Hello friends,
I just bought a Maudio audiophile USB, as I saw Alsa-project show it as
reconized by alsa... This soundcard is quite nice actually...and not so expensive...
So it's work with Alsa (I test 1.0.6, 1.0.8 and one of the lastest 1.0.9rc2), I
could listen music over xmms...
But when I want to use jackd (via qjackctl) there is no way to make it work, I
test different samplerate and other parameters, the problem is still here...
In the message box it says that jack tried different samplerate, but none of
them work with the cards...
I don't know if someone use this card or have experience with it, but as it
seems reconized by alsa maybe there is something special to do...? I don't know
if there is a solution somewhere, with the .asoundrc or...?
Thanks a lot for your help!!
cheers

You are right! The "midithrough" I was talking about was on the qjackctl gui.

Thank's, I'm gonna look around the alsa sequencer/midi stuff to get my system as I want it!

Ok this is where I have to look at!

Strange, but when with seq-0.6.1, when I start it before zynaddsubfx, zyn shows up in the otpions menu, but doesn't work... but it does with the latest version, so there is no more problem on this side
Thank's again.

Hi,
I have split up the first 4 performances into seperate ogg files, do I
need permission to upload them somewhere? I guess they would be best at
the linuxdj.com with the rest.
cheers,

re-Hi
Sorry to waste your time...
it works now: I got to start in the order: jack, then zynaddsubfx, and
at the end seq24.
I feel a bit stupid.
Anyway, I still like to know what is this midithrough... and how to have
with jack if it's possible.
Yves
again, sorry and thank's
Hi
Ok ok, I installed gentoo, I installed jack, I installed the realtime
module (it shows up with lsmod and in jack). But seq24 won't "work":
If I use seq24-0.6.2 or 0.6.3, then it won't even start, won't even show
in jack.
If I use seq24-0.6.1 it starts, but it won't show up in jack, or won't
find any apps like zynaddsubfx, but at least, seq24 starts with this
version when I press the play button (and the refresh button of jack
"blink" like it does on FC3).
When I use fedora core 3, seq24-0.6.1 shows up in jack through
"midithrough" and works fine. I don't really know what that is and how
to enable that...
What is this "midithrough" in jack, how can I manage to have it in the
gentoo's jack?
I would be happy to know the way to the solution (then I stay on Gentoo
forever... :-) )
Thank's
Yves
I am using RedHat 9.0. I have an Intel Sound card. The
volume of recording is very low and the default
installation of RedHat is giving an error in the use
of volume control.
Can someone suggest, what should be done to increase
he volume level of the recording. In MS Windows, the
recording level is OK.
bye

