Ambi_en-decode

[Fabio Kaiser]

Hello,
I'm trying to get a 2D, 2nd order ambisonics system to run using 
ambi_encode and ambi_decode.

The results I become seem to be faulty.

Am I right when I put the encoder result in a matrix (vector), multiply 
it with the decoder matrix?

Like, p=C*B
where p is the weighting of each loudspeaker for a particular position, 
C the decoder matrix

and B the Spherical Harmonics matrix (vector).
And then multiply the signal with each value of p to get the loudspeaker 
output!?


Results seem to be right for positions, which are the same as the 
loudspeaker positons.

But for positions in between I get something not comprehensible.

Maybe you can help me!
my patch is attached.

regards

Fabio

[PD] External compiling!

[Fabio Kaiser]

Hey, I've got an external written in C++ and don't know how to compile 
it, so I can use it in PD!

I already downloaded the MinGW compiler but don't know how to use it!

Can anybody help me??
