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.

Fedora Jam tracking well

Currently number 5 out of 11 for torrent downloads! Not bad for the new kid. Its very quiet on this list at the moment, so tell us what you've been doing with music! Fedora / Linux / recording etc etc Me, I've been trying to organize my many samples into sfz format for use. Also found new interest in guitar (my new schecter rocks!) I'm no drummer, but have been studying drumming a lot lately to fill out some triggered recordings. Would love to hear other peoples experience in this area. kick out the jams Brendan

It's been a long time coming but as of now Fedora has its own audio spin. Thanks and congratulations to everyone who helped make this happen. You can download there spin here: http://spins.fedoraproject.org/jam-kde/ http://spins.fedoraproject.org/

Hello, Thanks for all of the information and discussion on this topic. I took a trip to a couple of audio hardware dealers yesterday and tried plugging in a couple of different audio interfaces to see if they would work out of the box with my laptop running fedora18. Here is what I found: The presonus 44vsl usb 2.0 was not recognized by my system. Upon opening system settings >> sound and then looking for the device under the "output" and "input" tabs, there was nothing to select except for my default on-board mic and speakers. The presonus 22vsl usb 2.0 provided the most hope of all of the devices I tried. I was able to select it in system settings and then also select it in the devices section of audacity's preferences menu. Upon connecting a mic and headphones I was able to both record into audacity and monitor output from audacity through the headphones. The one drawback I had with presonus 22vsl was that I was unable to play music from neither rhythmbox nor amarok. Just as important for me as recording and monitoring sound I create with audacity (or some other sound editing software) is the ability to listen to music for inspiration and new ideas. I could hook up monitors (speakers) directly to my headphone jack on my computer, but I'd like to take advantage of the preamps on board the audio interface. I then went to a second store and connected a tascom US-600. The tascom was not recognized at all by my laptop. I tried rebooting with the device connected and still nothing in system settings or in audacity. The final device I tried was the Focusrite 2i4. I was excited to see that it was recognized in system settings. I was able to select the Focusrite as an output device, but when I selected it as an input device my system settings window would crash. I was able to select the device for both input and output in audacity. I was able to listen to playback in audacity, but the unable to record into audacity through a mic. I still have not purchased anything. I'd like to hear some feedback on how I might be able to solve the issue with the presonus 22vsl not being able to output signals from amarok and rhythmbox. Thanks and hope some of you find this information useful.

I think Kevin's proposal is reasonable, I'm pretty sure we can manage 2 people to test the Jam ISOs at Alpha/Beta and Final. If you have any feedback I'd recommend replying on the spins list rather than here, so the other Spins SIGs can hear your thoughts. Brendan

Are you able to route audio playback through it from a media player (amarok, rhythmbox) successfully? I found the Fast Track available here: http://www.guitarcenter.com/M-Audio-Fast-Track-Ultra-USB-2-0-Audio-Interfac… What version of fedora are you using it with? and what software (jack, audacity, ardour)?

Compatible USB Audio Interface
by profiles 27 Jul '13

27 Jul '13

Hello, I am a musician and recently joined this mailing list. I use Fedora18 and would like to use it to create music. I am having trouble getting off the ground as I have not identified a USB Audio Interface that is compatible with Fedora. I have visited the ALSA soundcard matrix wiki and a number of forums in hopes of finding a device. Unfortunately many of the models and makes talked about are a few years old now and, frequently, are no longer available from distributors. I imagine a few people on this list use some sort of soundcard to test/use all of the great software that is being created for linux users. I am inviting suggestions from people with experience in the application of audio hardware in the fedora environment. I am looking for a device that uses an independent power plug, connects with usb 2.0, and has both MIDI and analogue inputs and outputs. A device similar to this would be great: http://www.presonus.com/products/AudioBox-44VSL/media Thanks and I look forward to offering feedback on software once I am up and running. -Occhi

If not start one please! (i don't use a mobile but I'm sure pretty much everyone else does) Anyway man, what have you been up to with music recently? I went to a hotrod festival about 100k's from berlin with some good punk, and the next week to a Goa trance party. Both good, both with lots of mosquitos. All good when music is king B
