Ah okay, my is this one here :
http://en.wikipedia.org/wiki/Sound_Blaster_Live!
Sound Blaster Live! Platinum, it's EMU10K1 based.

Hello all,
A long ago, I said on this list (I think), I had the intention to write
a graphical mixer/router for the EMU 10k cards (EMU 1212m & EMU 1616m).
I wanted to make a nice, well-written, full-featured app with routing
levels and eventually effects and all, but couldn't figure out all the
intricacies of the card's driver.
So, over the last two nights I hacked together a simple "Matrix"-style
app, very ugly in code, but functional, for me, at least.
I won't have time to maintain it, but if you want to try it out, at the
end of this message you'll find links to a screenshot, the source
package and an x86_64 build. You'll need Qt & ALSA libraries, of course.
Be aware that many features are missing, but basic routing works. I'll
put up a version control repo when I have time.
Any comments welcome.
Greetings,
Camilo

Hi,
I have issues with jack client names that contain whitespaces.
Example:
$ jack_connect MPlayer [19079]:out_0 system:playback_2
ERROR [19079]:out_0 not a valid port
Any idea how I can make this work? I tried:
$ jack_connect "MPlayer [19079]:out_0" "system:playback_2"
ERROR MPlayer [19079]:out_0 not a valid port
$ jack_connect 'MPlayer [19079]:out_0' 'system:playback_2'
ERROR MPlayer [19079]:out_0 not a valid port
So I wonder whether spaces in jack client names and ports are even
allowed, since imho jack_connect is a rather fundamental tool, and
either the tool or those clients are broken.

Geoff -- thanks for reporting this issue. It is a configuration
mistake in this release which doesn't show up in F12, which is what
I'm still using. Apparently, Fedora13 wants it to link with "-lm", but
F12 links happily without "-lm" ...So I never saw this
misconfiguration when I tested my distro build on F12...
As a quick fix, you should be able to link successfully by adding
"-lm" to the end of the linking command:
gcc -I/usr/include/gtk-2.0 -I/usr/lib64/gtk-2.0/include
-I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pango-1.0
-I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include
-I/usr/include/pixman-1 -I/usr/include/freetype2
-I/usr/include/libpng12 -I/usr/include/alsa -g -O2 -o
envy24control envy24control.o levelmeters.o midi.o mixer.o patchbay.o
hardware.o driverevents.o volume.o profiles.o config.o -lgtk-x11-2.0
-lgdk-x11-2.0 -latk-1.0 -lgio-2.0 -lpangoft2-1.0 -lgdk_pixbuf-2.0
-lpangocairo-1.0 -lcairo -lpango-1.0 -lfreetype -lfontconfig
-lgobject-2.0 -lgmodule-2.0 -lglib-2.0 -lasound -lm
The correct approach is to add "-lm" to the configuration files (i
thought i had, but mistakenly modified the generated file rather than
the configuration input files -- and "make dist-gzip" didn't of
course include my modification) ... I will need to fix this
build-blunder in the next release. Sorry.
If anybody has a suggestion on the most portable/reliable way of doing
this, please let me know.
I believe adding a line to configure.in-gtk2 like
ENVY24CONTROL_LIBS="$LIBS $ALSA_LIBS $GTK_LIBS -lm"
would do the trick, but you never know what happens to a simple line
of script out in the wild :-).
Is the above an accepted&proper way of adding "-lm" to an autoconf file?

On behalf of the guitarix team I'm proud to announce
Guitarix Version 0.11.1 Bug fix release
Guitarix is a simple Linux Rock Guitar amplifier and is designed
to achieve nice thrash/metal/rock/blues guitar sounds.
Guitarix uses the Jack Audio Connection Kit as its audio backend
and brings to the jack audio graph a mono amplifier input/output port,
and a FX mono input with two (stereo) output ports.
Guitarix provides a jack midi input port to connect a midi controller
(midi learn) and a (3 channel) jack midi output port, feed by a
(scalable) mix of the tuner and a beat-detector.
Release 0.11.1 comes with following changes :
* fix Bug Echo/Chorus/Delay/Slooper don't work
* add pre/post processing switch to all mono Effects
We put the Guitarix widgets into a library, with the goal of
making them usable independently from Guitarix. You can build
it as shared library and there's a c++ (gtkmm) wrapper, a python
wrapper and glade support. Check it out and look for examples
in those directories, or just build a nice looking display with the
glade editor, and of course ask in our Guitarix forum (it's still
alpha).
As a side note, Guitarix is now in debian(sid/squeeze/Experimental) ,
have fun

For capture, guitarix uses the great 'jack_capture'
(version >= 0.9.30) written by Kjetil S. Matheussen.

