My blog on Linux audio and video work got linked from linuxaudio.org,
thanks a lot for this!
Nonetheless I finally agreed with Xabi, webmaster from Hispasonic, the
main site in spanish devoted to audio production, to use my blog there
to include my articles on audio work using GNU/Linux. That site has a
lot more audience and it's lovely targeted by Google which is a very
nice thing for a blog writter.
So I closed Linux AV and I would be glad to have "my" link at
linuxaudio.org modified.
The previous link was "Linux AV" pointing to http://linuxav.blogspot.com
The new link could be "Linux audio at blog ivalladt" or simply "blog
ivalladt" pointing to http://www.hispasonic.com/blog/ivalladt
Thanks in advance and please keep doing such a good job everybody! :)
Cordially, Ismael

Hello all,
Some updates on <http://www.kokkinizita.net/linuxaudio/downloads>:
jmeters-0.2.0
- VU-meter scale replaced by a new one which does
not have the -20dB threshold. Now it will also
move for low-level sounds, and fall back much
more naturally.
- PPM now has the same size as VU. Old one still
available as ppm2.
- Added options to set jack client name and update
rate.
- Bugfix for Makefile, PNGs now get installed in
$(PREFIX)/share instead of /usr/share.
aeolus-0.8.1
- Aeolus-0.8.0 added Midi over Jack support but was
announced on the Aeolus list only IIRC. With 0.8.1
it's official.
- Major cleanup and bugfixes.
- Replaces 0.6.6. as the supported release.
ambdec-0.2.0
- Bugfixes, new collection of config files.
MCP-plugins-0.4.0
- Major cleanup (after 5 years or so).
- Added triple chorus. Same as chorus2 but has three
outputs. Pan L,C,R for a nice stereo effect.
clthreads-2.4.0
- Cleanup.
clxclient-3.6.1
- Cleanup.
- Probably fixes a bug that occurs only when running
in KDE (windows not repainting when exposed).
Many thanks to all who contributed by providing feedback,
bug reports and patches.
The two libs and ambdec now also have an OSX Makefile and
the necessary #ifdefs to make them compile. This is very
experimental. I will provide *no* support for this except
to OSX developers who can provide the required technical
feedback.
Ciao,

Hi there, whoever maintaining this page:
I miss www.jacklab.org in the list -I know that most of you don't like
openSUSE because of the "evil" Novell - MS contract, but we (jacklab)
are independent from Novell and a serious audio distribution project,
which made already some contributions for the community.
Could be someone be so kind and make an entree for www.jacklab.org ?
Regards,
Michael
The first (beta) release of Jmeters is available at
<http://www.kokkinizita.net/linuxaudio/downloads>
Jmeters is a Jack multichannel audio level meter app.
It looks very similar to meterbridge since it uses the
same pixmaps.
This first release offers VU, PPM and stereo versions of the
same. The stereo versions have two indicator needles on the
same scale. I've never seen a twin VU, but stereo (or M/S)
PPMs *do* exist. Later releases will add bargraph meters,
digital peak indicators for the analog ones, and a stereo
correlation meter.
The main difference to meterbridge is that Jmeters has the
correct ballistics for both the VU and the PPM.
The VU meter measures the average of the absolute value of
the signal, 'average' meaning a second order filter that
reaches 99% in 300ms and overshoots between 1.0 and 1.5%.
It is calibrated to indicate 0dB for a sine wave at -10dB
w.r.t. digital full scale (which is +/-1 peak in this case).
The particular VU scale used is not entirely linear and
starts at -20dB (it's one designed for a passive VU meter
with a diode bridge), so the meter will not move at all
for inputs below that level. Later versions may use a
VU scale designed for an active meter which doesn't have
this threshold.
The PPM is a pseudo-peak meter. It will indicate 80% of
the steady-state value for a 10ms burst, and fall by 24db
in 2.8s. Each scale division (1..7) represents 4dB. It is
calibrated to indicate '7' (+12 dB on the EBU scale) for
0dB FS.
For speech and music with distinct short peaks the PPM
will usually indicate higher. For music with continuous
long notes, and for heavily compressed signals the VU
indicates higher. Both meters require some 'getting used
to' in order to read them correctly.
You can modify the calibration by using the -g(ain) option,
but it should normally not be necessary.
Enjoy !

