Hello,
I want to highlight this bug, even if many probably know it, because
it is absolutely to avoid in a sound machine.
In another thread "[LAU] ardour3 on debian stable" [1]:
> Unpacking ardour3 (from ardour3_3.5.74~dfsg-1_i386.deb) ...
> dpkg: dependency problems prevent configuration of ardour3:
> [...]
> ardour3 depends on libc6 (>= 2.17); however:
Some libraries employed by ardour (for example rubberband, vamp-sdk
and qm-dsp) use sin|cos|exp from `libm'. There is a degradation of the
performance (3:1 in my code for sound synthesis) caused by a bug in
glibc 2.17 (more info here [2]).
Some distros are updated (for example fedora [3]) but in some cases,
one is the last slackware 14.1, it is necessary to recompile the
sources after the application of the patch.
For debian users: I don't see the patch in 2.17-97 [4].

I'm interested in using one with both the Linux box and a mac mini.
I currently already run Ubuntu 11.10 on an older Visio of some sort.
F.lux doesn't run on it. Not too sure why. Seems like a hardware issue.
I kinda like the big, big-screen aspect but the TV-Monitor combo is
ridiculously bright when up close and personal.
I use Ardour a bit and lurk on this list like a mofo. Hence my question
here.
Thanks!
I have one of those cheap little sound cards which look like a
telephone handset which I've been using on my wife's computer. Had it
plugged into a USB multiport. Worked without a problem .... until
recently. The speaker worked just fine, but the microphone refused to
work. And when I say that it didn't work, it was completely dead. Mind
you both pulse and alsa found the mic just fine. I thought the unit
was buggered. After all, it's just a 5 or 10$ device.
But, I tried it on my computer and it worked fine.
Hmmm .... now I get to debug!
Figured it out after a few hours :) We'd only recently plugged her
mouse into the same multiport. If the "telephone" is plugged into a
different port, it works. If the mouse is not plugged into the
multiport, it works.
So, the problem turns out to be that having a mouse and the microphone
on the same multiport caused the problem.
Posted here so someone else can save a few hours :)

Hey All,
I'm delighted to say that 5 days after announcing, Luppp has reached its
target donation!
That means that its now available under the GPLv3+ license, to everybody!
Grab the details & source from here: http://openavproductions.com/luppp
I'd like to thanks the community, for the awesome support Luppp has
recieved!
Thanks to LeatusPenguin, ZthMusic, AutoStatic, and others for beta-testing,
making this release much more polished before this release. Thanks to
Jonathan Liles for writing NTK, the user-interface toolkit behind the
OpenAV software interfaces.
Thanks to all the contributers: you are the reason this software is
available right now!
Thanks again, -Harry

