| holstein | i say for JACK... 512 frames/period, sample rate 44,100, and periods/buffer 3 | 01:26 |
|---|---|---|
| holstein | oops... | 01:26 |
| swamptin | Hi all | 02:16 |
| holstein | o/ | 02:16 |
| swamptin | How goes? | 02:16 |
| holstein | not bad, and you? | 02:16 |
| swamptin | Sitting in work dossing | 02:16 |
| swamptin | trying to work out if a machine spec is compatable with UbuntuStudio before I buy it | 02:17 |
| holstein | the machine? | 02:18 |
| holstein | maybe take a live CD to it if you can | 02:18 |
| holstein | but, its really hard to say | 02:18 |
| swamptin | can't unfortunately. I'll be buying it online. | 02:18 |
| holstein | well, the machine doesnt matter so much | 02:18 |
| holstein | the interface does | 02:19 |
| holstein | http://www.alsa-project.org/main/index.php/Matrix:Main | 02:19 |
| swamptin | There's been reports of Ubuntu being fine with it, and it seems to support the chipset | 02:19 |
| holstein | http://www.ffado.org/ | 02:19 |
| holstein | ubuntustudio = ubuntu | 02:19 |
| holstein | so it should be fine | 02:19 |
| swamptin | Yeah, but the real question I want answered is audio support, cause otherwise it's not really gonna work for me. So research research research | 02:20 |
| holstein | well, the internal sound card doesnt matter anyways | 02:20 |
| holstein | what interface do you have? | 02:20 |
| holstein | you shoul djust take that with you to the new machine | 02:21 |
| swamptin | Well, I have an MAudio U-Control, that used to work fine iirc | 02:22 |
| holstein | i like to either have a texas instruments firewire chipset onboard for my presonus firepod, or whatever firewire device i switch to in the future, or i like to be able to disable the onboard firewire and use a texas instuments PCI card | 02:22 |
| holstein | swamptin: USB is USB | 02:22 |
| holstein | so, that'll work just like it did | 02:23 |
| swamptin | well, that means that I have a solution to the problem if the on board sound isn't ideal :) | 02:23 |
| holstein | well, what im getting at is | 02:23 |
| holstein | onboard sound is *not* ideal | 02:23 |
| holstein | *all* of them | 02:23 |
| holstein | any of them | 02:24 |
| holstein | so, you dont want to try doing any pro audio with onboard sound | 02:24 |
| holstein | but, anything alsa uses, JACK should use | 02:24 |
| swamptin | Yeah, I know I want to avoid on board stuff. Just got a new desk the other week, but it ain't usb, which sucks. Works mind, works fine and dandy | 02:25 |
| swamptin | I'll just need to upgrade it eventually. | 02:25 |
| holstein | no onboard USB? | 02:26 |
| holstein | get a USB pci card | 02:26 |
| holstein | i got one for $5 US at the charity shop | 02:26 |
| swamptin | The audio mixing desk, sorry | 02:26 |
| swamptin | not desktop | 02:26 |
| holstein | its got some way to export i assume | 02:27 |
| holstein | burn CD's or something | 02:27 |
| holstein | import into ardour | 02:27 |
| swamptin | Just a phono out | 02:27 |
| swamptin | but that's all you need. My usb soundcard has phono in, I'm happy :) | 02:28 |
| holstein | i suppose | 02:28 |
| holstein | i wouldnt want to go analog to digital to analog to digital again | 02:28 |
| holstein | then to analog to hear it finally ;) | 02:29 |
| swamptin | hah | 02:29 |
| holstein | i had one with a lightpipe out | 02:29 |
| holstein | some kind of roland vs880 or something | 02:29 |
| holstein | that worked OK | 02:29 |
| swamptin | Well, I'm not planning on putting the BBC production standards to shame anytime soon | 02:29 |
| holstein | yeah, but all you need is a way to get digital into the computer, and you're not juggling clocks | 02:30 |
| holstein | i mean, 99% of whats wrong im project studios is just signal path | 02:30 |
| * holstein totally speculates | 02:31 | |
| swamptin | true. It'll be my next upgrade plan. But I just wanted to be able to get back recording immediately | 02:31 |
| swamptin | You'd be right, assuming the cable lengths aren't being kept to a minimum | 02:31 |
| swamptin | And of course, there is a loss in quality each time you move from one format to another. | 02:32 |
| holstein | depends | 02:33 |
| holstein | but, you dont want to leave digital unless you have a good reason | 02:33 |
| swamptin | certainly not. | 02:36 |