VisibleSound/AudibleImage is a workshop and performance series by Derek
Holzer and Sara Kolster which focuses on the interrelation of sound and
image.
The workshop component is a four day overview of Pure Data, GEM and PDP,
a collection of Free + Open Source Softwares available for Linux and Mac
OSX 10.3 which allow image, sound and data to be synthesized and
manipulated in the same environment. Participants will learn the basic
"grammar" and "vocabulary" of Pure Data, upon which objects for sound,
3D and video will be added. Emphasis will be placed on direct
connections between sound and image through three different methods:
influence of sound on image, influence of image on sound and the use of
common "control data" for both image and sound.
Time: 24. - 28. may 2005
Place: BEK, C. Sundtsgt. 55, 5004 Bergen, Norway
Free participation.
To apply send a short CV to bek(a)bek.no before 16. may.
Workshop Details:
*DAY ONE
1) Introduction: Why PD & Why Free + Open Source Software?
Our decision to use Pure Data has been motivated by several factors.
First and foremost is the need for a modular environment where audio and
video processing is possible without the intrusion of negative elements
such as a predetermined Graphical User Environment, cross-platform
issues and restrictive licenses. We will discuss these issues, and why
it is more important than ever that artists take Free + Open Source
Software seriously as tools for creative expression.
2) Installation Clinic
The first part of the workshop will be devoted to installing Pure Data,
GEM, PDP and several other externals on the participants' computers. Mac
OSX 10.3 and most Linux distributions can be accomodated. While PD and
GEM support Windows, PDP and several other externals do not, so Windows
users will be encouraged to use a live Linux CD such as Dynebolic during
the workshop.
3) Pure Data as a Language
Like learning any new language, PD starts with learning vocabulary and
grammer. In this case, we will learn the names of many common objects
and the syntax of how to use them, in a clear "Geek-to-English"
translation which makes the complex data-flow operations of PD
understandable to non-technicians and artists.
4) Pure Data for Sound Synthesis
PD has powerful signal-processing abilities, and we will explore these
by building a simple, monophonic synthesizer controllable from either a
MIDI device or from the keyboard of your computer. Different types of
sound sythesis, such as Additive, Subtractive, Amplitude Modulation,
Frequency Modulation and Wavetable Synthesis will be covered, along with
the use of filters and delays for a variety of effects.
*DAY TWO
1) Pure Data for Sample Manipulation
Because PD uses a range of very basic building-blocks to store and
playback sampled sound, a wide range of manipulations are possible.
Here, we will explore pitchshifting, time stretching, looping and basic
granular synthesis. Other uses of data stored in tables for control
purposes will also be touched on.
2) Pure Data for 3D: GEM
GEM is an external library used in PD for moving 3D graphics under the
OpenGL protocol. It is also an ideal environment for VJ mixing. We will
explore how to create and manipulate simple 3D objects, how to texture
them with images, how to playback and mix video clips in GEM and how to
use a live camera input.
3) Pure Data for Physical Modelling: PMPD
PMPD is an external library for PD which allows the creation of physical
models, consisting of units of mass and force, which can be used to
control both sound and image. We will look at different examples of
physical modelling using the sound-processing of PD as well as 3D
graphics from GEM to sonify and visualize our "virtual objects".
*DAY THREE
1) Pure Data for Audio Analysis
We continue our investigation of the audio side of Pure Data by looking
at different methods of analyzing sound signals for pitch and amplitude
information. The data we extract from the audio can be used to either
(re)synthesize new sounds or to control 3D or video graphics manipulations.
2) Pure Data for Video: PDP
PDP (Pure Data Packet) is another external library in PD which is used
primarily for video playback and effects filters. We will investigate
PDP for direct video synthesis, for the playback and mixing of
(audio)visual clips and for the processing of a live camera input. PDP
includes several tools for the analysis of video for movement, change
and color, which in turn can be used to control sound playback and other
events in PD.
*DAY FOUR
1) Pure Practical Examples
Now that the workshop participants have the background to understand
more complex PD patches, we will spend the morning looking at various
demos and performance patches to see how different artists and
programmers have developed their own environments for live audiovisual
synthesis.
2) Pure Data Practice
Workshop participants will put what they have learned into practice by
working in small groups, pairing sound artists together with video
artists to create simple audiovisual performance tools, with an emphasis
on the interrelation of sound and image.
*DAY FIVE
1) Workshop Presentation
Public presentation by instructors and workshop participants of tools
created during the week, covering the importance of Free + Open Source
Software, as well as the practical examples of its use.

"How would someone else do it?"
Hi all,
I am very new to audio/video domain. On one of my ARM board running
linux I need to have the IMA ADPCM decoder.
Can anyone tell me,
1) Is there open source decoder available.
2) some document/link that would give me basic understanding
about the audio/video architectue.
Thanks,
Prashant
Dear sir,
The HTPC market is growing and Linux has a strong presence here via
software offerings like MythTV (http://www.mythtv.org/). A significant
portion of HTPC users are interested in quality audio such as the one
offered by professionnal sound cards.
Simultaneously there is a drive to make kill all sources of low latency in
the Linux kernel (http://lwn.net/Articles/120797/) to accomodate
professionnal audio needs. Large professionnal Linux audio communities
already exist (http://jackit.sourceforge.net/,
http://www.linuxdj.com/audio/lad/) and the level of interest is high
enough to be seen by some as driving the next major release of the Linux
kernel
(http://www.computerworld.com.au/index.php/id;669959914;fp;16;fpid;0 last
§)
Current Linux sound card support is good for mass-market products and
high-end (RME, M-audio...) ones but no one has filled the intermediate
audiophile/semi-pro/home-studio niche yet. The E-MU 1212m
http://www.emu.com/products/product.asp?maincategory=754&category=754&produ…
would seem to be ideally positionned to respond to this demand on the
hardware side, except it has no Linux driver support right now. The Alsa
project (http://www.alsa-project.org/) however has expressed interest on
working on the problem provided they get an hardware sample.
Since Alsa already develops drivers for other Creative sound cards with
Creative support cooperating it would seem natural to expand the current
partnership to the E-MU sound card family. I hope I made the case for such
a partneship clear (I'm no native english speaker) and I'll soon be a
happy Linux E-MU customer.
Kind regards,