I certainly agree some consolidation could be a good thing. What I am
wondering about though, is the possibility of truly using the linuxaudio.org
as a portal. In order to do this I think several things would be needed
from my standpoint....
See http://portal.linuxaudio.org <http://portal.linuxaudio.org/>
1. A centralized basic information about all applications (wiki already in
existance, good start)
http://apps.linuxaudio.org <http://apps.linuxaudio.org/> has all apps that
have been a part of Dave's website. They can be also sorted according to
jack/ladspa/whatever support and entries are open to community
contributions. There were a number of people here very vocal how they would
not contribute to a wiki that was password protected. Well, it hasn been
open access since its introduction little over a year ago, yet we had little
or no contributions since. It would be nice if we would be as determined
about our contributions as we are about our preferences, no?
2. A centralized repository of general linux audio information(ie What is
realtime, why/when should you use it, FAQs etc.)
http://lowlatency.linuxaudio.org/ (yes, it could be much better, volunteers
are always welcome)
3. A centralized place to go for announcements from all projects at once...
http://lists.linuxaudio.org <http://lists.linuxaudio.org/>
we are hoping to also implement forum.linuxaudio.org
- This would likely entail using a RSS feeds for all members of the
linuxaudio consortium, and subscribing to those feeds to be displayed on the
news page. I am sure there is a better way, but this is what sticks out to
me at the moment, filtering of the announcements might be necessary. I
suppose another option would be to utilize the linux-audio-announce mailing
list instead so as to have a natural filter preventing things like general
informational posts.
Linuxaudio.org main page has RSS feeds.
4. I am not against a centralized forum either, however I think app specific
forums and websites are still a good thing, which leads to the next point
couple of points...
5. Tight integration between all of the above. On the wiki we have links to
the forums for those peices of software, or from the FAQ/Info sections links
to the forums, or from the Forums to the wikis, with the news announcements
a link to the wiki for the software the announcement is about, etc.
This is in progress but again, most of the work you've seen so far has been
the fruit of maybe half-dozen people including myself.
6. A single login for linuxaudio... And I don't just mean linuxaudio.org,
but all member projects if possible. This is the one most difficult to
implement, and probably most contreversial, but would allay some of the
problems that Dave and others have, which is having to sign up for hundreds
of forums with logins to remember etc. Having one place to go for that
would be great. This could tie into the centralized forums, by having
direct links to each of the projects individual forums, if applicable, and
auto-login. OpenID is making good strides in this area, but as I mentioned
I do expect this to be the most contreversial of my suggestions I suppose,
along with still being the most difficult to implement.
See above. Some users complain about having to log in so we left it open for
the sake of greatest possible target audience.
Best wishes,
ico
But the goal with these would be to provide a single portal, from which you
can get all levels of help by utilizing all the availiable resources out
there.

The 1.0.10 package released a few weeks ago seems to have some packaging
issues (missing files etc...). Therefore a new package has been uploaded
that should fix these issues.
Available at sourceforge:

Relaying some great news from Felipe Sateler, on debian csound packaging.
Felipe has been working hard to create an official debian package for Csound
and it seems like he succeeded.
=========================================================
So, it's official now. I have just received the ACCEPTED mail from the
ftpmasters, which means that csound should be available in your local debian
mirror real soon now (ie, as soon as it gets autobuilt and the mirrors
synched).
Ubuntu will follow soon too.

I think this is also the greatest ailment of the Linux audio community.
Perhaps it stems from the fact that everyone is excited about the 2%
inspiration new project offers but is taken aback when the first 2% finally
disappear and one is left with 98% perspiration. Such projects never go past
the 0.3 version and eventually join the endless ranks of "potentially really
cool but totally buggy and unfinished" software tools.
This is why I've been lobbying hard to get all the online resources into one
place. That's why we have apps.linuxaudio.orgdocs.linuxaudio.orglists.linuxaudio.org etc. (yes some of these are placeholders waiting for
users to contribute). We need more perspiration than inspiration at this
point as that will be the only thing that will bring us closer to some of
the noble goals mentioned here.

Hi,
A friend of mine just showed me that there will be a german
open source expo. I already wrote on the german linux audio
board in case somebody wants to take part as a project (probably
a booth).
Unfortunately it is really close to the Berlin Linuxtag 2008,
so it is probably mainly interesting for those living in the
south of germany.
As many audio developers and users live in south germany I hope that
someone is willing to make an LinuxAudio/JackLab/Studio64 or whatever
project booth.
Kind regards,
Reinhard Katzmann
