| mossby | Figured if anyone knew, you guys would... what's the status on a RT kernel in Meerkat? is there a preferred or suggested workaround? | 04:57 |
|---|---|---|
| persia | The person who has been maintaining the RT kernels decided not to do it anymore, because it was more than a one-person job. | 04:59 |
| Monona | Some flash videos aren't working in Firefox (youtube is, vimeo isn't). I've updated my system, installed and run flash-aid add-on, and still no go. Any suggestions? I'm using Hardy 8.04 | 05:12 |
| persia | I'd recommend upgrading to lucid as a first step, and not using anything like flash-aid | 05:13 |
| persia | Install adobe-flashplugin (from Canonical's partner repo), or flashplugin-installer (from multiverse) | 05:13 |
| persia | Those ought work a lot better. | 05:13 |
| Monona | Yeah, I've only just got a stable audio production platform, and I kinda don't want to lose it. | 05:13 |
| Monona | I'll try those. | 05:14 |
| holstein | Monona: dual boot | 05:14 |
| holstein | install a lucid or maverick beside it | 05:14 |
| persia | Worth thinking about an upgrade to lucid anyway: hardy support for desktop-level stuff (including Studio) ends come April. | 05:17 |
| Monona | holstein: Let's see if these other plugins work. I'd rather just boot into one setup if I can. | 05:17 |
| persia | I'm not sure those are available for hardy: might be, might not be. | 05:18 |
| Monona | persia: How's rt-kernel stuff in Lucid? Like I said, it's taken me a while to get this setup working, and I'm worried an upgrade would involve rehashing all the what-not. | 05:19 |
| * holstein doesnt even have flash on the audio production box | 05:19 | |
| Monona | Although I suppose a dual boot would be ok to test stuff. | 05:19 |
| holstein | the -rt kernel is the one from karmic | 05:19 |
| persia | I think -rt in lucid is best-effort in a PPA, but that's still more than hardy which is what-you-have-today-with-no-security-fixes | 05:19 |
| holstein | plenty of PPA realtime kernels too | 05:19 |
| holstein | works great | 05:19 |
| Monona | What does PPA mean? | 05:20 |
| persia | holstein, Are there really plenty of them? Would it be possible to get the multiple people working on them to make one master one? | 05:20 |
| holstein | persia: between abogain and falks PPA | 05:20 |
| persia | Monona, PPA is a means by which Launchpad lets anyone make an archive. No promises, no guarantees, but there's stuff there that is different from what's in the regular repos. | 05:20 |
| persia | holstein, I think that's the same code. | 05:21 |
| holstein | is now | 05:21 |
| holstein | falks used to be patched for the proprietary graphics drivers | 05:21 |
| holstein | but i think abogani added that as well | 05:21 |
| holstein | persia: but yeah, i guess thats all the same kernel | 05:22 |
| holstein | still, works great for me Monona | 05:22 |
| holstein | i use lucid with falktx's ppa added | 05:22 |
| Monona | persia: Ah, ok. Like repositories but not official. | 05:22 |
| persia | Monona, Right. Very much not official, but present. | 05:23 |
| holstein | no reason not to run lucid instead of hardy | 05:23 |
| Monona | holstein: Yeah, I'm just frustrated with having to keep tweaking stuff. Everything was working fine, but somewhere in the last month flash got borked. | 05:23 |
| persia | The point being that if you really need supported realtime, you should stick with hardy, except you should be aware that support for desktop environments for hardy ends in April. | 05:23 |
| holstein | theres a meta-package now | 05:24 |
| holstein | sudo apt-get install ubuntu-restricted-extras | 05:24 |
| Monona | I mean, it's interesting learning how all this stuff works, but I just kinda want it to work. | 05:24 |
| holstein | i find lucid as stable as hardy was | 05:24 |
| holstein | if not more | 05:24 |
| Monona | Yeah, I've got that package. Good to know that Lucid is stable. That's LTS, right? | 05:25 |
| holstein | you must be back at like ardour 2.1 or something too | 05:25 |
| holstein | Monona: LTS :) | 05:25 |
| holstein | Monona: download a lucid live CD | 05:26 |
| holstein | and check your hardware | 05:26 |
| Monona | I only just last night actually figured out how to use ardour. Courtesy #opensourcemusicians. | 05:26 |
