hi list,
this is more of a general DSP question...
i am working on an LPC playback and mangling system for axoloti. i have most of it working and i am now trying to shift formants in the filter to change voice character. i found functions to convert reflection coefficients into polynomial pairs and presumably i should be able to shift filter frequencies in this representation of the data. unfortunately i have no clue how to do that. any hints, papers, code snippets etc. are very welcome.
or if someone wants to take the time to explain, you are of course more then welcome
thanks for any suggestions
calculate the zeroes (roots) of the polynomial i guess.
still hints are very welcome :)

Hi Simon,
I remember trying to extract such information from pd-list members about 13 years ago...the silence was deafening!
I remember trying to get some help with why my ported lpc object wasn't initalizing properly earlier this week- also silence.
However, I soldier on regardless. If you have any ideas about why my mbc_lpc~ object doesn't load then please hack it and return(github details at the bottom) but also take a look at the original code for mbc.allpass~ - it contains various methods that are commented out for calculating filter coefficients, and there may be some clues in there for you to pick at.
I've never quite got to the bottom of calculating Line Spectrum Frequencies and manipulating these as formants, but it sounds like the project I was trying to pursue so many years ago (before my idiot managers pulled the funding and tried tobotch their own project together).
Anyway - here's how far I've got with the port - do you think you could share ideas and code with me? it may speed things up at my end...

that's probably because it was totally unclear (at least to me) what you were asking.
if your object cannot load
- replace "print" with "post"
- run Pd with "-verbose".
- check the console. check the terminal.
- check the file type.
- check whether all the runtime dependencies can be found.
etc.
gamdsr IOhannes
verbose...
tried...(all pd search paths)...and failed tried...(current directory)...and failed
I will probably work it out sooner or later. The only external functions I'm using are fabs() from <math.h> and fft_mayer/ifft_mayer from m_pd.h

does Pd find your external? if so, does it print an error message? (raise verbosity in the Pd-console to "DEBUG" as well).

for fabs() you must link against libm.
also, if the *only* external function you are using from m_pd.h is [i]fft_mayer(), then it is pretty clear that the external cannot load: you need at least class_new() and pd_new() as well...

hmm... each and every one?
just to make sure: with "external" you mean some dynamically loadable file that somehow adds new [object]s to Pd?
if we can agree on that, you might want to read my externals howto [1]. (for completeness sake, there are other ways to write externals; but so far the only thing i've understood so far is that "it doesn't work", making it impossible to tell which path you took before you lost your way).

Apologies - I'm trying to do this while buying a house...I don't know if that is simple in Austria but it isn't here.
But, I was indeed firing blind myself. I assume you are referring to line 665 to 668 in mbc_lpc~.c: mbc_lpc_class = class_new(gensym("mbc_lpc~"), (t_newmethod)lpc_new, 0, sizeof(t_lpc), CLASS_DEFAULT, A_DEFFLOAT, 0);
After reading your email I assumed it was something new, but of course I had just copied, pasted and altered code from a previous external (and forgot) Perhaps it's to do with linking to libm, so I'll check the makefile once I'm back in a reasonably stable (time-wise) environment.
BUT - I've never really understood (in ~13 years of external development) what all those args to class_new() did before, and you've forced me to look deeper into m_pd.h I should thank you for that - and yes, I learned how to write externals by reading your howto, in 2005 I believe.

you know, "edkellytista9/LPCToolkitPd" can be about everything; why would i have thought about a github project?
anyhow.
compiling your file prints a huge fat warning:
mbc_lpc~.c:661:1: warning: control reaches end of non-void function
[-Wreturn-type]
which is indeed true, and it is telling you that your constructor function lpc_new() is not returning anything (and definitely not an object).
the externals howto [1] says:
The constructor has to return a pointer to the instantiated data space.
but even with that fixed, it doesn't load. now i've asked you to:
- run Pd with "-verbose".
- check the console.
to which you replied:
tried...(all pd search paths)...and failed tried...(current directory)...and failed
however, when i try to load your external i get:
tried /tmp/zmoelnig/LPCToolkitPd/mbc_lpc~.l_ia64 and succeeded load_object: Symbol "mbc_lpc_tilde_setup" not found
which is writing out as plain as possible that your external misses the only function that it *must* have in order to be any use to Pd: the callback function that allows your external to bootstrap. (while blindly copying, you renamed your object but forgot to rename the setup function).
apart from that:
- please mark all your functions as static. you will get nameclashes
otherwise. making your objects use totally different functions than you expect (and possible making the object of other people use different functions).
- template Makefile 1.0.14? seriously? consider switching to
pdlibbuilder. it's much nicer. for starters, it doesn't make bogus file-extensions on linux/amd64.

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?

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.

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

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…)

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!
