[PD] cross-correlation in pd ?

[Ed Kelly]

Hi Tania,

aubio is quite easy, provided you have libsamplerate, libsndfile and fftw3 installed.  It is pretty essential that you instal pkgconfig as well, since some libraries rely on that to send information as to where they all reside on the hard disk for compilation.
So, aubio in steps:

First, URLs:
pkgconfig: http://pkg-config.freedesktop.org/wiki/
libsndfile: www.mega-nerd.com/libsndfile/
libsamplerate: www.mega-nerd.com/SRC/
fftw: http://www.fftw.org/
and aubio-0.3.2.tar.gz
unpack them all in the same directory. Put the attached script in the directory all the other packages are in then...

Then you can use this script to compile them all (see attachment). You will need to be logged in as the administrator, and know the administrator password. You must open Applications -> Utilities -> Terminal

# then type
 
cd /path/to/where-you-unpacked-the-files/
sudo chmod 744 instaubio.sh
<password>
./instaubio.sh

have a look at the script using textedit - it uses fairly common unix stuff, and I'm sure you could work it out yourself, or you know it. Maybe I saved you some time! ;-D but aubio needs things in the right order.

PS I know Paul is writing up his thesis right now, so maybe he's a little quiet!
PPS do you know much about linear predictive coding and formant analysis?

Best,
Ed

1- tab_mul
2- tab_cross_corr

tare not created, I have the IEMLIB included in pd and the rest is ok.
Please tell me whether they are coming from same library or they are part of some other one which needs to be included with it 

Can you please check them on yours pd?

1- how can i find this IEMLIB_R1.15 library, as some of the objects in the patch you sent me can not be created.


2- I am using pd extended  0.40 on mac osx


In Pd-extended, that should all be in the "iemlib" library.



3- how can I include aubio in pd when I download it, a little guidance needed here  


That I don't know, I haven't played with it yet.

 thanks

I found a helpfile for "table cross corr" IEMLIB_R1.15
Don't actually have the external though myself for some 
reason.

Looking at the helpfile it would be suitable for audio
after using [tabsend~] to fill the tables.