For extra Impulse Responses, guitarix uses the
zita-convolver library, and,
for up/down sampling we use zita-resampler,
both written by Fons Adriaensen.
If you don't have it installed, get it here:

We use the marvellous faust compiler to build the amp and effects and

the resulting faust cpp files to the needed include format,

Hi There,
Working on new version of APODIO http://www.apodio.org & wiki of the
work in progress http://www.apodio.org/wiki (please add ideas there if
you feel like!!)
I compiled monobristol (bristol GUI) and met the same problem as
falktx which to be around here.
the erro when starting monobristol is :
Unhandled Exception: System.NullReferenceException: Object reference
not set to an instance of an object
at MainWindow..ctor () [0x00000]
at monoBristol.MainClass.Main (System.String[] args) [0x00000]
I followed this message :
http://old.nabble.com/Is-anyone-using-monobristol-0.60.1--td29132285.html
(which seems to be the same everywhere)
I uptaded it with the repository of kxstudio... but same error...
did I missed something?
I used ubuntu 10.04
thanks for the answer

Folks,
I'm a recovering audiophile. When i was reading the magazines and
reading about over priced (in my now opinion) speakers, the words "full
range" tended to mean that a speaker was reasonably flat from 20 Hz to
20 kHz. Granted those were unusual.
I have read that speakers in an ambisonic set up should be "full range".
I'd like to set up a ambisonic speaker system (8 channel to start), and
the prospect of 8 full range channels is daunting. Since it seems they
would be stand or wall mounted (at least some of them) that means
monitors and subwoofers. Since all channels must be the same, that means
8 subwoofers...somewhere in the room.
So what does "full range" mean usually and what does it mean in terms of
talk on this list?
Thanks,
Bearcat
I just saw the announce on http://wiki.linuxaudio.org/
"We are looking for front-end developers, web-designers and
wiki-administrators to join in."
What kind of help do you need?
I mean, different from editing wiki content.
I could help with little graphics or web-design.
You could find me on freenode as 'carloratm'
Btw, i've just done these sites:

Hi guys,
Is it necc. for me to clamp my audio outputs to [-1.0, 1.0]?
Somewhere I got it in my head that I need to clip my output
signal (float*) to the range [-1.0, 1.0] before sending my
audio signals downstream.
However, this is a big time waster. When I review other
projects for efficient ways to clip... I can't find any.[1]
Looks like nobody's doing it.
Thanks,
Gabriel
[1] I found one in ardour, but it looks like it's just
for float->int conversion, and (possibly) not even
utilized within ardour.

A computer chip that performs calculations using probabilities,
instead of binary logic, could accelerate everything from online
banking systems to the flash memory in smart phones and other gadgets.
[...]
The electrical signals inside Lyric's chips represent probabilities,
instead of 1s and 0s. While the transistors of conventional chips are
arranged into components called digital NAND gates, which can be used
to implement all possible digital logic functions, those in a
probability processor make building blocks known as Bayesian NAND
gates. Bayesian probability is a field of mathematics named after the
eighteenth century English statistician Thomas Bayes, who developed
the early ideas on which it is based.
[...]
Lyric has been working on its technology in stealth mode since 2006,
partly with funding from the U.S. Defense Advanced Research Projects
Agency. DARPA is interested in potential defense applications that
would involve working with information that isn't clear cut--for
example, radio signals distorted accidentally or otherwise, and
machine vision systems that try to recognize actions or objects in
images. "They're interested in some James Bond-type applications,"
says Vigoda.
