Just realized that this also matters LAD members, so I am also forwarding it
to the LAD list.
Best wishes,

Not yet,
I initially misunderstood Paul by skimming over his e-mail that he wanted to
move the content. Now that I've figured that out, it seems that the only thing
we need to get the site linked is Paul's current URL/IP where he's hosting the
content. Paul?
Also, I am not sure what would be more effective in terms of linking
linuxaudio.org/developer or linuxaudio.org/lad. IMHO both have merit (the
first does not have any redundancy in its name, but the second one is more
accurate in terms of traditional LAD name). Perhaps someone else wants to
chime in with an opinion on this one, or should we simply link both of them
for the time being so that the site becomes available while we discuss the
details? ;-)

Hi,
on my quest to understand the ALSA API, I created a little Image to
get an overview about the various states and how they relate to each
other.

Hopefully I got everyting right, can you have a look at this image and
tell me whether this is correct?
Thanks

Hi,
I'm still trying to grok alsa, and now I have the following problem:
I'm using snd_pcm_writei to playback some audio, however, after a
little time the call fails with the error: "File descriptor in bad
state", which I believe I cannot recover from.
Why does this happen, and what could I do about this?
cat /proc/asound/card0/pcm0p/sub0/* prints the following stuff, I
don't know whether this is helpful?

Oh and i forgot to ask a question:
What is the canonical way for a gtk app to receive hotkey press events
regardless of window focus?

PDX7 V2
In 2001, I started learning Pd. The first bigger patch I did was a six
operator FM synthesizer loosely modelled after the famous DX7, which I
called PDX7. Now it's five years later and not only in retrospect
this first patch is quite a mess. But I still like the sounds it
generates. In the meantime I learned a lot more about Pd and about a
lot of other things. So I thought, why not celebrate the fifth
anniversary of me doing Pd, the fifth "birthday" with a cleaner
version of the PDX7, that maybe others can understand to use as well.
The result is the PDX7 V2.

Snd-ls v0.9.5.4
================
Contains
--------
Snd v7.15 from 17.8.2005
About
-----
Snd-ls is a distribution of the sound editor Snd. Its target is
people that don't know scheme very well, and don't want
to spend too much time configuring Snd. It can also serve
as a quick introduction to Snd and how it can be set up.
Changes 0.9.5.3 -> 0.9.5.4
--------------------------
-Changed default resampling quality to SRC_SINC_BEST_QUALITY
-Added workaround for shift-handling across various keyboard settings.
(shortcuts for zoom in and undo works with american keyboards now.)
-Added check for Guile 1.8. Snd-ls crashes with guile 1.8.
(all versions I have tried of 1.7 seems to work though...)
-Use JackPortIsPhysical instead of "alsa_pcm" when finding jack ports.
-Updated the rt stuff to latest versions.

Das_Watchdog V0.2.1
===================
About
-----
Das_Watchdog is a general watchdog for the linux operating system that
should be runned in the background at all times to ensure a realtime
process won't hang the machine.
Changes 0.2.0->0.2.1
--------------------
*Cleaned up source a bit.
*Properly find number of timer processes.
*Added shortcuts for optargs.
netjack-0.10 comes with a huge quality improvement to alsa_in and
alsa_out.
its now ready for prime time.
try alsa_out -f 10000 and listen...

http://galan.sourceforge.net -- The graphical Audio language
-- oops, the first one was sent as a reply, here's the whole thing as a
new thread.
frustrated by the poor implementation of the jack bindings for python
(pyjack), i wrote my own in native python using ctypes.
the first test client mixed a 440hz sine wave using native python lists,
and the cpu usage was about ~11%.
i reimplemented the sine generator with numerics, and got it down to
~2%.
i believe that considering the overhead of the python implementation,
that result isn't too bad, and maybe allows for more than just
prototyping.
i attached the jack wrapper with the test client contained for those who
are interested. its not entirely wrapped and lacks some functionality.

Hi all,
this mail is just to inform you that registration for the 4th International
Linux Audio Conference (or "LAC2006" for short), APril 27th-30th, in Karlsruhe,
Germany, is possible as of now by visiting our web page at
http://lac.zkm.de
and clicking on the link "Registration" on the left.
Like last year (and the years before), registration is free and is only
necessary because we need to prepare nametags, make estimations about
room sizes/required chairs and want to learn a bit about our audience.
That's all, honestly! :-). Information given there will NOT be used for
any kind of selling, spamming or otherwise abusing.
Also, the preliminary conference program has been published a few weeks
ago, available through the same link give above.
Thanks for registering in case you plan to come!
Greetings,
