[ubuntu-us-nc] FOSS for audio production webcast on opensource.com

[adam at linkedlistcorruption.com]

Hi Mike!

Nice to digitally meet you

"COOL, i was thinking about doing my audio presentation (for the WNCLUG)"

What presentation do you do? I'd love to see/hear it. Also, what's WNCLUG? I do a lot with TriLUG here in the Triangle but if there's another LUG that might be interested in my presentation I'd love to spread the word!

"are you currently using the planetCCRMA packages with fedora?"

No, I never liked planetCCRMA. they're always a release or two behind Fedora and I've run into problems with package dependency conflicts. Some of those could very well have been rooted in my own ignorance but they made me gun shy none-the-less. Instead I recorded on UbuntuStudio. However, in Fedora 14 the Fedora folks collaborated with the planetCCRMA folks to get good audio packages in the Fedora base repos. They even put together a killer doc for audio on Fedora through the GSOC:

http://docs.fedoraproject.org/en-US/Fedora/14/html/Musicians_Guide/index.html

I recorded for a while on F14 and loved it. In my testing I saw about 50% less DSP CPU utilization in Ardour & JACK on F14 as compared to UbuntuStudio Lucid. I think this was because of jack-dmp being default in F14. I returned to UbuntuStudio on Maverick and found performance in line with F14. I just installed Natty last night. So far it is blowing my socks off. Unity fits my workflow perfectly and I'm seeing another major increase in performance on the same hardware as compared to Maverick. Very impressed indeed.

"i work with the ubuntustudio team a bit, mostly just testing and organizing, but we have been quite happy about the development of the -generic kernel, however quite sad that we didnt get the -lowlatency kernel pushed in the repos for natty since we actually do still need it, but hopefully before 12.04, we will have the one kernel..."

I've tested... and tested... and tested... and tested. Nothing touches the hard realtime kernel for performance. I still use the hard real time kerenl. On Fedora I build my own. Unfortunately I am far less competent on Debian based systems and don't understand GRUB 2 so I can't build my own real time kernels on Ubuntu. Instead I still use the creaky old linux-realtime 2.6.33-29.1 from abogani. I tested the 2.6.33-29.1 vs. the lowlatency kernel 2.6.38-8.42 for Natty and it lead to xruns and stutters on complex Ardour compositions whereas the realtime was smooth as butter. I'd love to not have to use the realtime kernel but as far as my testing has shown I'm convinced that we still need it; the lowlatency is not enough.

"i'll mark your show on my calendar and try and make it.."

Awesome :) I hope it is in some way informative or useful. I'll be givning a similar presentation at CarolinaCon at the end of the month so if you are interested come on out. Also, feel free to hit me on freenode if you want to talk audio. I'm zylogz80 in #ubuntustudio and a couple other places.

Thanks!
Adam

again in may since it got snowed out once... are you currently using the
planetCCRMA packages with fedora? how is natty working for you? i work with
the ubuntustudio team a bit, mostly just testing and organizing, but we have
been quite happy about the development of the -generic kernel, however quite
sad that we didnt get the -lowlatency kernel pushed in the repos for natty
since we actually do still need it, but hopefully before 12.04, we will have
the one kernel... i'll mark your show on my calendar and try and make it..
thanks for the heads up...
