Maybe you should ask this to the alsa-devel list too. I think Paul Davis
could be interested in doing this kind of job. I'm interested too.
I worked on the hdsp driver and helper apps mainly because I owned a
Multiface
and wanted to use its full potential under my favourite and now only OS...

Hi, I very interested into DSP modelisation techniques
and more precisely about Guitar preamps modelisation techniques.
Anyone have some resources, any SoA / Paper related to this subject ?
As an example, I would like to understand what dsp underlying techniques
use successful effects like :
- the Amplitube VST software effect on mac/pc plateforms
- For hardware effects, the Pod guitar effect from Line6
TIA.

Hi,
I'm pleased to announce the first public release of hdspmixer.
Hdspmixer is a linux clone of Totalmix, a tool to control the
advanced routing possibilities of the RME Hammerfall DSP cards.
You can donwload hdspmixer here :

Hello Debian users and interested bystanders,
I have completed the Debian csound package. Once my sponsor has looked
it over, approved of it, and uploaded it, it will be in unstable. In the
meantime you can find it at
deb http://hans.fugal.net/debian sid/main
deb-src http://hans.fugal.net/debian sid/main
I use csound, but I wouldn't consider myself a power user; in particular
I haven't used any of the utilities (e.g. pvanal, hetro, etc.). If you
do use them, please give the manpages a look-over and let me know if you
see anything wrong.

I'm a professional audio engineer for 15 years, and DSD did convince me. I
could compare the sound quality with TI ADC/DAC.
Conventional PCM techniques are unable to reproduce high frequencies
correctly. And the explanation is very simple. If you record a sound at 44.1
kss, you get a theorical frequency response of 0 - 22050 Hz. BUT to describe
frequencies from 11050 to 22050 Hz, you can only play with a 4-sample long
period.
A 22050 Hz sine could be really accurate (one sample up, one sample down
every 1/22050th second), and so is 11025. But intermediary frequencies
introduces temporal aliasing, some metallic feeling due to temporal
quantization. This is inherent to the very low sampling rate (96 kHz is just
a bit better, but no miracle), which is unable to describe waveforms at high
frequencies.
Bad high frequencies temporal definition means bad transients. Anyone can
notice it when he _actually_ hear and compare PCM and DSD.
Stop speculative talking and try to get some real demo...

Dear Sirs, dear Madams
I've programmed an utility called kisdnmonitor, it tracks the calls you make/
receive. It's for KDE as the name suggests. There's a server as well, it's called
isdnserver. You can get more infos on both on:
http://www.elogix.ch/linux_en.html
Now I would like to add telephony support to the programs, so that you can use
the computer as a "deluxe" isdn phone.
So far I've figured out that you can dial through the modem emulation /dev/ttyIx.
You just properly configure the device and then with the following Hayes codes:
ATS18=1
ATS14=4
ATD<the phone number>
you can start a call.
Everything is ok so far, the problem is that, obviously, no sound will automagically
come out from the speakers and nothing that is brabbled through the mic will go to
the other side.
Basically, what I want to do, is to stream the sound from the isdncard to the speakers
and from the mic to the isdncard. Vbox (a voice call programm) is able to save samples
from the isdncard's input. I should mention as well that years ago, I had a program that
came with the isdncard (for windoze) called RVScom that had the same functionality,
and it worked (in walkie talkie mode, I guess that my isdncard isn't full duplex capable).
Since 8 bits suffice, the processor load shouldn't be extreme.
Has anyone an idea?
Any help would be greatly appreciated. Thank you in advance

Hello list,
I hope there are some other users of the Terratec EWS88MT card out
there, because I seem to be in serious trouble - the card 'works'
but not in a way that makes it useful.
I've got a test program that outputs the same signal (1 kHz sine at
-6 dB below peak level) to all eight channels. Measuring the output
levels, I get wildly different values. Using envy24control to set
the DAC output levels only seems to make things worse - there is
no logical relation at all between the slider position and the
actual level. For each of the four pairs of channels, the two
level settings interact in a more or less random way, mostly by
just switching the other channel off or on. After a few minutes
twiddling, all sound stops until I reboot.
Similar things seem to happen with the inputs, but I haven't had
the time to investigate those.
So I'm wondering what's wrong - is my new card not up to standards,
or is there a problem with envy24control trying to control it ?
Any help / hints / tips appreciated !

So, there is no "do not optimize away apperent volatile variables"?
Volatile variables in shmclient are easily recognized -- at least
I recognized them. It is the array variable which content is only
read but never written.
No such optimization flag? Can't believe that compilers are that dump.

Hi!
gmorgan is a .. Rhythm Station, an organ with auto-accompaniment and a "small"
Band in a Linux Box. Uses MIDI and the ALSA sequencer for play the rhythm
patterns. Styles, patterns , sounds, and the mixer settings, can be edited
and saved.
Program is released GNU/GPL version 2.

Take a look at http://personal.telefonica.terra.es/web/soudfontcombi/
And please ... if you enjoy this prog and wants to share patterns, send me,
and i will include in future versions, i have a large TODO, and i need some
help.

Greetings:
I couldn't find the answer to this one on Google, so:
Which Linux distributions include wxWindows in their default
installations ?