Hi all,
I have just published aubio 0.4.0~beta1. It would be nice if some of you
could give it a go before I push the final 0.4.0.
It's available here:
http://aubio.org/pub/aubio-0.4.0~beta1.tar.bz2
Here is the ChangeLog entry:
* Overdue: After more than five years of development behind the curtain,
time has come to release a new version of aubio.
* General: The library has been completely revised since 0.3.2. The API has
seen a major clean up, and has been thoroughly tested. The following list of
changes is not exhaustive.
* Memory management: allocation and freeing of memory has been optimized in
many ways. Several memory leaks and out of bound access have been fixed.
* Optimization: the FFT, central to most algorithm, can now be computed
using different optimized algorithms, depending on what is available on your
platform (FFTW, Ooura, or vDSP). Other simple optimization tricks are
included. Most can be deactivated by configuring the build accordingly.
* python/: The python interface has been completely rewritten to use numpy C
interface, making the aubio python module order of magnitudes faster than
the previous version. Several demos and tests are included.
* src/: source and header files are now organized in sub-directories.
* src/io/source.h: new source readers can now use any or all of libav,
CoreAudio, and libsndfile. This means that aubio can now easily read most
uncompressed and compressed formats. Compiled with libav, aubio can also
read audio from video files, and over the network.
* src/io/sink.h: a new sink object lets you write wav files with any number
of channels, at any samplerate, using libsndfile or CoreAudio.
* src/onset, src/tempo/, src/pitch: the different methods for onset, tempo,
and pitch extraction have seen many bug-fixes and optimizations.
* src/spectral/specdesc.h: new onset distances and statistical measures have
been added.
* src/spectral/filterbank.h: new filter bank to compute the energy in any
custom-defined frequency bands.
* src/spectral/mfcc.h, examples/aubiomfcc.c: a standard implementation of
the Mel-Frequency Cepstrum Coefficients algorithm has been added.
* src/temporal/{a,c}_weighting.h: standard implementation of the C-weighting
and A-weighting pre-processing filters are now provided for most commons
sampling rates.
* src/synth/wavetable.h, src/synth/sampler.h: provide basic ways to generate
some sounds.
* src/fvec.h: fvec_t, the vector object central to most aubio algorithms, is
now single channel. This simplifies the code of each algorithm greatly.
* src/lvec.h: lvec_t provides a double precision vector, required for some
operations to avoid floating point overflow
* src/fmat.h: fmat_t provides a single precision matrix, useful for
multi-channel operations and to some algorithms such as the spectral filter
bank.
* examples/: several new options, including new programs, have been
included. Refer to the documentation for details.
* tests/: several tests and examples programs have been added. This should
be a good place to look at to understand how to use aubio.
* doc/web.cfg: a simplified Doxygen configuration produces a simpler html
documentation.
* doc/*.txt: the manpages have been rewritten for txt2man.
* Build system: the build system has been switched from autotools/automake
to waf. Type './waf' or see README.md for instructions on how to use waf.
Questions and comments welcome!
Cheers, piem
Hello,
The Issue (jae ho youn + sergio millan) finished a month long residency @
the Labirynt gallery in Lublin, Poland.
as the outcome, we made a DMX light + sound installation in the cave and AV
concert, some graphical works generated by sound.
all the sound that you'll hear is 100% Linux. worked on (still!) ubuntu
10.10 and supercollider 3.4.
the visuals are done with OpenFrameWorks.
DMX installation is done by supercollider and processing.
these works are documented on my blog, so please take your time and check
them out, you won't be disappointed, I promise.

Thank you very much.
sincerely,
jae ho youn

Hi All. For those of you who like classical music, here's another piece recorded with Aeolus, MIDISH, and Nama. This is for Advent: "My Soul Exulteth The Lord" from the Schubler chorales by J S Bach.
https://www.dropbox.com/s/fs20gpdzxftxkz2/Bach_MySoulExulteth_1.mp3
If this doesn't open and play directly from this link, you should get to the dropbox page, where there is a download button. If you have problems, please let me know, as I'm still trying to figure out dropbox links. Please feel free to share it with my name attached, and any feedback you have is welcomed. Enjoy!

SiSco.lv2 a Simple Oscilloscope LV2 plugin for scientific measurements.
source: https://github.com/x42/sisco.lv2
manual: http://x42.github.io/sisco.lv2/
I recently had a need for a proper software-oscilloscope and there was
also the the case about providing a LV2 example to transfer Arrays of
LV2-Atoms. The latter is now available as eg05-scope.lv2 from lv2plug.in
"Gentlemen, when two separate events occur simultaneously pertaining to
the same object of inquiry, we must always pay strict attention."
(Dale Cooper)
SiSco is not a waveform display but an audio scope which accurately
reproduces the signal up to a maximum resolution of about 1μs/pixel
@48KSPS (corresponding to 960KHz resolution) to facilitate
measurements of an audio stream.
While it may seem advanced, it is still rather simple compared to
current technology hardware oscilloscopes:
* 1-4 channels
* grid-resolution min: 50μs, max: 1 sec (max buffer time 15 sec)
* per channel horizontal & vertical offset and amplitude scaling
* automatic and manual trigger with optional hold-off
* two time-axis cursors (shared among channels)
* numeric readout (RMS, P-P, dt) per channel
* display memory (freeze display - not acquisition - of any channel)
It is already available on various GNU/Linux distributions (although
maybe not yet the latest version) as part of the "x42-plugin" bundle.
Cheers!
