Just starting to build my Linux audio studio, and having lots of fun so
far. Installed Jack, qjackctl, ardour, rosegarden, and bought the Edirol
FA-101, all working "out of the box". Pretty amazing.
Now what I'd like is an iPod player that's Jack aware. When I plug my iPod
into USB, Rythmbox understands the format and plays the media on it, but of
course, it won't play into my FA-101 'cuz it appears to have no support for
Jack. Anyone have a recommendation for an iPod player that's Jack aware for
Ubuntu 8.04?
Second question:
Any recommendations for an initial set of plugins for the basics in Ardour,
like Reverb, Chorus, etc.
Many thanks,
Chris

Hi,
With the recent discussion on low latency kernels which ones are people
using now?
Which versions have people had the most reliable results for audio?
Cheers.

Well as you all can tell from the recent posts, I'm trying to play
catch-up on everything I've missed in the Linux audio world. ;)
My problem tonight is with a2jmidid. (Note: I am *not* running an RT
kernel just yet. Don't know if this has anything to do with
anything.)
I start jack w/ qjackctl and attempt to run a2jmidid. This is my output:
JACK MIDI <-> ALSA sequencer MIDI bridge, version 4 (128) built on Wed

Press ctrl-c to stop the bridge
To be frank, I don't have the first clue as to what is going on here.
Can anyone give me some troubleshooting tips to help solve the
problem?
Debian Lenny, jackd version 1.109.2
I'm sure there's a lot of information I should be providing here, but
again, I have no idea what I'm doing, so feel free to beat me over the
head with a jack midi port. ;)

Evening Guys!
Does someone have gtalk and would be willing to test it with me? I just
signed into google-mail, which should give me access to it and I tried to set
up my asterisk to support it. But I'm still not sure, that it works, so I need
a "guinea pig". :-)
Thanks and sorry for the "guinea pig" business. :-)
Kindest regards
Julien

