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.

Another GSoC 2013 Idea
by Christopher Antila 24 Feb '13

24 Feb '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi everybody! Maybe we could propose multiple ideas for GSoC this year. (Speaking of which, we'd better get started with posting our Ideas!) https://fedoraproject.org/wiki/Summer_coding_ideas_for_2013 Here's an Idea that I'm willing to mentor, even though I previously said I wouldn't: we sponsor an electronic musician to prepare a series of musical works, using only software available in Fedora (including PlanetCCRMA), and to document their process. This would be a huge benefit for us, for a number of reasons. First, we'd have more tangible demonstrations of the viability of creativity with FOSS software. Second, we could require different software (e.g., PureData, SuperCollider, Csound) for a broad demonstration. Third, we'd have more extensive documentation on "how to use computers to be musically creative," that would hopefully inspire both "unmusical" people and people who are "bad with computers." Fourth, we'd demonstrate that "coding" doesn't mean "use JavaScript to write a mobile app then profit lawlz" as "the media" seems to think, and to demonstrate that Fedora isn't only the upstream to Red Hat Enterprise Linux. Finally, and most importantly, we could use this as the basis to create a musical community around Fedora. When I first got here in 2010, what we needed most was a greater number of dedicated and active volunteers. That's still true now, but we're much better off than we used to be. In 2013, we have our own spin, we have our own documentation, and I suggest that the only thing we're still missing is the vibrant musical community. Whereas I used to believe that providing "the right tools" would create an active community, now I realize it's much more complicated. Active communities reproduce themselves. More specifically, the power relations of active communities tend to reproduce the communities in which they were formed. What we need to do is create the relations for the community we want, even though it doesn't already exist. It's a complicated way to say "cool music attracts people that will make cool music." Consider that, on this music mailing list, we should be discussing music and related issues, but we only discuss related issues (and D-flat). I really don't know what musical things people here do, and you have no idea what I do. I believe this is where we need to focus our efforts now. If we can use GSoC to basically commission a composer, and if a few more of us commit to producing at least one musical thing this summer, and if we do a good job of circulating our music through the right channels, I think we can kick-start the community we (or at least I) have been hoping for! Any thoughts?

For the Musicians' Guide, it generally goes like this: 1.) Have an idea and decide how to write it. 2.) Write a text-only draft of the idea. 3.) Put DocBook XML tags in where appropriate. 4.) Copy-and-paste into the appropriate section. 5.) Send the document for translation. 6.) Use Publican to generate the various output formats. Fedora documentation is usually published in four formats: HTML, HTML (single page), PDF, EPUB. Publican supports other formats. One result of this is that the same DocBook source code is used to generate all the formats, so we are advised against things that are only effective in one format. An example of such a thing is that we write out the whole URL rather than "click here," because somebody printing a PDF obviously can't click on paper--they would need to type the whole URL. For documents that interest Red Hat, there's a more complicated process involving paid writers, editors, and translators. > > Also, I just noticed that---although I published it and it is technically > > available---the Fedora 18 Musicians' Guide isn't properly listed in the > > menu on Fedora's Documentation website.

I think any packaging attempt is going to end badly because of our limited resources, and the reality that well-maintained packages require periodic, dedicated maintenance. Not to mention our "cross-distro" aspirations. But there's a better way. We could develop a web application that dynamically adjusts for distribution choice and integrates multimedia content. We could host it on Red Hat OpenShift. We could have the student develop an extension/module/something for Publican that would generate this web app automatically from pre-existing DocBook XML files. Obviously, this wouldn't be able to launch applications on a desktop computer (yet). But there are several important advantages: - - developing for Publican is a significant coding project, - - all DocBook-format documentation could be built into a web app, - - it's cross-distribution, - - it doesn't involve packaging (although Publican does already output RPM packages of documentation).

I'm obviously supportive of any attempt to improve documentation of free software, but we have to keep in mind that this is Google Summer of Code, and they only want "code"-centred projects. When I wrote the Musicians' Guide, it was part of Fedora Summer Coding, in a year when Google wasn't involved.

GSOC announced
by Brendan Jones 13 Feb '13

13 Feb '13

Hey all, GSOC has been announced for this year. If you have any ideas for the audio SIG, add them to the ideas page [1]. We lumped Jorn with a lot of ill-defined stuff to complete last year, and yet we still ended up with a nightly audio distro, which is a first. One project that comes to mind is finishing off Jorn's fedora-jam app, but we can only do this if we define exactly what it is supposed to do. Another I was thinking about was a documentation project albeit outside of Fedora. More of a Linux Audio user manual, based on what Chris has done, but packaged as a distro-agnostic project in its' own right (i.e. with examples, samples, project files etc). Something that can be packaged for use across all distributions? (the coding component would be to determine where everything lives - ie. the Makefile, make && make install etc). Just an idea I'm sure there are many other ideas to be had. I don't think I want to necessarily be a mentor this year, but there's more than enough of this list that will qualify. I would probably throw my hat in for the ultimate quintessential audio console which finally bridges jack and pulseaudio in an intuitive manner. jam-control Mach #2. Will definitely be available to co-mentor regards, Brendan [1] https://fedoraproject.org/wiki/Summer_coding_ideas_for_2013

All for Db
by twohot 10 Feb '13

10 Feb '13

So I rushed to my Fedora box trying to hum a tune into Audacity in Db (D-flat) major ... only, I dont trust my sense of pitch. So I decided to try a virtual keyboard to spot the Db frequency/pitch and was rather disappointed that Ubuntu was getting all the packaged versions. Bah! Alright, I compiled one (VMPK) and got jack-keyboard from the repo. The only problem now is that I have no idea how to start jackd. #jack forum at freenode isn't helping much. I couldnt even get a sound from ALSA in VMPK. HELP! So much for Db and I think we need an active IRC channel Regards Onyeibo

Re: [Fedora-music-list] Icon Pack
by Christopher Antila 08 Feb '13

08 Feb '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Brian: I'm wondering what these icons are for? If they are indeed intended to be functional (i.e., they will represent applications/programs, actions, places, resources, etc.) rather than decorative (i.e., they will be on the splash screen, desktop background, and marketing materials), I have a few suggestions. 1.) The drum set icon sticks out because it's much more detailed than the others. Generally, funcitonal icons should be as simple as posible. 2.) I don't know what source files you're using to generate the PNG images you sent, but ideally icons should be scalable SVG files. 3.) If you prefer PNG files, you could make different sizes of images, like most of the icons in the Oxygen set. If you do, when you make smaller icons, you'll probably want to change the metallic background to a gradient, and as you go even smaller, into a flat colour. I'm also not a graphic designer. My comments are things I remember from reading blog posts and developing icons for my own programs. In my case at least, it seemed that the more accurately I could depict something, the *less* obvious it was for other people!
