Low Latency vs. Real Time Kernel
by Brian Monroe 10 Nov '14

10 Nov '14

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 23 Aug '12

23 Aug '12

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 23 Aug '12

23 Aug '12

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 -- Jørn Lomax CS Student University of Tromsø

Theming for Fedora Jam
by Jørn Loamx 17 Aug '12

17 Aug '12

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.

amSynth-1.3.1
by Martin Tarenskeen 13 Aug '12

13 Aug '12

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: ---------8<---------------- diff -ur amSynth-1.3.1.orig/src/Config.cc amSynth-1.3.1/src/Config.cc --- amSynth-1.3.1.orig/src/Config.cc 2012-08-11 16:32:24.019592715 +0200 +++ amSynth-1.3.1/src/Config.cc 2012-08-11 16:37:15.608128292 +0200 @@ -8,6 +8,7 @@ #include <iostream> #include <cstdlib> #include <sstream> +#include <unistd.h> using namespace std; ---------8<----------------- 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? -- MT

Official test day 23.08
by Jørn Loamx 12 Aug '12

12 Aug '12

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, -- Jørn Lomax GSoC student Fedora Audio Spin CS student University of Tromsø
