hi everyone:
i'm running on a PIII with kernel 2.4.18 and Alsa 0.9.0rc6 and a Hammerfall 9636 card.
Alsa has been working fine for the last year, or so it seems. recently a scsi CD burner
was installed. i have some recordings of live performances made with "arecord", version
0.9.0beta8a. they play back just fine, but when i tried to burn them to CD, they were low
by about 2 to 3 half steps.
Joerg Shilling suggested that Alsa was writing the wrong headers. so i upgraded to rc6
and on the first try on each of the old WAV files, "aplay" also played them too slowly.
however, on subsequent runs, everything was fine again. i don't understand this behaviour
at all.
someone on LAU suggested that since it was too low by about 2-3 half steps, data was being
recorded at 48000 but Alsa thought it was at 44100.
info in /proc/asound/hammerfall/rme9652:
------------snip-------------
.
.
Latency: 4096 samples (2 periods of 16384 bytes)
Hardware pointer (frames): 0
Passthru: no
Clock mode: autosync
Pref. sync source: ADAT1
IEC958 input: Coaxial
IEC958 output: Coaxial only
IEC958 quality: Consumer
IEC958 emphasis: off
IEC958 Dolby: off
IEC958 sample rate: error flag set
ADAT Sample rate: 44100Hz
.
.
---------snip-----------------
for months up until about an hour ago the ADAT sample rate read 48000. in that hour i
changed my .asoundrc from
-----------snip---------------
pcm.hammerfall { #"hammerfall" is the alias for "snd-rme9652" in /etc/modules.conf
type hw
card0
}
ctl.hammerfall {
type hw
card0
}
-----------snip---------------
to the following
-----------snip---------------
pcm.rme9652 { #changed from "hammerfall" to "rme9652" on 12.15.2002
type hw
card 0
}
ctl.rme9652 { #same as above comment
type hw
card 0
}
---------snip-----------------
after the .asoundrc change i recorded a fresh WAV and burned it to CD but with the same
problem -- too slow. also, with the new .asoundrc, version rc6 plays WAV's recorded with
the old .asoundrc and version rc6 a little too fast. i'm at a loss for new ideas to debug
this.
can anyone enlighten me about this, or does anyone know where i can download some
reference WAV files (for example, a middle C tone) to check whether the burning problem
might involve Alsa or whether it's something else in my setup?
any pointers would be greatly appreciated.
tia,

There was some talk of silent cooling earlier in the week. It reminded
that i need to quiet my new pentium 4 box. Does anyone have any
experience with Zalman? In particular, this:

Seems they have "silent" power supplies... Comments?

We are pleased to announce Quicktoot release number 10
http://www.djcj.org/LAU/quicktoots/
----------------------------------
A first approach using Protux - Protux tootorial
Written by Reinhard Amersberger.
Protux-0.14.0 works in a different paradigm. Protux will allow you to
utilize the power of keyboard+mouse combination (with no clicks)
"Jog-Mouse-Board" or JMB, for short, to vastly speed up the process of
audio production.
You can use it for a simple Multi Track Project but development from
Mustux, the Musician Tools Paradigm Projects, multicultural team is
rapid so expect enhancements.
-----------------------------------
The purpose of the Quicktoots are to provide a community resource of
informative guides for using Linux audio applications.
The Quicktoots are the brainchild of Dave Phillips the man responsible
for the most comprehensive webpage devoted to Linux audio applications.
The Linux Sound and Midi page. Your one stop resource for Linux sound
software.

If you are in the position to link to any of the quicktoots please link
to the main page. That way we can keep more accurate statistics on the
amount of people viewing the pages.
If you are interested in contributing to the Quicktoots please let us
know. All work must be submitted to either Dave or myself and we will
give advice or make changes to ensure our publishing standard is met. If
you are not in a position to format any contributions don't worry
because I am willing to format any braindumps.
Enjoy.

"Um...symbol_get and symbol_put... They're
kindof like does anyone remember like get_symbol
and put_symbol I think we used to have..."
- Rusty Russell in his talk on the module subsystem
from the documentation of abcmidi, i would think this would play a Dm7:
X:1
T: testing
M:4/4
L:1/4
Q:1/4=40
K:C
"Dm7"
but instead it gives absolute silence, and reports no errors. do i need
to do anything special to enable guitar chords with abcmidi?
at the very least, is there an alias scheme that i can use so i don't
have to type [DFac] everytime i want a Dm7?

