Low Latency vs. Real Time Kernel
by Brian Monroe
I've been spending a lot of time on the #opensourcemusicians channel
talking to Ubuntu Studio users about their kernel and latency times they're
getting. Seems like most of them are using g a stock kernel with the
preemptive option enabled and they are getting great latency results
(2ms)while utilizing the @audio group on their user. I ended up compiling
my own low latency kernel and I haven't had any issues with it yet. If this
is what we are missing for the spin I'd be happy to maintain packaging for
the kernel. I know ccrma has been behind a few kernel releases.
I saw the instructions for adding the real time patch for a tick less
kernel and from what I can tell it wouldn't be hard to get that rolling as
well.
I'm not entirely sure what ccrma does differently with their kernels
compared to other Linux users, and I'm still a bit of a noob so I could be
off base with this, but I would reason that we should be able to just
utilize the same settings to archive similar performance enhancements.
I thought I read that ccrma uses a unique scheduler, but if we could get a
2ms latency time without it, the point may be moot.

Congratulations in order
by Brendan Jones
Hi all,
this is just a quick memo to congratulate Jørn on his completion of the
Fedora Audio spin project.
I've been really impressed with his communication skills, his confidence
and his new found love for Fedora (there is some security in this
bureaucratic madness). He has been an absolute pleasure to work with and
has shown great diligence towards the task at hand. I'd also like to
thank the co-mentor Chris for his efforts and past experience.
I've really enjoyed being a mentor this year - it has got me thinking
about next year already. Now that we have the spin under our belt, I'm
looking for new ideas/tasks that we can achieve (GSOC or not). Some that
have come to mind:
- a dedicated Fedora Audio design team (ie. providing wallpapers,
desktop themes for all DM's)
- improving pavucontrol or providing a better "jack-aware" one
- upstream tasks such as jack, qjackctl and pulseaudio. I don't expect
Rui to ever sanction the idea that qjackctl ever acknowledges pulse but
its an idea)
- making Jørn's audio control app a formidable player in all desktops
Anyway - food for thought. Please use this thread for further ideas as
to how we can make Fedora audio better.
Brendan
PS. I'm thinking of adding an Audio tag to the groups file. IE.
yum groupinstall Audio
Lets start the list of packages now?

Test day 23.08 postponed
by Jørn Loamx
I'm sorry to inform that the test day the 23.08 will have to be
cancelled/postponed.The fedora spins are still not composing against
f18/rawhide, and there is not much point to do a big test day against
f17. We will find a new date when the spin will compose cleanly against f18
I would also like to say that this is my last message as part of GSoC.
That's not to say I won't be around any more, but I won't be in my
office from dawn til dusk staring bewildering at packages.
I would like to thank everyone for their help and making me feel
welcome. I have worked on several projects before, but none has been as
welcoming as working with fedora.
Hope I have been able to help the fedora music community this summer,
and I hope to see you all around

Theming for Fedora Jam
by Jørn Loamx
Now that most of the technicalities and packages of the spin are in
place, we should start looking at theming and usability. I have no
knowledge of KDE and what people like, so this is where we need help.
On the git repository we know have a theme package[1]. Play around with
this and see what you like. To try it out, copy the directory, make
changes to the file run make && make install. Then you can see what your
theme looks like. We also need to know if we should add an extra panel
to KDE, what apps we should have easy access too etc.
We want as much feedback as possible so that we can find out what works
best for most people.

Morning all
We are having the last meeting where I'm part of GSoC tomorrow(Mon,

update about the current status for the spin. We will also discuss the
upcoming test day.
Sorry for the late reminder, but I hope as many as possible can show up

amSynth-1.3.1
by Martin Tarenskeen
Hi Nick,
I have downloaded the sources for amSynth-1.3.1, succesfully compiled, and
running on my Fedora 17 system. I especially like the fact that I can run
it both as standalone and dssi-plugin, including the new GUI.
I only needed to apply one little patch to compile succesfully:

In other words: I had to specifically "#include <unistd.h>" in Config.cc
I think newest gcc versions are more strict in that, but I guess it
doesn't hurt to add that line also for older/other compilers?

Official test day 23.08
by Jørn Loamx
I know it has been quiet on the list as of late. a quick update on the
status of the project:
Everything is good to go, we are just waiting for the o.k from the spins
team. We are also waiting for fedora rawhide to branch, as the spin is
not composing against rawhide (no spins are composing atm.), which
explains the slow approval process
But the biggest news is that we have a date for the first officials test
day. Mark down 23.08 in your calendars! Tell your friends, neighbours,
dogs, cats, blogg readers. The more people we can get to join in on the
test day, the better. By then we will definitely be building against
fedora 18 so there will be plenty off things to try out.
regards,
