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.

Hi, is there any interest in the Audio SIG for taking this package on?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Congratulations to Jorn Lomax, who was accepted to Google Summer of Code 2012 for the Fedora Audio Spin! This is good news for all of us here in the Audio SIG, and I hope we can all find the time to lend a hand where possible. A list of accepted proposals can be found here: https://www.google-melange.com/gsoc/projects/list/google/gsoc2012 Fedora has 10, and they all look interesting and useful. Thank you to all the students who applied. I hope everybody finds a way to contribute in the future.

Action items for the Audio spin
by Brendan Jones 19 May '12

19 May '12

Hi all, there's been talk of a road map for the Audio spin and I'd just like to jot down some suggestions for what we might like to achieve. - installation media requirements. I'm proposing a smaller Live CD (lite) and a full blown DVD installer. - default Desktop for both installations. I would like something with a really small size/footprint for the Live CD. Perhaps we can try LXDE for the smaller and KDE for the DVD? - default set of packages for both - revisit multimedia-menus package and determine which packages need additional Categories in the desktop file - how best to package the Musicians guide - how to achieve optimal RT performance from the stock kernel (adding threadirqs to the kernel command, assigning jackuser/pulse-rt group membership) - default pulse/jack setup with pulse->jack bridging 'out-of-the-box' - determine what packages from CCRMA and RPMFusion are must haves in the Fedora repos and can be rebuilt to comply with Fedora licensing. - desktop style and icons on install- darker themes are an obvious choice for audio (often poor lighting etc) but can be a pain for normal use. There are ways around this (Arch linux has some good tips for achieving this - perhaps we just need to document it somewhere) - and of course updating the Wikis Most of this stuff is pretty trivial (but possibly time consuming). Achieving the perfect setup out of the box w.r.t. RT performance, jack and pulseaudio is going to require a lot more thought and possible *real* development. As I've said before KXStudio has tried to solve this problem with its cadence app (still pre-alpha). It makes a few assumptions about applications (presence of ladish for example) which may not necessarily apply here, but we can certainly learn a lot from their work. I'm thinking that some of this could be assigned to the successful GSoC candidate. As I said I'm really just listing these as suggestions - and to try and promote some more discussion (please!). I'd like to document this somewhere on the wiki as well. Please let me know if I've missed anything or if you have strong objections to what I've suggested. I'd also like to round up all interested parties for an IRC meeting for a round table of sorts (and to determine who is actually committed to making this work). regards, Brendan

Multimedia menus in Gnome3
by Brendan Jones 18 Apr '12

18 Apr '12

Hi all, I've recently noticed that the multimedia menus package doesn't translate to Gnome3. Not sure if there's a way around this but I thought I'd make a note of it here. As the idea of submenus doesn't seem to exist in the Applications screen, I wonder if there is another way or if it is even required under this paradigm. regards, Brendan

Content Packaging
by Brian Monroe 16 Apr '12

16 Apr '12

I've had conversations with others about packaging content material for the Audio spin and it doesn't seem like that currently possible with how things are packed in Fedora. I know we don't quite have our package list together at this point, but I think there's a need for decent content for some of the plugins like samplers, reverbs, drumloops and the like. I think the more stuff like this we have available immediately for the audio spin, the more end users we're going to attract. Even presets for things like graphic EQs and the like. Anything to make less hassle for users... Anyone else feel this way, or am I alone in my line of thought? I may be easily persuaded after seeing it from another's point of view and I wonder how important it is in the large scheme of things. On a side note, I have sourceforge project that we could host content at if needed. (hurray for unlimited bandwith and drive space for large files) I know we're a ways off in implementing something like this, but it's not too soon to start gathering resources for it.

Adding entries of packages to the ofiicial Musicians guide.
by Vishnu M 15 Apr '12

15 Apr '12

After going through the music digest volumes I believe that some of the packages might not make it to the official repository due to Fedora Packaging Guidelines and some of them might be really good. I do not know if there is a provision for providing additional details in Fedora Musicians guide for those packages that does not make it to the official repository. If there is a possibility, then for those packages we can make entries to the musicians guide which will provide additional resources and methodologies to build and run those packages on their system which will inturn reduce there hassles. Again, we can provide details about the script(or its DE frontend) and its consequences in the musicians guide if it allows.

Adding a non-package to the wishlist
by Vishnu M 11 Apr '12

11 Apr '12

I just looked at the wishlist and did not find non-sequencer there so I think it must also be added . The wishlist link : http://fedoraproject.org/wiki/Audio_Creation I also think that packages in this link(http://non.tuxfamily.org/) must be added to the audio creation spin list. At least they can be added to the DVD version . https://fedoraproject.org/wiki/Audio_creation_spin_development#Primary_Pack…

Fedora Audio Spin
by Feroze Naina 09 Apr '12

09 Apr '12

Hey! I'm Feroze and I'm doing my undergrad in Engineering. I love recording and "mixing" my own music and have helped with my school skits and theatre. Most of my audio production work was done on Windows. I have a lot of experience with Linux development and would like to create Fedora Audio Spin. I am attracted to Fedora for its values regarding free software. I have been wanting an audio production environment with truly free and un-patented software. I want to make the Audio Spin very simple and intuitive for users with no prior Linux experience. My project proposal - https://fedoraproject.org/w/index.php?title=GSOC_2012/Student_Application_f… I'd like the Live CD to focus on production and editing. I've gone through https://fedoraproject.org/wiki/Audio_creation_spin_development#Primary_Pack…. I would love to hear your feedback as we need to shortlist the packages to be included. Feroze Naina
