Hi all,
This weekend, starting a midnight (EST), Saturday morning (Mar 9), the
Systems Support Group at Virginia Tech has scheduled storage maintenance.
The storage that supports linuxaudio.org will be unavailable from
midnight until noon Saturday (EST) and hence the server will be offline.
thanks for your understanding.

Hi all
I have just installed the lv2 GxAmps,
but when I run the plugins on jalv, some messages appears on the terminal:
"cabconv.update fail.
cabinet convolver disabled
ampconv.update fail.
presence convolver disabled"
Does anyone know how to solve this problem?

Hi all
i'm trying to sync arpage (jack synced arpeggiator) to Hydrogen:
in hydrogen i enabled jack transport + set hydrogen as master
Arpage gets triggered when i hit play in hydrogen, but it does not do what
i expect it to do (the tempo is all 'weird')
if i do the same with qtractor, ardour or the jack_transport utility as
jack master everything works as expected
now i'm trying to find an easy way to see if there is any difference
between the way hydrogen and the other apps start/stop/'master' the jack
transport, but so far i cant see any difference
is there any app/utility that can give me detailed info about jack
transport ?
i have logged a ticket (including a screen recording @ bottom of the
ticket) of this strange behavior :
https://github.com/hydrogen-music/hydrogen/issues/81
any tips ?
grtz

Hey all,
I'm currently attempting to stress test my setup of -rt kernel, rtirq
scripts, and a Jack client program I've been working on.
So my idea is to create a script that runs the programs, and also a
cpu-load generating program (cpuburn or alternative).
Then collecting stats based on Xruns, % DSP load, etc.
I intend to show (trough brute force) that an application is RT capable on
machine X with a latency of Y ms.
Of course this won't be 100% representative, but the stats will show some
RT-safe-ness.
Has anybody done this kind of profiling / stress testing with JACK before?
Hints / tips / advice / etc welcomed! -Harry
Hello Developers,
I have written a short blog post about what I think is the ideal license for open source sampled instrument libraries. It is in fact either a CC license or GPL, I am not so naive to think I am able to write an entire license, but I have added necessary additions and exceptions.
I am not a lawyer and I have no education or official background in law and rights. This is a suggestion, based on my experience with existing licenses and the requirements of sample based virtual instrument libraries, a.k.a "Samples"
http://www.nilsgey.de/2013/02/28/License_Proposal_for_Sample_Instrument_Lib…
I welcome any comments here or in the blog itself since I know that licenses are a serious matter. And I don't want to make a fool of myself. I remember some weird licenses, even in the linux audio community, and I don't want to create one of them :)
Greetings,
Nils
Ignorant here. Trying to scrounge around and make something work for a demo
purpose.
In python I am trying to build this pipeline:
pipeline_txt = (
'jackaudiosrc ! '
'level name=level interval=1000000000 !'
'jackaudiosink')
pipeline = gst.parse_launch(pipeline_txt)
I have been trying that a number of ways.
So, I basically watch the bus for level info.
In a subroutine, I can print the peak info to the terminal.
I can't seem to figure out how to pass this info back to the rest of the
program so that I can hook it up to a graphical meter.
Cna anyone point me to some simple code doing something like this? Give me
some clues that might help someone who seems to be being very dense for days
now?
all the best,
drew
Hello all,
we are working on some development of audio/video web live
applications at the moment. We are facing a little problem, maybe some
people here already came across. Some people advised us to use red5,
an audio/video streaming and multi-user solution to take sound from
mic / sound card input + webcam/cam to be streamed online via your
browser. The biggest problem we are facing is that is based on adobe
closed flash system and it use only proprietary format/codecs such as
mp3, flv and h264 :-(
We are looking for a way to do the same with floss technologies such
as ogg, theora, icecast or others...
The idea is that the final user will stream his sound and video with
his browser and everyone could see/hear him and do the same via their
browser.
We are actually testing some solutions with gstreamer but we still
need an external client, although we are thinking about using some
python script to run on the server to handle gstreamer live stream...
but we are not sure...
Anyway if any of you have any hints or some floss solutions for that,
it would be really highly appreciated :-)
thank you
cheers
Julien