Changes
* Greatly improved the readability of the VU meter
* Made the VU meter conform the the AES analogue equivalent levels. This
should make it more generally useful without adjustment and if you
have properly calibrated DA converters and analogue equipment then
the levels should agree.
* Made the DPM meter look nicer and easier to read.
* Cured a handful of segfaults (thanks to Melanie and Mark K.).
* Reduced the maximum CPU usage of the UI. It should never have caused RT
problems before, but it could have stolen cycles from other UI
threads that needed them more.
* Cleaned up and optimised the port insertion (input monitoring) code, its
still hacky but cleaner and more reliable now.
* Added a "set jack name" option, -n.
* Will now make a meter for every non-flag argument, even if there is no port
matching that name, so, eg. you can create an unconnected 4
channel meter with "meterbridge - - - -".
* More reliable cleanup on exit.
Before it goes to 1.0 I'd like some sort of documentation, and maybe to
improve the input port monitoring situation. So don't hold your breath ;)
If anyone wants to write anything for the docs I would be extremely
greatful.
I will look at any tricky things, like meter labelling, and antialiased
needles after 1.0.

Hello everyone.
I would like to make a small home studio. I haven't played in about 5
years, so I am a little rusty, and not "in" with the times. I was looking
on-line for open source mutitracking software. I came across ecasound and
ardour. Ecasound looks a little more difficult to use, so I will probably
start with ardour. Before I get started, however, I need know a few things,
as purchasing new hardware will be a must for me. I was hoping some of you
could give me some advice, or let me know what your set up is.
Vexing questions:
1) How important is a da-ad converter, and how much must one spend on this?
2) What does one look for in a soundcard. Is it necessary to invest $600
in one -- I mean, where is all that money really going? What makes a card
like the hammerfall so great? How much on these cards is "fluff" and how
much is really practical for just recording.
3) Do people actually use fiber for their lines? Or is this super-duper
high end stuff?
4) I have spent some time on some sites of card manufacturers... and I
can't quite piece together how multiple inputs work on the cards... is it a
one for one deal (one input = one channel), or is their some software or
hardware that allows for more than one channel per input?
5) how good is open-source software for effects processing... I saw
something on the ardour site saying that it does not support "plugins"...
(due to lack of a standard)... does that mean no effects?
6) What do you guys do for a drum machine solution, is software adequate or
do you really recommend getting a drum machine?
7) Does everybody go direct on this, or do they mic their amps (I am
primarily a guitar player). How do you keep the sound quality up if you
are direct?
8) I want to build a **QUIET** machine... Any suggestions on computer
hardware? (I have bought from quietpc, and found that some of the stuff
was no quieter than normal --even louder some times).
I am sorry to hit everyone at once with these questions (and I have more,
belive me), but I can't find a good place on line or otherwise to give me
the low-down on what it is needed. I would love to hear the setup others
have and the plusses and minuses regarding them.
I am accustomed to using cassette tape 4 tracks, and analog mixers and I am
pretty familiar with linux and open source stuff (although I am not
primarily a coder).
I have a marshall jmp-1 preamp with a valvestate 8008, a RockTron
intellifex, proq and guitar silencer (all rackmount) on top of a marshall
jcm-900 lead-1960. I would be sad to see some of it go, but since I am not
performing, I would be willing sell some off if there is better stuff for
home recording. I would only need about 4 simultaneous inputs.
Excluding the pc I must build, I would like to try to keep the price around
$1000 (including the sound card). Is this realistic? I might spend more
if I wind up selling some of my current equipment.
I would appreciate any advice here.
Thank you in advance!
Chris
hello friends,
i have successfully built timidity (2.12.0), then jack (0.34.0), and
finally muse --with-jack (0.6.0pre5).
timidity works by itself, i can play midi files and it sounds. my intention
is to use it as a software synthesizer for muse, so i launch it with the
option -iA.
but muse also requires jack to be running, so first i invoke jack like
this:
jackd -R -d alsa -d hw:0
and then i can run muse. the problem is that as soon as i have jack running
timidity doesn't sound.
all right, the real problem is that i never got to fully understand jack,
so i have no idea how it works or how i can make things work together. as
soon as i begin more confused than before so i give up.
any charitable soul could give me a quick hint on how i should invoke
timidity and/or jack so that i can use the combination of the two as a
software midi device for muse? (i used to use it like this in the past, but
that was without jack coming into play)
thanks for any help.
best,
lj
hi all,
i know that music theory is off-topic for this list.
generally, how tolerated are off-topics posts on this list? i've been
experimenting with some new theory i've learned and wanted to know why
something sounds terrible.
if this list wants to be totally on-topic (which is understandable), can
someone recommend a flame-free mailing list for people who want to ask
questions about jazz theory?
my teacher doesn't have an email address, and i'd like to get an answer
before my next lesson. :)
sorry for asking, but i'm very new to this list and don't know the group
dynamic yet.

Hi,
If anyone is using this card and actually has tried to get MIDI
working, could you please drop me a note and let me know if your results
were positive or negative?
I've been messing with this for a few days and it's just not
happening for me.
Thanks,
Mark
