Alright here is my last version of the patches. Even if no one
else is interested, I consider the problem solved at this point.
Whenever the calculations are reset, there is a brief transient.
digression:
That's because I can't find a way to precisely calculate a signal
which represents the s
This one works within block sizes of 64, by using an [block~ 128 2] .
Now, I've got one where you add an argument and use arbitrary block
sizes. It's much more useful, this way.
[sxcov~ 2048] works within a blocksize of 2048, and calculates the
symmetric cross covariance of two signals.

Here's an abstraction for computing a symmetric cross-covariance, this
way. It outputs the cross-covariance, xcov(k)=sum(i=-32,...,31;
s1(i+k)*s2(i))
It's still pretty ugly, and the details of the math confuse me a bit.
I'm still working on the one-sided cross covariance function for
delays, like
Hi Tania,
Download the distribution from Paulś website: http://aubio.piem.org/pub/
tar xvzf aubio-0.3.2.tar.gz
There is no makefile because
./configure
should create one, then you type
make && make install.
do a
ls /usr/local/lib/pd/extra/aubio.pd_darwin
if you´ve installed PD from source. If

these should be in the iem_tab external (included in latest pd extended)

Mathieu's right here... It can be done with abstractions. I'm not
sure that mine are all correct, but I've used this technique a couple
times without making complete abstractions for it...

No more news on where you might find the externs im afraid,
but in case you do get the iem table one working [tabsend~]
I suggested would be useless because two of them would
seem to be asynchronous and make nonsense of your
correlation (is that right?). Two triggered [tabwrites~]

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:

The problem is that two of the objects I have in the patch that Andy sent me
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 w

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.

Hey,
I am not quite sure what exactly what you are looking for, but there
are a couple libraries that are meant for getting data from sound,

it's data correlation (not audio)
