		<description>You need special coefficients to make a 4th order SDM stable.   I have both C code (compiles under linux/cygwin/mingw) and some Matlab/octave code.

I&#039;ll give you my coeffs and diagram, but you need the Matlab SDM toolbox to genereate your own coeffs.</description>

		<description>I am looking for matlab code to perform delta-sigma decoding, i.e. going from a bit stream to the analog. Specifically, I would like code to do 4th order delta-sigma de-modulation.

Any suggestions?

		<description>You can email me at lm317t (_at_) gmail (_dot_) com if you don&#039;t mind.  Comments on the blog are a pain for casual conversations and much slower too!  There is also a mailing list for BRP-PACU, but email to the above address is fine.

When you installed the library, it puts it in /usr/local/lib, which is not in your LD_LIBRARY_PATH variable or is not included by /etc/ld.so.conf by default.  When compiling gtkdatabox you could also pass it the &quot;--prefix=/usr&quot; to fix this

The jack errors look like a buffer underrun, make sure other programs can use jack successfully for capture and playback.

Buffer underruns (XRUN) can usually be corrected by increasing buffer sizes and counts in qjackctl, but that usually won&#039;t cause a crash, at least not w/ alsa.  You may also want to see if you can use alsa or another sound driver rather than freebob.  See if you get the crash with alsa or oss with your PC sound card, just as a test.</description>

		<description>Ok
I found 2 &quot;-framework Carbon&quot; in this file and removed it.
running &quot;make distclean&quot; was not possible (even in root), but the rest worked.

Running brp_pacu in a shell :
~$ BRP_PACU
BRP_PACU: error while loading shared libraries: libgtkdatabox-0.9.0.so.1: cannot  open shared object file: No such file or directory

So I made:
 ln -s /usr/local/lib/libgtkdatabox-0.9.0.so.1.0.0 /usr/lib/libgtkdatabox-0.9.0.so.1

And now it works !!
Not perfectly because it crashs and make jack crashs too (sometimes after 2seconds, sometimes 1minute..), but I managed to test it (PinkNoise, delays, capture). Great job!

You can see the jack messages and bcp messages here:
http://seasan.free.fr/bcp/crashBCP.txt

If I can make it not to crash, I&#039;ll use it this week-end on a professionnal sound system and compare it with &quot;an other software&quot;.
Thanks for your help and for your time on this project.</description>

		<description>Hmm, looks like the version Andreas, the Mac developer, uploaded doesn&#039;t put the -framework Carbon in the Mac auto detect.  In other words it works only for the Mac.  

You can do the following in Linux without my next upload, otherwise you&#039;ll have to wait:

remove &quot;-framework Carbon&quot; from Makefile.am
run: 
make distclean
aclocal
autoconf
automake
./configure
make
sudo make install</description>

		<description>Hi,
Thanks for your answer.
I downloaded the file BRP_PACU-2.0.6.tar.gz (no alpha..) from this page :
http://sourceforge.net/project/showfiles.php?group_id=204657&amp;package_id=304598&amp;release_id=658804

It&#039;s not the Mac version, isn&#039;t it??

The command &quot;grep -iR Carbon *&quot;  in the source directory returns this :

		<description>Hi SebB
Please make sure you downloaded the latest file BRP_PACU-2.0.6alpha.tar.gz (from all)

This is the linux version, there is a Mac version that may not compile on *nix!

The command:
grep -iR Carbon * 

turns up nothing in the latest source directory 2.0.6alpha
so it must be the wrong tarball</description>

		<description>Hello
I don&#039;t know if it&#039;s a right place to ask for, but I need help to compile your software. (sorry if my english is not as good as I would like)

I was looking for a way to use smaart with wine, jack (works fine with alsa and my internal sound card but not with jack and my firewire card) and my 64studio/debian(amd64), and I found brp_pacu.  Great surprise!! 

I compiled libs with success, but when compiling brp_pacu, it ends with :

gcc -O2 -Wall -g  `pkg-config --cflags libglade-2.0`  `pkg-config --cflags gtk+-2.0` `pkg-config --cflags gdk`   `pkg-config --cflags gdk-2.0`  `pkg-config --cflags  gtkdatabox` -DDATADIR=\&quot;/usr/local/share\&quot; -g -O2   -o BRP_PACU testfft.o gui.o BRP_PACU.o   -lm -lpthread  -lfftw  `pkg-config --libs  libglade-2.0`  `pkg-config --libs  gtk+-2.0` `pkg-config --libs  gdk`  `pkg-config --libs gtkdatabox` `pkg-config --libs jack` -framework Carbon
gcc: Carbon: Aucun fichier ou répertoire de ce type    (!! means no such a file !!)
make[1]: *** [BRP_PACU] Erreur 1

And I can&#039;t find anything about something called &quot;carbon&quot;. Could you explain me where I should have a look.
Thank you and congratulations for creating such a tool.</description>

		<description>&quot;To comply with the license you must license your blog as GFDL, and attribute me as the author.&quot;

I have no problem attributing you as the author, but I have no idea how to comply with the GFDL, or if wordpress.com allows this.  Is there an example of another wordpress.com blog that does this?  Many of the pics I use came from wikimedia, and I would like to comply I just don&#039;t know how.

For example, I do somewhat know how to make my C code GPL v2 because there are other numerous other examples on the web, but since I&#039;m not a lawyer and do not want to consult one I used examples on the web to GPLv2 my C code.

Please point me to a valid example of a GFDL compliant blog I could use as an example?   Sorry I am not a lawyer and I don&#039;t have a lawyer.  I did read http://commons.wikimedia.org/wiki/GNU_Free_Documentation_License but it makes very little sense to laymen like me.  I also googled around a bit and couldn&#039;t find any examples.  GPL&#039;d code is much easier to find!

Also Is the GFDL the same thing as the &quot;Creative Commons&quot; license?

Thanks!