| holstein | Monona: OH | 05:26 |
| holstein | yeah, just go ahead and get lucid then | 05:26 |
| holstein | if your just starting to learn anyways | 05:26 |
| holstein | thats my vote :) | 05:27 |
| holstein | however | 05:27 |
| holstein | flash videos sometimes just dont work | 05:27 |
| holstein | for me | 05:27 |
| holstein | its a good thing that i dont care | 05:27 |
| Monona | Well, I've got my jack and puredata and seq24 and hydrogen all playing nicely with my Fast Track and Ozone. | 05:27 |
| holstein | AH | 05:27 |
| holstein | with that madfuload package? | 05:28 |
| Monona | Yeah, that's the one. I'm more worried about that getting messed up. Lots of troubleshooting. | 05:29 |
| holstein | sounds like your looking around for your cake | 05:31 |
| holstein | and hoping you can eat it ;) | 05:31 |
| Monona | I should try a dual boot into Lucid, just to see. Thing is, then the little time I have for making sounds turns into browsing ubuntu forums. | 05:31 |
| Monona | Oh, I've got my cake. At least until April... | 05:31 |
| holstein | eitherway, i say, dont let flash decide anything for you | 05:31 |
| Monona | Yeah, I hear you. Just there's fun stuff on vimeo. :-( | 05:33 |
| persia | Monona, Everything you listed is only going to have better driver support in lucid. | 05:33 |
| holstein | you can always try with a lucid live CD | 05:34 |
| holstein | and see how hard it is to get your gear running | 05:34 |
| Monona | persia: Even the m-audio stuff? It seemed like the Ozone was only barely supported. | 05:34 |
| holstein | should be totally easier | 05:34 |
| holstein | i got an maudio tranisit | 05:35 |
| holstein | used to be a bit of a pain | 05:35 |
| holstein | now its just sudo apt-get install madfuload | 05:35 |
| Monona | holstein: That sounds reasonable. Just gotta find a blank cd somewhere in these stacks... | 05:35 |
| persia | Monona, The key is that lucid has newer, updated, drivers, which tend to work on more hardware. If newer drivers break HW, folk tend to file bugs and try to fix with more attention than when HW just isn't supported yet. | 05:36 |
| persia | But, yeah, play with a LiveCD first. make sure the low-level stuff works. | 05:36 |
| Monona | How's nvidia support in Lucid? Last I checked rt-kernel and nvidia weren't playing nicely. | 05:36 |
| persia | They still don't. | 05:36 |
| persia | But they don't for hardy either, if I remember correctly. | 05:36 |
| persia | Problem mostly being that nvidia's binary stuff isn't realtime-safe. | 05:37 |
| Monona | Nope. I don't really need the video stuff anyway. | 05:37 |
| Monona | What does that mean? (just curious) | 05:37 |
| Monona | binary stuff =/= realtime-safe | 05:38 |
| persia | It was my understanding (and I haven't researched this in a couple years) that nvidia's kernel modules didn't support being interrupted mid-action because something else needed the timeslice. | 05:39 |
| persia | Might be fixed, but it would surprise me, as it would reduce observed graphics performance *and* isn't required for mainline linux compatibility. | 05:39 |
| Monona | Ah. Gotcha. Nvidia drivers are mostly useful for gaming and higher-end video production stuff, right? I never dug too deeply into what they actually did. | 05:40 |
| persia | They render and blit exceedingly fast. | 05:41 |
| persia | Good for gaming, video processing, video production, certain sorts of off-CPU computation, etc. | 05:41 |
| persia | I suppose someone could write some CUDA filters for audio, although I don't know if anyone has. | 05:41 |
| Monona | Yeah, stuff I don't so much need. What's CUDA? | 05:42 |
| persia | http://www.nvidia.com/object/cuda_home_new.html | 05:42 |
| persia | Basically, using the GPU as a co-processor for non-graphics stuff (say, as an extra DSP bank or something) | 05:43 |
| Monona | Sounds interesting, but for the time being I'm ok keeping my processing on the old-fashioned CPU. :-D | 05:45 |
| holstein | well | 05:45 |
| holstein | for us | 05:45 |
| holstein | audio guys | 05:46 |
| holstein | running audio plugins over there would be cool | 05:46 |
| persia | Yeah, well, lots of other places to play also :) | 05:49 |
| Monona | Makes sense. I think I've got a little while to go before I'm at that point. I'm mostly pretty stoked to have stuff consistently working. | 05:50 |