Hey Linuxaudio.org'ers,
It's been a while, and we're behind several announcements..
First of all: linuxaudio.org is doing fine.
Second I'll briefly mention a statement of our Director:
Ivica Ico Bukvic wrote : "We need to start thinking about the function
of the management board. This aspect has been all but dead. How about we
announce restructuring of the board and go from there? My suggestion is
to retain the core of those of us who are most active and then add key
figures in the community who will be active contributors to our cause."
No surprise there. Further discussion may or may not follow on
http://lists.linuxaudio.org/listinfo/consortium/ - and last but not least:
Holger Ballweg has stepped forward and done an amazing job updating
http://apps.linuxaudio.org/. We went on to http://wiki.linuxaudio.org/
which is finally due an official announcement:
* http://wiki.linuxaudio.org
open to public (openID/CAPTCHA)
Everybody is welcome to use this wiki for gnu/Linux and FLOSS audio
related projects or communication. Feel free to ask for additional
permissions or plugins. - send your project application or suggestions
to LAD, start writing a wiki page about it or send a patch ;)
We would like to support maintained and moderated namespaces adopted by
members of the community; balancing http://linuxaudio.org/members in
favor of interest groups. We have neither intentions nor budget to take
on wiki.ubuntu.com or wikipedia. Commercial interest is tolerated.
Professional interest in linux-audio is more or less a prerequisite. The
usual exceptions apply for Music, Art, etc. see http://linuxaudio.org/policy
..and we're not going to stop there.
Here's a quick overview of HTTP services, vhosts and tasks. Any comments
and suggestions are appreciated; as is help getting there:
* http://lad.linuxaudio.org - will be consolidated into drupal
(www.linuxaudio.org) and wiki.linuxaudio.org. - Apart from the
http://lad.linuxaudio.org/events/ (lots of pictures and media) there's
only 16 HTML pages. - similarly lowlatency.linuxaudio.org should become
an entry-point to the wiki.
* http://lad.linuxaudio.org/events/ should be merged with
http://lac.linuxaudio.org
* http://portal.linuxaudio.org, http://linuxaudio.org,
http://lac.linuxaudio.org/
Drupal CMS is edited and maintained by the consortium.
We're urgently looking for 2-5 Content Maintainers (and Guitarists) so
that some of us can take a holiday break.
Besides in the longer term we're looking for volunteers to summarize or
comment on a LAD/LAU thread once in a while, and editors to write short
articles in the likes of kerneltrap.org.
* http://wiki.linuxaudio.org/ is actually the same as
http://apps.linuxaudio.org/wiki/ - vhosts will be merged, redirect..
linuxaudio.org is going to stick to /international english/ for wiki
pages - We'll gladly link to non-english LAO sites - If you're in need
we can provide hosting or bandwidth/mirroring solutions for these.
* http://apps.linuxaudio.org/wiki/request
bookmarklet in beta test. Easy way to submit new apps.
* http://lau.linuxaudio.org and http://quicktoots.linuxaudio.org/
probably remain as is. There are a lot of hidden resources there! -
Maybe some minor updates on the front-page. point to the wiki or portal.
* http://ladspavst.linuxaudio.org/ - great as it is.
* http://ccmixter.linuxaudio.org - for a short time.around
http://www.linuxaudio.org/mailarchive/lau/2007/11/15 we set up a
bare-bone ccmixter.org intended for Music-Made-With-Linux. Should you
desire to style and maintain a ccmixter community: here's your chance.
* http://radio.linuxaudio.org/
Anyone interested? shall we stream random songs from lam.fugal.net ?!
repeat talks from the LAC? or better no-stream than some weird random mix?
* for http://forum.linuxaudio.org/ we started collaboration with
http://linuxmusicians.com/
If you don't like the current style/template: We're challenging
web-designers to come up with a better one.
The consortium-site is a http://drupal.org ; apps & wiki a
http://dokuwiki.org CMS. - get in contact with us on the LAD mailing list.
thanks for your attention,
robin for the linuxaudio.org team.

Is an m-audio sufficient for my use? Well, you decide.
My use is for speech recognition. I need the best input sound available, with the lowest latency.
Both are tremendously important for speech recognition accuracy. (Low latency helps with accuracy as well as speed.)
I run Dragon NaturallySpeaking through Wine. Wine does not play well with Pulse, so I disable Pulse.
I also need portable hardware that will work with a laptop. Mine is an ASUS. The built-in card is an hda-intel, so I must use something else.
Eventually, I want to tweak my computer for the lowest latency possible, and get the best portable USB device, but right now I'm content just to update my Intrepid real-time, and get a decent USB soundcard.

Hi. I've got hda-intel, too. Hate it.
I use linux audio to run Dragon NaturallySpeaking using wine. Sound quality and latency both hugely important to speech recognition, which is why I'm on this list.
Anyone have any luck with an m-audio transit?

Hi,
I've just published a free software that can recognize notes recorded by an
audio input device in real time.
It's here : http://davidferaoun.free.fr/eric/zik/voice2midi.php
This may interest users (it's can be used freely) and developers if they
want to put it into a bigger audio program.
There are 2 releases : signed applet and stand-alone. Both work on my PC,
but sometimes it seems that the signed applet may cause a browser crash.
The source code (in java) is available for download.
( Btw: I use a java FFT library from the online book
http://www.cs.princeton.edu/introcs/97data/FFT.java.html but I don't know
its license. Sorry )
Best regards,
Eric
I've got an intel-hda in my dell m90 that i've run hardy with its rt kernel
for months at 5 ms. I think what your missing is this configuration option.
/etc/modprobe.d/sound
options snd-hda-intel model=ref position_fix=1 enable=1 index=0
I found a blog post on it when I was trying to get my card working months
ago at:
http://linux-audio-music.blogspot.com/2008/05/improved-realtime-audio-with-…
good luck getting everything working.
