Would someone be kind enough to tell me how to connect the IEC 958 Type 1
balanced AES/EBU digital inputs and outputs of an Alesis MasterLink to a
Linux DAW with an RME soundcard (not yet purchased)?
Should I buy the HammerFall HDSP 9652 or one of the older cards for use with
Linux? Which extension cards or external interfaces should I be looking at?
I have a lot of Linux experience but very little digital audio experience.
Many thanks.
John Ouzts
Here is another good one.

Subject: [linux-audio-user] Which audio card to use?
Hay,
can someone tell me which audio card to choose or to point me to some
site where I can read about it.
I'd like to mix music. I.e. to build some kind of small home studio.
Thx
Regards
Janez

I am writing here because my problem involves many tools.
I have been trying to make extremely compact mp3's for download.
$lame PO_audio.wav -m m -b 8 PO_audio-low.mp3
LAME version 3.93 MMX (http://www.mp3dev.org/)
CPU features: i387, MMX (ASM used), SIMD
Autoconverting from stereo to mono. Setting encoding to mono mode.
Resampling: input 32 kHz output 8 kHz
Using polyphase lowpass filter, transition band: 2742 Hz - 2839 Hz
Encoding PO_audio_kino.wav.wav to PO_audio-low.mp3
Encoding as 8 kHz 8 kbps single-ch MPEG-2.5 Layer III (16x) qval=2
Frame | CPU time/estim | REAL time/estim | play/CPU | ETA
1038/1040 (100%)| 0:05/ 0:05| 0:05/ 0:05| 13.322x| 0:00
average: 8.0 kbps
Everything looks right except that when I play the resulting file in xmms or
mgp123 it plays much too fast.
Could the headers on the mp3 be wrong? how do I check? they show up correctly
in xmms and mpg123.
mpg123 PO_audio-low.mp3
( ... )
Playing MPEG stream from PO_audio-low.mp3 ...
MPEG 2.5 layer III, 16 kbit/s, 11025 Hz mono
I know I used to play lower than CD quality sample rates.
Does anyone have an idea what is going on?
I have tried differing combinations of ecasound and lame with combinations of
-sr and -rate switches, to often similar results.
I am using the alsa drives from cvs for my audiofile 2496,
Thanks,

1. A short summary of changes
Sliders for parameter control and text inputs for
lower and upper bounds have been added as well as
support for LADSPA-1.1 and ecasound effect parameter
hints. There has been some user interface improvements
and a native JACK support has been added. Updated to
use the new ecasound-2.2 libraries.
---
2. What is ecamegapedal?
Ecamegapedal is a real-time effect processor software with
a graphical user interface for controlling the effect
parameters. It is meant to be used as a virtual guitar-fx
or studio effect box. In addition to real-time operation,
ecamegapedal also supports reading from and writing to audio
files. All audio object and effect plugin types provided by the
ecasound libraries are supported. This includes ALSA, JACK,
OSS, aRts, over 20 file formats, over 30 effect types, LADSPA
plugins and multi-operator effect presets. Ecamegapedal's
implementation is based on ecasound and Qt libraries.
Ecamegapedal is licensed under the GPL.
---
3. Changes since the last stable release
* Added native JACK support. If compiled with JACK support
enabled, ecamegapedal will upon startup fetch the
current engine parameters from the JACK server, and
initialize the ecamegapedal configuration to work
with JACK. In practice this means that you don't
have to manually set the buffersize and sample rate
parameters to use ecamegapedal with JACK.
* Support for LADSPA-1.1 and ecasound effect parameter
hints.
* Text inputs for overriding default upper and lower
bounds for parameter values.
* Sliders for controlling parameter values.
* Pixmaps for transport control buttons.
* Takes advantage of the newly released ecasound 2.2.0
libraries (does not work with older ecasound releases).
* Should work with all released Qt2 and Qt3 versions.
Tested with qt-2.3.2, qt-3.0.5 and qt-3.1.1.

Audio software for Linux!
hi all
thanks for the advice patrick
actually im going to upgrade to cvs
will give it a go shortly and let you know the outcome
have to go the back route around doing it as KDE depends on the alsa
rpms.. i did a lovely job of killing X last night by messing with
those... so i'm going to simply tar up the modules and install cvs...
i presume a few spare extra alsa libs around the place shouldnt do any
harm... i hope!
thanx

I have compiled, installed and loaded the ALSA rme9652 driver. It's
compiled without OSS. Using arecord/aplay, I can only record and playback
files in mono format. Stereo is eluding me. Pardon the ascii art,
monospace font required. My configuration is:

Also, I can only arecord/aplay using the plug layer. All attempts to use
hw fail with:
aplay: set_params:781: Access type not available
The consumer card is card0 (cs46xx, Hercules Game Theater). My .asoundrc
is:
pcm.Crystal {

}
ctl.Crystal {

card 0
}
pcm.RME9652 {

card 1
}
ctl.RME9652 {

}
I used alsactl store/restore to enable the S/PDIF on the Hammerfall. It
works fine for mono recording and playback. The card is set to AutoSync
and I can see sample rate changes made on the ART converter picked up in
the Hammerfall.
Thanks for any help,
Phil
I've fixed some build issues and theoretically made it slightly more
efficient. If you managed to build 0.0.1 theres no real point in you
upgrading.
Theres also now a webpage of sorts, with a screenshot ;)

Greetings,
I always give my best effort before bothering anyone on this list. I
just can't find the missing peice.
Here's the situation:
I create sequence tracks in jazz. Then I record live tracks in
ecasound while the midi file plays via timidiy. The problem is that
jazz plays from the sound card and timidity can only play .pat files. I
create a lush sounding recording in jazz and when I play it with
timidity, it sounds weak. Appeartenly, ecasound only supports playing
midi files via timidiy. And timidiy can't access the sounds on the sound
card.
I've been looking all over for several solutions:
(1) A midi to wav converter that creates a wav that sounds like what I
created in jazz (via the sound card). Then I can just play the wav in
ecasound while I record my live tracks along with it. (Timidity will
covert to wav, but it's the .pat sounds). I tried using vsound, but it
fails with every midi player I've tried.
(2) I keep hearing about alsa "capturing" sound. I can't find any
documentation on what and how it "captures". Can I press play in a midi
player and the sound can be recorded to wav? If so, how?
(3) Is there a program that converts .sf2 to .pat. If so, then when I
play midi files with timidity, they will sound like what I created with
jazz.
Thanks in advance...
Rocco

Nice Article! How did you manage to get SOS to run a Linux article? I
was wondering if it would ever happen ;-)
Maybe one day there'll even be a "Linux notes" section at the back
alongside mac & pc. ah, i can dream :-)
