Hi all,
Many thanks for your replies. Audacity and Traverso are certaintly
well-established projects, so I think I could learn a lot from them. I also
spoke previously (about a year ago now) with Remon from Traverso, who kindly
invited me to join so perhaps that could be an option too. I'm very keen to
learn about how audio software works so hopefully this will be the start of
my learning. Slightly off the topic...has anybody been having issues with
the new pulseaudio server in Ubuntu Intrepid? I tried one of the fixes
suggested on the forums (reverting to esound) but it still crashes
sometimes. It's annoying me now, the previous version was fine!
Thanks,
Daire

Hi!
This already went to the LAU list, please ignore if you are subscribed
there, too.
This is a call for contributions. Take your chance of becoming part of
a crowd of people all around the world, counting to the rhythm in
several languages!
Contributors will be credited in order of their submissions and this will
also likely influence the order of use in the track ;)
Besides recording yourself and family and friends and pets (if they are
able to count), you can help by spreading the word.
What I'm after are recordings of one person at a time, saying:
A: "One Two Three Four"
B: "One and Two and Three and Four and"
C: "Beat" (to be translated to whatever makes sense 4 times in one measure
at 4/4. A single utterance is enough, as I want to use these as accent.)
- Translated in a native language and any language spoken without much
of an accent. If there are special ways of counting to the beat in a
language, use those (only or even better additionally) and inform me.
- With a tempo of 110 beats per minute (to be very clear, the "and" has
to be between beats ;).
- A and B should ideally be recorded with about 4 iterations (4 measures)
Don't think that your language will already be well-represented without
you. Others might think the same ;) Also, the more I can layer in one
language, the better.
All files should be:
- ideally wavpacked, or plain WAV as second choice
- 32 bit float, 48 KHz
- Trimmed
- Normalized
- Dry
- Explicitly licensed as http://creativecommons.org/licenses/by-sa/2.0/
or released to the Public Domain
_Only_ if you don't record with a JACK application, 16 and 24 bit integer
formats are also acceptable.
Please name the files as follows:
- firstname_lastname_language_count.wav for "One Two Three Four"
- firstname_lastname_language_count_and.wav for "One and Two ..."
- firstname_lastname_language_beat.wav for "Beat"
Email attachments are no option for such large files, so only send
links to uploads. Consider using http://www.getdropbox.com/ if you have
no other space. Please mail me off-list for submissions and on-list for
questions.
I'm also available as thorwil in #lad and #ardour at irc.freenode.net.
My intention is to offer the result and the material on archive.org.
This is an open-source project ;)
I also want to submit a version to the
https://wiki.ubuntu.com/UbuntuFreeCultureShowcase
I can't promise to use all contributions. I will sort out ones that
sound suspiciously different from others claimed to be in the same
language ;)
However, all serious contributors will be given credit.
Deadline:
I will start to work with the material as soon as I have enough, but
will accept more until the 23rd of January.
Thanks!

Hi all,
My name is Daire O'Neill. I've just joined the list to hopefully begin my
learning on audio development and possibly to contribute to some current
projects. As a beginner, I have only basic C/C++ skills, and have never
worked on any major project before. I do have a good knowledge of audio
technology and some basic DSP concepts, its the programming side of things
that lets me down! I'm currently working my way through 'Accelerated C++' by
Koenig and Moo though, so I'm learning every day. I really want to learn
about audio development and become involved with an audio project,
particularly a multitrack recorder. I would like to be able to write my own
simple multitrack recorder eventually. Anyway, if anyone has any tips or
suggestions, or can recommend a project where I could be of help, then
please let me know.
Regards,
Daire
I tried to install Express Scribe, but it wouldn't install under Ubuntu.
It has the features I'd need.
The features I need in such a program is a way to "remotely" signal to
it to pause, rewind five seconds then unpause. A desired feature would
be some way to speed up and slow down the audio stream without altering
the pitch.
Do I need to program a transcription program for the Open Source world,
or is there one already?
I worked in the past on FreeBSD audio drivers, and have done some simple
audio applications under Linux, such as a text to morse-code generator.
I have a lot of transcribing to do, so writing such a program may be
worthwhile if it isn't already done yet.

Hi,
A couples months ago we started a forum at linuxmusicians.com . Our aim
is to bring Linux musicians together and help each other to make music
on the Linux platform. We want to promote FLOSS software for making
music. We also want to make making music on Linux more accessible for
newbies and less computer minded people. We think a forum is a good
platform for this.
For making music on Linux, we need of course good software. To
inspire and help people to become a Linux audio developer, we launched a
special part for developers on our forum, which you can find here:
http://linuxmusicians.com/viewforum.php?f=44
As mentioned before, this should be a good and accessible place for
newbie programmers. But we also like to invite more experienced
developers to share their stuff, knowledge and help some newbies with
their first steps. Would be cool if some of you guys will visit the
forum sometimes a month (for example) and give some feedback to newbie
programmers or projects. If someone like to write an article about how
to become a Linux audio programmer and how to start, you're very welcome!
We are aware of the fact that there is also a linux-audio-dev
mailinglist and IRC channel. We also think the Linux audio development
community should operate as centralized as possible. So people can learn
from each other and make a good interaction between different apps and
projects as good as possible. That's why we wrote a short introduction
in which we make new developers aware of the existence of these places.
http://linuxmusicians.com/viewtopic.php?f=44&t=780
We hope we can inspire young and talented people to become a Linux audio
developer. We hope that you guys will support this initiative and are
willing to help new developers find their ways in the world of Linux
audio development.
Kind regards,
\r
Hello All!
I am just starting to use JACK and trying to run some of the example
clients. I am able to hear audio from the metronome example by connecting
the metronome output to the system playback ports.
However, when I connect metronome output to the simple_client input, I do
not hear any audio output. Since the simple client copies data from the
output port to the input port, I notice that the it should work in the same
fashion. Would anyone have any suggestions as to what could be possibly
wrong?
I am using qjackctl to launch the jack server and view the connections
between the different readable clients and the connections seem to show up
fine.
Thanks for your help. Happy New Year!
Regards,
Gopal