| Monona | Now I gotta actually sit down to make tunes. | 05:50 |
| holstein | its a good feeling Monona | 05:50 |
| holstein | hehe | 05:50 |
| holstein | i know that feeling too | 05:50 |
| Monona | Seriously. | 05:50 |
| holstein | its like 'now what' | 05:51 |
| persia | holstein, if you're interested, something like http://www.fixstars.com/en/products/gigaaccel180/ is another attractive sort of target (and probably has better linux support) | 05:51 |
| Monona | I started using ubuntu about 3 years ago, and finally got everything working July-ish. | 05:51 |
| holstein | persia: COOL | 05:51 |
| holstein | thats getting bookmarked | 05:52 |
| holstein | Monona: i did a gradual change over | 05:52 |
| holstein | i ran a laptop for day to day use for years | 05:53 |
| holstein | and just gradually added jobs for linux to do | 05:53 |
| Monona | persia: Again, over my head. What's that gizmo good for? | 05:53 |
| holstein | i blew out my last ntfs partition about a year ago | 05:54 |
| persia | Monona, high-speed dedicated processing. | 05:54 |
| persia | FixStars used to have a a few add-in cards with nVidia chips, which is why I looked there to get a URL, but they appear to have discontinued them outside Japan. | 05:55 |
| Monona | holstein: Yeah, I switched totally to Ubuntu and got started figuring out audio production at the same time. My budget is pretty much in the $0-FLOSS range. | 05:55 |
| Monona | persia: Yeah, probably past what would be useful for me right now. My buddy's got a system he's cooling with liquid nitrogen, but I figure I should learn to mix down tracks before I take any more leaps into hardware upgrading. | 05:58 |
| persia | Monona, It's very unlikely stuff like that is useful, especially because I don't think we have any software that takes advantage of it, beyond the vendor SDKs. | 05:58 |
| Monona | Interesting stuff, tho. | 05:58 |
| Monona | persia: Yeah, nowhere I'm looking go anytime soon. Although liquid nitrogen is pretty cool. | 06:00 |
| persia | Oh, it is indeed. | 06:02 |
| Monona | :-D | 06:03 |
| Monona | persia: What sort of production do you use Ubuntu for? | 06:03 |
| persia | I mostly just play with soundscapes. Most of my experience with real audio production has not involved computers as part of the production process. | 06:04 |
| holstein | persia: you do live DJ type stuff? | 06:05 |
| Monona | Soundscapes as in how? | 06:05 |
| persia | holstein, No, if I use prerecorded samples, they're just my own aquired sounds. | 06:07 |
| persia | Monona, So, you go record some things (I tend to mostly use impacts in various rooms). | 06:07 |
| Monona | I've been interested in using field recordings as source material for other productions (that's what i'm trying to do in pure data), but I've only recently started getting into folks making compositions from them. | 06:07 |
| persia | Then you put it through effects systems with feedback and delay to make the sounds more complex or different. | 06:08 |
| Monona | Yeah, that's really interesting to me. | 06:08 |
| persia | Then you loop it, or use MIDI to trigger samples, and maybe some knobs and buttons to change the effects. | 06:08 |
| Monona | What kind of set up do you have for that? | 06:08 |
| persia | I don't preserve what I do: I just play. | 06:08 |
| Monona | Ah, right on. | 06:08 |
| Monona | So you're using recordings that you're making live as source material? | 06:09 |
| persia | Yes, although most of my "recordings" are me hitting a mic with something hard once. | 06:12 |
| persia | impacts reverb in the real space, then the reverb profile creates frequency patterns which can be adjusted in effects systems (freq shift, band filters, loops, etc.). which then can be fed back into each other to achieve multichannel sound that varies over time. | 06:13 |
| persia | But what I do is not something that tends to result in anything like "music". The closest I got was once working with sooprelooper to generate enough harmonics to hit 120 bpm, which resulted in something someone else said "sounds like bad lounge music without the guitar". | 06:14 |
| Monona | Ha. | 06:14 |
| Monona | That's great. | 06:14 |
| Monona | It sounds like really interesting stuff. | 06:15 |
