Hi List,
for a project at work (nothing to do with music, sadly, but at least audio)
I'm looking for an audio interface that supports at least 16bit/48kHz
(24bit/96kHz would be even better, we're potentially looking for rather
high frequency signals...) for two mics that need phantom power and where
the preamp gain can be controlled remotely by software, as this will be
used as follows:
The whole setup will be mounted at a remote location inside a larger
machinery for audio surveillance of said machinery (fault detection etc.).
The larger machinery of course may not be running while opened to install
our setup, thus setting the gain has to be done remotely.
The PC in this setup has an x86_64 CPU running Ubuntu 12.04 LTS, but the
case is too small for PCI(e) solutions, doesn't have firewire, so the only
option is USB.
For our current setup we have a Focusrite Scarlett 2i2 here, but there's no
way to set the mic gain via software :-/
Researching so far led me to the RME Babyface that is said to be supported
when in class compliant mode - but you seem to need to hold down buttons
while turning it on, which is a problem as we can't open up the larger
machinery every time the hardware needs to be restarted.
Is anyone here aware of something we could use here?
Thanks in advance,
Thomas
Hello list,
I have moved the LA social and community guide from my personal website
to the linux audio wiki and merged it with the stub article there.
http://wiki.linuxaudio.org/wiki/places1
I have also added the two Germany-based LA meetings to the wiki.
If you know more places online and offline, especially offline, where
open source music people can meet please update the article accordingly.
Greetings,
Nils
Hi Larry,
i actually thought most mp3 editors worked as you described...but I do
not normally edit mp3 files or not this way.
does not audacity have a command line component to it?
Cheers,
karen

OK, a continuing thank you for ideas in my quest to edit mp3s. I received this
back from an author of dae:
I will put it up at ftp.meraka.csir.co.za/pub/in/wvdwalt/dae-latest.tar.bz2 for
now.
The mirror I used for it lately is down because of hardware problems.
It cannot edit mp3 yet, and probably never will.
The library used in dae is ecasound which do not allow editing of mp3.
Therefore, you need to first convert the mp3 to wav, edit it, and then convert
it back to mp3.
Although that can be automated using sox or such, it is not a good idea, as the
quality of the audio will degrade every time
you edit the file.
Back again live, as I said his program is a good example of the type of a
concept. Thanks so much in advance

i'll second the Akai MPK-88, being a piano player, also. It can send and
receive at least two streams of MIDI over 16 channels. i've had it for a
few years and it's been sturdy, though i can't say i practice like i did in
college. The pads are excellent for any live drums you might want to play
as well as system control changes to any synths you've connected to it.
The sliders are beautiful if you've a virtual B3, and the knobs are
continuous, so you can twist away without breaking them. It's USB
powered. And best of all: i plugged it into my computer and it worked
right away without downloading a single driver.
You're in Toronto? If you ever run into Borys Medicky, tell him, "Hello,"
for me.

Hi All,
I am still appreciating all the sound card wisdom! I think I shared I am
aiming for the m-audio audiofile 2496, which I am finding on ebay.
I visited our hackers lab here in Toronto hoping to find someone with
enough Linux debian smarts to help me here with the software part of my
circumstance.
As there are apparently many ways I can ahem play the composing side of
things with all the command line tools, I am wondering if folks have
keyboard or workstation suggestions?
I will likely need to be more specific, but do not want to stop the flow of
ideas.
Thanks,
Karen
Hello,
Seeing the description in Ardour's manual for mixed MIDI/Audio tracks
and how they relate to Reaktor, which I knew nothing about, I looked
into it and found an Ubuntu page on how to run Reaktor using
basically wine and dssi-vst. So I got the sources for dssi-vst and try
to compile on a 64-bit machine. Got the Steinberg SDK, the multilib
for g++ and gcc, made a symlink for zconf.h to be found and now the
compile halts at not finding '-lz'. I tried installing libzip, then
lzip (lzma compression) but none are fulfilling the requirement.
What is this -lz exactly ? And, anyone running Reaktor in this way ?
Thanks.
Hello,
Using wine 1:1.6.2-0ubuntu4 I could install the Reaktor Player. By
following this install procedure:
http://whiteelephantaudio.com/installing-reaktor-linuxubuntu/
System is Linux Mint 17, 64-bit. dssi-vst is 0.9.2-1ubuntu5.
One thing to notice is that the 64-bit version of Reaktor is not
recognized at all by the system/wine. I then did as the web page
instructs and copied the 32-bit version which works.
Reaktor is seen in qjackctl and it is possible to connect a MIDI
keyboard to it and hear stuff. I understand that all instruments
provided with it are free. I also installed the mikroprism
instrument. Now, all these are running in 30 minutes max time slices.
So I chose to register the free mikroprism. It then launched some app
called 'service center' and ended up with an error and a binary log
file.
Has anyone got past this 'service center' problem ?
Cheers.

Hi,
I wonder how many people use jack-rack.
Now and then I use jack-rack. IMO it's useful.
It's still provided by the AUR:
[weremouse@moonstudio ~]$ sudo systemd-nspawn -qD /mnt/archlinux/
[root@archlinux ~]# packages jack-rack
Repositories
aur/jack-rack 1.4.7-4 (78)
Effects rack for JACK
Installed
local/jack-rack-git 20130328-2
Effects rack for JACK
It's seemingly not under development:
http://sourceforge.net/projects/jack-rack/
At the Ubuntu Studio devel list is a discussion that leads to two
questions.
1. How much is jack-rack used? Especially how much is it used by Ubuntu
users.
2. Is there a replacement for jack-rack?
The reason for this questions is, that it's dropped by Debian and it's
interesting to know, if maintaining an Ubuntu package makes sense.
Regards,
Ralf