| jasonmchristos | How do I get the lowlatency kernel installed if my boot part is (ro) ? | 04:18 |
| holstein | ro? | 04:19 |
| jasonmchristos | read only | 04:19 |
| jasonmchristos | at mount | 04:19 |
| holstein | jasonmchristos: we dont have a lowlatency kernel, so you add a ppa | 04:19 |
| holstein | i wouldnt worry about it though | 04:19 |
| holstein | you probably dont need it | 04:19 |
| holstein | but, you'll need to write to install a kernel | 04:19 |
| jasonmchristos | Well the recording has a lot of noise. | 04:19 |
| holstein | jasonmchristos: that wont help | 04:20 |
| holstein | this would get you lower latency | 04:20 |
| holstein | when using JACK | 04:20 |
| holstein | noise is introduced from your sound card likely | 04:20 |
| holstein | proably an internal card | 04:21 |
| holstein | you might here the computer in the line in or the mic | 04:21 |
| holstein | but, the kernel wont help with that | 04:21 |
| holstein | maybe some cheaper USB interface would help | 04:21 |
| holstein | http://www.behringer.com/EN/Products/UCA202.aspx for example | 04:21 |
| jasonmchristos | Well when rcording without jack its a high pitched whine, when starting jack it becomes crackle. | 04:21 |
| jasonmchristos | Run through with me for learning purpose if you will. | 04:22 |
| jasonmchristos | Why the difference in noise with/without jack? | 04:23 |
| holstein | not sure | 04:23 |
| holstein | driver? | 04:23 |
| holstein | maybe just trying to claim access to the hardware | 04:23 |
| holstein | the crackle could be that you are trying to push JACK too hard | 04:23 |
| jasonmchristos | ALSA is selected in jack and you know that the default desktop uses pulse which is alsa based. | 04:23 |
| holstein | sure | 04:24 |
| holstein | thats plausible | 04:24 |
| holstein | http://gnuguitarinux.sourceforge.net/ has an RT kernel AFAIK | 04:24 |
| holstein | and http://www.bandshed.net/AVLinux.html too | 04:24 |
| holstein | they are LIVE ^^ | 04:24 |
| holstein | we will be switching to a live installer soon as well :) | 04:25 |
| holstein | but, til then, you can try one of those for an ubuntu-like comparison of your hardware with a lowlatency kernel | 04:25 |
| holstein | but, thats not the issue | 04:25 |
| jasonmchristos | I found someone elses settings and changed jack frames/period to 256 from the default settings this was the only difference. | 04:25 |
| holstein | right | 04:26 |
| holstein | i would try 1024 | 04:26 |
| jasonmchristos | Whats the signifigaec of frames/period ? | 04:26 |
| holstein | latency | 04:26 |
| jasonmchristos | Let me try and see what happens. | 04:26 |
| jasonmchristos | BTW, live installer = bad idea | 04:26 |
| holstein | yeah? | 04:27 |
| holstein | i think its a great way to see how the hardware works with JACK and the other software | 04:27 |
| holstein | i would have never made it to linux audio without the 64studio live CD | 04:27 |
| holstein | but, thats just my opinion | 04:28 |
| jasonmchristos | you arent accomplishing much | 04:28 |
| holstein | jasonmchristos: its this cycle we are talking about it | 04:28 |
| holstein | so join #ubuntustudio-devel and the mailing lists and share your opinion | 04:28 |
| holstein | i personally think we are accomplishing a lot | 04:28 |
| holstein | an avenue for folks to test hardware | 04:28 |
| holstein | an arguably more modern and fresher looking install experience | 04:29 |
| holstein | more congruence with the main ubuntu experience | 04:29 |
| jasonmchristos | no its counterproductive | 04:29 |
| jasonmchristos | its not a valid test of performance at all | 04:30 |
| jasonmchristos | will give the wrong impression | 04:30 |
| holstein | i disagree | 04:31 |
| holstein | what audio distros have you tried live? | 04:31 |
| jasonmchristos | mainly just this one tried dynebolic long ago holstein wouldnt boot | 04:34 |
| jasonmchristos | holstein, yeah it seems that 256 is crackle and 1024 is whin | 04:35 |
| jasonmchristos | whine | 04:35 |
| jasonmchristos | why is thia | 04:35 |
| jasonmchristos | must be the soundcard | 04:37 |
| jasonmchristos | What is latency the time it takes the DSP to output from input ? | 04:38 |
| holstein | bascially | 04:39 |
| holstein | thats not your issue though | 04:39 |
