Hi,
I ran accross a kernel module/tool titled irqtune.
>From it's web page:
#How do I know if I need irqtune?
<snip>
# Interrupt handlers for specialized, time critical
devices don't get control when they need to.
Perhaps it's just what the realtime audio admin needs.
I don't recall reading about it in our mailing lists.
Has anyone else looked at it? Thoughts?

Thanks!

I suggest a time of 1pm on Tuesday 15th, unless anyone has any better ideas.
Then we can make it an informal lunchtime meeting.

hello
im looking to try my hand at some midi programming - what, in your opinion, would be a simple starting point for midi + X programming?
I have experience in several languages but am at a loss as to which language to use with what lib and wondered what a simple starting point might be that still yield reasonable results. I would not be attempting anything to tricky ;)

Actually, this isn't quite correct. There are times when you want to
process the amplitude of one signal (eg a bassline) with the dynamics of
another (eg. a drum beat). Its pretty cheesy, but I dont think preventing
things on aritstic metrit is a good precident ;)

I was refering to gain reduction meters, which are simply a way of giving
the user a clue (warning) what is going on, hence the distinction between
that and an signal output.

I think you mean makeup gain here. Its genreally used to boos t the signal
level given a particularly heavy compression, but hypothetically you could
use it to reduce too.

Hi,
I'm building a new low latency + preemption patched
machine. I've forgotten how to confirm that the kernel
is running preemptively. It's a command to the effect
of 'cat /proc/something'. Anyone know what I'm
referring to?
Also, can someone point me to docs for enabling/using
a capabilities enabled kernel? Enabling normal user
capabilities for jackd is my objective. I believe
Fernando has this included in the CCRMA stuff but a
quick google didn't find any docs. They're probably
there. Hints appreciated. I'll search LAD
archives...it's probably all there.
Jan, your link to Paul Winkler's Low Lowlatency docs
at boosthardware are brooken.
Thanks,
ron

Hi,
Ardour recently added a feature for time stretching audio, which as I
understand it, was Open Source code from somewhere else. I have about
2000 Acid Pro loops that would be more useful to me if they had slightly
different properties than they were shipped with.
Is anyone working on a batch processing mechanism for dealing with
many, many wave files? Sonic Foundry offers this in their programs. Is
there any equivalent in Linux. (I'm not talking about writing scripts or
bash processing or anything like that.)
Thanks,
Mark
Hi all,
I'm having some trouble using my card's (Terratec DMX 6Fire 24/96) front
panel. When I plug my turntable to the phono connectors in the front panel,
I can hear the record playing, but I'm unable to record it. I try to record
with Audacity, tried all possible combinations in the Patchbay / Router at
the envy24 control panel, and nothing's getting recorded. I'm using SuSe 8.1
with kernel 2.4... any clues?
thanks!

Greetings:
Sorry to be a pain, but I'm having so much trouble installing and
configuring Mandrake 8.2 that I'm beginning to doubt whether it can be
done. Here's a partial list of my trials and tribulations:
1. The CD drive is actually a Toshiba DVD drive. Mandrake installed all
right from it but afterwards is unable to read from any disc I insert.
All I get is an uninformative "input/output error".
2. The sound configuration is a joke, right ? I boot into KDE and hear
the KDE tune just fine, but when I try to run any bundled sound
application (XMMS, MIDI synth, etc) I get an error saying that the
output device is unreachable. When I test sound using the Drake tool it
says it's playing an 8-bit sample but I hear nothing. The tool asks only
if you do or do not hear the sample, it offers no advice on what to do
if you don't hear anything.
3. The Internet configuration informs me that I have no connection even
when I do.
4. The GCC 2.96 is weird, yes ? When I ran ./configure for the latest
ALSA I get an error telling me that the C compiler cannot produce
executables. This, whether I'm normal user or root. Whafug??!!
So is it just me or are these well-known problems with Mandrake ? I'm
setting up two machines here, both experience the same problems with
Mandrake 8.2. I'm going to reinstall it once more then I'll give up and
move on to Red Hat. The only reason I'm installing it at all is because
the client wants it. Any and all advice will be vastly appreciated !
Best regards,

Hi all,
I asked this once a couple of years ago, but not only do I not remember the
answer (I think it may have been it's ok to post here but we should really
rename the list), but the answer may have changed since then.
For Linux MIDI topics (not audio, but MIDI), what would be the most
appropriate list to post on? For my purposes, I think alsa-user since ALSA is
what I use. Any thoughts? I take it that there is not a linux-midi-users
list!
