Some new stuff on
<http://www.kokkinizita.net/linuxaudio/downloads>
Two new shared libraries:
zita-resampler-0.1.0
zita-convolver-0.1.0
Both C++. Unlike the libcl* series which are my 'personal
toolset' that I assume nobody will want to re-use, the zita
series of libraries will be fully documented.
The resampler already comes with HTML documentation, for
the convolver this is 'under construction'. This release
of zita-convolver is provided mainly as a dependency of
jconv-0.2.0
Command line JACK app for real-time fft-based partitioned
convolution with non-uniform partition size. Provides low
or zero delay processing at moderate CPU loads.
Any convolution matrix up to 64 * 64 as long as your CPU(s)
can take it. From the README:
New in this release
-------------------
- The convolution engine has been separated into
a shared library, libzita-convolver. For more
information on the internals of the convolution
engine, see the documentation provided with this
library.
- A non-real-time, file processing version of jconv,
called fconv, has been added. It accepts the same
configuration files. The input can be any file
readable by libsndfile. The output will be a 24-
bit WAV or WAVEX (for more than 2 channels).
- Large configurations requiring too much memory
will fail with an error message rather than just
crash with a segfault.
- Now uses jack_client_open(), so multiple instances
can be run even without using the -N <jack_name>
option.
- Optional use of FFTW_MEASURE.
- Added the mkwavex utility, converts multichannel
responses stored in separate files to a single
WAVEX file.
- New config files for some AMB reverbs.
The nicest one of these is York Minster, which
really sounds great.
Enjoy !

re all,
i urge you to take act against the exclusion of Ogg/Vorbis/Theora
audio/video streaming technology from the HTML-5 specification: this
exclusion will damage the efficiency of the world wide web in the
coming years by reducing the available protocols and codecs to the few
uncompatible and proprietary ones sold by business companies; at
present time it is clear that Nokia is being responsible of this
outrageous disaster as it untruly referred to Ogg as "proprietary
technology" addressing the W3C board on HTML5
http://www.boingboing.net/2007/12/09/nokia-to-w3c-ogg-is.html
Together with repeated attempts by other commercial companies to turn
down Ogg/Vorbis/Theora FOSS implementation for audio/video streaming,
we are witnessing the manipulation of what it should be a clean
evolution path for the biggest technological platform we all share.
http://yro.slashdot.org/article.pl?sid=07/12/11/1339251http://yro.slashdot.org/firehose.pl?id=419439http://html5.org/tools/web-apps-tracker?from=1142&to=1143
please help us build pressure NOW:
http://rudd-o.com/archives/2007/12/11/removal-of-ogg-vorbis-and-theora-from…
the W3C is supposed to be a "neutral" platform for development of
specifications, but on the contrary it seems to listen only to
business interests rather than citizens voices. Let's do everything
possible to recall the attention of civil society organizations to
what is happening, ASAP.
it is our responsability as netizens (citizens of the net) to raise
voices against this continuous ingerence of business interests into
the making of a viable platform for _horizontal_ communication in
civil society, offering an open access to its infrastructure. The
present unefficiency and incompatibility of multimedia communication
online is already the result of competition and unresponsability of
companies racing to impose their closed technologies on the market,
while the online citizens have the right for a common open source
alternative to all possible commercial products because communication
is a human right for all!
thanks for your concern,
la lucha sigue, tambien aqui', no estamos solos!
ciao

The Ubuntu Studio team is considering shipping Compiz (with a minimal
config) in Ubuntu Studio-Hardy 8.08.
Some have said that moving the drawing of windows off the the GFX card
would help the load on the CPU and thus keep xruns to a minimum.
Any thoughts/ideas on this one?

Hi...I have an M-Audio Delta 44 and am wondering if there's a way to
configure alsa/asoundrc so all audio is piped out via its internal
digital mixer, as opposed to PCM 1 and 2, an example: While skype can
use hardware inputs 1 or 2, if there is audio coming in on inputs 3
and 4, the audio for 3 and 4 is not sent through skype. Under Windows
various apps have the ability to choose which ins/outs to use,
including the use of the internal digital mixer. I can then have all 4
hardware inputs simultaneously being heard/sent over skype in Windows,
or dsp plugin in winamp.
I don't know if this is a lack of configuration, or driver limitation
in ice1712. I'm trying to achieve the same functionality under linux
as I do in Windows.
Also, would I need a sound server like jackd to achieve this
functionality? Currently I use dmix plugin in .asoundrc, but this
doesn't help with what I'm trying to do above.
.asoundrc:
pcm.amix {
type dmix
ipc_key 50557
slave {
pcm "hw:0,0"
period_time 0
period_size 8192
buffer_size 8192
}
bindings {
0 0
1 1
2 2
3 3
}
}
# route ALSA software through pcm.amix
pcm.!default {
type plug
slave.pcm "amix"
}
pcm.dsp0 {
type plug
slave.pcm "amix"
}
ctl.mixer0 {
type hw
card 0
}
----------------------------------------------------------------------------
Linux kernel 2.6.23 vanilla with alsa.
