Hallo,
This is a serious question for Linux Audio and in general multi media
applications developers.
I am in the program committee of the conference part of a Linux related
even in france (called Salon Linux), and we are discussing about the
2010 conference program.
I may be in the condition to have a Audio or multi media subject added,
but i can do that only if i have serious evidence of a user base or
a developer base in france. Most of the subjects are around enterprise
and industrial development.
The conference is strictly french-speaking, and the access is not
for free (even if the organisation is stricly on a volunteer base).
So, any French developers here, and any evidence of a French user base ?

I'm looking for some real time audio analysis software similar to the
melodic range spectrogram in sonic visualizer. Instead of visual output
though, I'm looking for midi output (this can be rough, i'm not going to be
generating audio from it, just trying to check if said notes were played).
I'm not sure if this is possible with clam, I've used it a little, but not
much.
The ideal solution will be multiplatform.
Thanks for any leads,
Nathanael
Hi everyone, I'm wondering what most linux audio developers think about
pyqt vs wxpy for writing audio app guis now that qt is gpl'd.
Specifically I'm interested in tightly controlling the timing of event
loop ( ie making some accurate external clock source like the csound
engine be the time boss ) and making decent faders widgets.
thanks!

Hey guys,
I had a performance the other day with a nicely underpowered PC (500 MHz).
One man show. Everything being run through JACK (guitar + vocals), using
sooperlooper, and jack rack plus some nice TAP effects (for vocals). Set
up for 10ms latencies.
Not long into it I looked at the computer and saw the hard drive light was
very bright. Great. My computer is running updatedb... _now_??? This is
bad. Since I was doing something slightly different... I really couldn't
afford any glitches. So, I was a little nervous.
But I trudged along. No crashes. No xruns. No clicks. No problems.
So, I'm taking a moment to say: Thanks, everybody.
Peace,
Gabriel

As I'm new to smart pointers and memory management in C++ I have a short
question on this topic.
I'm now using the following code to traverse the devices and their ports:
snd_seq_client_info_t *clientInfo = 0;
snd_seq_port_info_t *portInfo = 0;
snd_seq_client_info_malloc(&clientInfo);
snd_seq_port_info_malloc(&portInfo);
shared_ptr<snd_seq_client_info_t> clientInfoMemoryHandler(clientInfo,
snd_seq_client_info_free);
shared_ptr<snd_seq_port_info_t> portInfoMemoryHandler(portInfo,
snd_seq_port_info_free);
.
.
.
snd_seq_port_info_set_client( portInfo,
snd_seq_client_info_get_client(clientInfo ) );
snd_seq_port_info_set_port( portInfo, -1 );
while ( snd_seq_query_next_port( seq, portInfo ) >= 0 ) {
string portName = snd_seq_port_info_get_name( portInfo );
unsigned int capability = snd_seq_port_info_get_capability( portInfo );
.
.
.
Well the cleanUp methods are called at block-leaving.
I'm only a bit curious because after giving portInfo and clientInfo to
the shared_ptr for cleanup management I have to use them for all the
alsa queries.
But since I'm not using malloc and free in these queries everything is
ok, isn't it?
Thanks for your help!

Hi,
There are quite some people who like to have a better Lilypond MIDI
output. But they lack some people who are able and want to work on it.
That's why I send this message.
There are some improvements using the Articulate midi script:
http://www.nicta.com.au/people/chubbp/articulate
And suggestions are made to use Midge, Mididings or Midicomp in some
way, to improve it.
If you're interested to contribute, please mail to the Lilypond mailinglist:
http://lists.gnu.org/mailman/listinfo/lilypond-user
Thanks in advance,
\rooz
I can't quite figure it out, can anyone tell me the circumstances that would
lead to jack reporting a change to samplerate/buffersize on the fly?
cheers, Cal
hi,
The buzztard team has released version 0.5.0 "crown of thorns" of its
buzz-alike music composer. All modules got extensive improvements over the last
release from almost a year ago. Give it a try, join hacking and report bugs.
bml
--------------------------------------------------------------------------------
Split the api into library and instance api. Lots of code and build cleanups.
bsl
--------------------------------------------------------------------------------
Several bug fixes and better compatibility.
buzztard
--------------------------------------------------------------------------------
Rewrite of internal pipeline management. One can now play partially connected
songs, and add/remove plugins while playing. Buzztard can play notes while
editing. More robust saving of songs. Lots of bugfixes and UI improvements.
Better user-guide including three small tutorials. Initial support for python
and javascript via gobject introspection.
gst-buzztard
--------------------------------------------------------------------------------
Lots of improvements in the buzzmachine wrapper. Buzz index support for
categories. Make machines live-playable. More resource efficient.

Hi folks, I have done any linux audio dev in a few years, and wondering
what I should be using for a simple cross-platform real time capable
python library for handling midi. I was previously using portmidi, but
noticed there has been more recent releases of rtmidi. Any advice
appreciated.
thanks

Hello everyone!
I have a problem and I'm not sure how to solve it in an optimal way. I have
several threads running.
1. An input thread (computer-keyboard/mouse)
2. An output thread (monitor other devices0
3. A working thread (the engine)
Now I wondered, what is the most efficient way to write the loops for the
input and output threads in a way, that they are always ready to accept
something coming.
I thought about something with signals, which is fine, as far as the output
is concerned, but the input comes from the user and only the device gets it
coming first and it can't really send a signal?
Any tipps, good guide or constructs, which have proven to be efficient?
Please/
Best regards
Julien