| persia | I guess. Just set up some effects filters with jackrack, chain them up (don't forget delays) with patchage, and say "Hello" into your mic. | 06:15 |
| persia | Connect some of the controllables to controls (qcontrol works if you don't have a control surface), and fiddle a bit. Use a loop tool if you want to havea backing track (or hydrogen if you want a real rhythm section) | 06:16 |
| Monona | You have any recordings? I'm intrigued... | 06:18 |
| Monona | I've been playing with heavily processed (mostly) field recordings in puredata, and I'm curious as to what other folks are doing on the more adventurous side of DSP. | 06:22 |
| persia | I don't record it. It's just noise, mostly. Sometimes interesting sounds or rhythms, but nothing that is worth saving. | 06:25 |
| Monona | Do you use the same fx/etc setup for your sound and just play with the presets, or change that up as well? I've always been into how even just basic delay can totally alter a sound. | 06:40 |
| persia | I never use the same setup twice: most of why I don't explain what I use in detail comes because it's really a matter of which apps catch my fancy that day. | 07:04 |
| merethan | Hi all | 13:23 |
| merethan | Maverick Meerkat Studio is already released | 13:24 |
| merethan | http://cdimage.ubuntu.com/ubuntustudio/releases/10.10/release/ | 13:24 |
| merethan | But the download page http://ubuntustudio.org/downloads still points to 10.04 | 13:24 |
| merethan | Webadmin around? | 13:25 |
| persia | no, which is the main issue. | 13:27 |
| persia | The web admin hasn't been around since release. | 13:27 |
| persia | the project leader has been hunting him down :) | 13:27 |
| jure_ | where can I get the real-time kernel for vanilla ubuntu? | 13:29 |
| persia | jure_, The person who was maintaining the realtime kernels has stopped doing so. Needs someone else to start maintaining them (or a team to form to maintain them) | 13:32 |
| jure_ | does that ... does that mean ... I'll have to compile the kernel myself? | 13:33 |
| persia | If you want realtime, probably, unless you can find someone else who will. | 13:34 |
| merethan | persia, the release is stable and all? | 14:00 |
| merethan | BTW, does Ubuntu Studio not have a RT kernel by default? | 14:02 |
| merethan | When doing MIDI that's not precisely an requirement but it really does improve performance. | 14:03 |
| merethan | Since my MIDI is on an USB2 wire, I need the least possible delay I can get.. | 14:04 |
| astraljava | merethan: No RT or alike kernel for Maverick. | 14:04 |
| merethan | shite | 14:04 |
| merethan | I 'll try it out anyway | 14:04 |
| jure_ | how to cat output to the speakers? | 14:33 |
| jure_ | cat /dev/urandom >> /dev/snd/pciC0D0c returns "file descriptor in bad state" | 14:43 |
| persia | jure_, Try `pacat` | 14:49 |
| jure_ | haha :) | 14:50 |
| jure_ | sounds like heavy rain | 14:50 |
| merethan | In the OSS days cat worked too | 14:52 |
| merethan | OSS is already back in town for a while already BTW | 14:52 |
| persia | cat > /dev/dsp still works if one turns on OSS compatibility, but it's lots less flexible. | 14:52 |
| obengdako | hi my qjackctl does not start some kind of ibus error | 14:59 |
| merethan | dbus? | 15:07 |
| jure_ | so, I need to set SND_REQ_RTCTIMER_DEFAULT to y? or is m enough? | 15:27 |
| jure_ | hm, seems like I can't access this option via menuconfig | 15:34 |
| jure_ | hm, I forced it in. wonder what will happen ... | 16:09 |
| astraljava | The universe most likely bursts. | 16:11 |
| jure_ | with a hacked kernel, you never know. | 16:12 |
| merethan | Or maybe it will freeze solid because of the coolness. | 16:18 |
| jure_ | anyway, if I don't make it on the next reboot, it's been nice hanging out here, guys | 16:19 |
| astraljava | jure_: Take care. :D | 16:21 |
| researcher1 | how to convert .flv file into .3gp | 18:36 |
| researcher1 | hello | 18:43 |
| astraljava | researcher1: Did you try google? First hit with keywords "convert flv into 3gp ubuntu" seems to give quite an acceptable answer... | 18:44 |
| researcher1 | astraljava: ok.Im trying | 18:44 |
| * merethan is buring the ISO | 18:46 | |
| merethan | researcher1, Arista is a reasonable encoder front-end | 18:47 |
| researcher1 | merethan: im trying | 18:47 |
| merethan | Obviously VLC can do the job too | 18:48 |
