[PD] polynomial pairs in lpc filter

[Ed Kelly]

Ah! Now you've piqued my interest. I wonder if it would also run on a Bela board (Beaglebone Black hat - I have one of these).

It's really good that there's some low-latency platforms in small form factors coming out now.

Having gone through the grinder with this MSP->Pd port, when I get it working I'll be happy to try and phizz it into Bela. I started writing Pd externals precisely to enable speech manipulation, but I got stuck and moved on to other things. You've re-lit this fire!

 hi, well it is not a dissertation at all.i am working on some axoloti (a stm32 with dedicated midi and audioports, lowlatency audio board) modules for lpc playback. check out the axoloti, it’s nice!it is pretty hardware specific but sure i can share a github link, once it is up there. it progresses slowly right now, since i have a life as well (music…)

Oh gosh! Well spotted!

It loads, but I suspect I will have to interrogate the algorithms to make sure they are the correct interpretation of the vDSP algorithms in the original Max objects. This was the main part, and I've been a bit rusty at this - it's got me almost up-to-scratch again. A few more modules to port and it might just work!

Thanks Christof, and all of you...but

Simon Iten - when you've finished your dissertation could you share your results?

Still on it...
Ed

 you forgot to return your object (x) in mbc_lpc_tilde_new :-)

Jose...
I've stuck my head in the lion's mouth so I may as well go in for one more bite, although I promise you that IOhannes Zmoelnig is a REALLY NICE GUY.

 
I agree that edkellytista9 is a pretty stupid github name. It was done in a hurry for working on another project, but I'm setting up a more serious one because...you know...presentation is important.
 
I'm using Makefile.pdlibbuilder now - very cool. And deken ekext-0.2 coming soon.
 
I have a house. It's a bit of a dump but has a studio. I don't live there yet. We need to get the builders in!

 

...and my mbc_lpc~ port compiles but spits out an error:
mbc_lpc~: initializing
mbc_lpc~: free memory...
mbc_lpc~: allocated memory
Generating Hamming window for LPC analysis
 mbc_lpc~
... didn't return a patchable object
 mbc_lpc~
... couldn't create
 
I still don't know why. Perhaps Iohannes can help?
Ed

Got late into this discussion, but I'm really interested in this project and would like to help (even if I don't have much experience coding new objects and have been a little busy with my classes at the University).
 
Ed, any further success last weeks? well... also with the house... ;)

ouch.
thanks for pointing that out!