| jasonmchristos | Iwell the Period/Frames is listed as latency in ardour | 04:39 |
| jasonmchristos | and thats what changes the noise pattern | 04:39 |
| holstein | yup | 04:40 |
| holstein | but, its just an internal card right? | 04:40 |
| holstein | you dont want that | 04:40 |
| jasonmchristos | So why do you say that isnt the isue? | 04:40 |
| holstein | that card i linked is $30 | 04:40 |
| holstein | US | 04:40 |
| holstein | get you one of thoes | 04:40 |
| holstein | those* | 04:40 |
| jasonmchristos | I have a little dragon andrea naturally speaking USB mic box. | 04:40 |
| holstein | it'll improve your studio *way* more than 30 bucks worth | 04:40 |
| holstein | yeah, not a USB mic either | 04:41 |
| holstein | not something you would use to conference call | 04:41 |
| holstein | something resembling something from a studio | 04:41 |
| jasonmchristos | Why would adjusting the latency cause noise pattern changes , because its internal. | 04:41 |
| jasonmchristos | Are you a salesman or a supporter? | 04:42 |
| jasonmchristos | Help me figure this out. | 04:42 |
| holstein | well, i have it figured out | 04:42 |
| holstein | you are using really inappropriate hardware | 04:43 |
| holstein | im not trying to sell you something | 04:43 |
| holstein | im trying to save you some time/energy | 04:43 |
| holstein | you'll never make a dollare out of 15 cents | 04:43 |
| holstein | that is literally the cheapest device you can get away with in my opinion | 04:43 |
| holstein | its USB, so its not going to pick up the internals of the machine so much | 04:43 |
| holstein | the whirz and buzzes | 04:44 |
| holstein | its supported well | 04:44 |
| jasonmchristos | ok looks useful | 04:44 |
| holstein | its got stereo line ins | 04:44 |
| jasonmchristos | thanks for the link | 04:44 |
| jasonmchristos | but i want to understand why the noise pattern changes | 04:44 |
| holstein | i have several internal/onboard sound cards | 04:44 |
| holstein | they all do something to that degree | 04:44 |
| holstein | lick | 04:44 |
| holstein | click* | 04:44 |
| holstein | buzz | 04:44 |
| holstein | whatever | 04:44 |
| holstein | i dont use them for anything missiong critical | 04:45 |
| holstein | ever | 04:45 |
| holstein | its like asking why your dial-up modem isnt delivering wifi | 04:45 |
| jasonmchristos | someone pawned my atr100 | 04:45 |
| holstein | i mean, it *is* capable of networking | 04:45 |
| holstein | but, that doesnt mean you should use it | 04:45 |
| jasonmchristos | no im asking a simple question whats the cause of correlation between changing noise pattern and the latency setting on jack | 04:46 |
| jasonmchristos | if it was em interference the whine would be present on both settings | 04:46 |
| jasonmchristos | the craclking im guessing is because im requesting a latency quicker than the card delivers | 04:47 |
| holstein | the JACK driver | 04:47 |
| holstein | and how its communicating with the hardware | 04:47 |
| holstein | you can catch las over in #ardour | 04:47 |
| holstein | he's the main guy that wrote it | 04:47 |
| jasonmchristos | ok | 04:47 |
| holstein | you can see if he can explain more indepth | 04:47 |
| holstein | it never surprises me when i here that | 04:47 |
| jasonmchristos | ok thanks for the link to the soundcard | 04:47 |
| holstein | hear* | 04:47 |
| holstein | and i have noticed that | 04:48 |
| holstein | i have never found a way to make it clean enough to use | 04:48 |
| holstein | you wont find a JACK setting that will make that card quiet | 04:48 |
| holstein | so, i havent bothered to look into why it affects the sound that way | 04:48 |
| holstein | but, its grabbing that card | 04:48 |
| holstein | JACK | 04:48 |
| holstein | and the setttings are telling JACK what to do with it | 04:49 |
| holstein | and its not liking it | 04:49 |
| holstein | and i attribute that to the fact that it was designed to plug a mic in and do telephony at best | 04:49 |
| holstein | not audio recording/production | 04:49 |
| jasonmchristos | agreed | 04:52 |
| jasonmchristos | but I want to learn anyway | 04:52 |
| holstein | you can learn a lot about JACK and the connections from that hardware | 04:53 |
| holstein | you can do MIDI too | 04:53 |
| holstein | keep it where things are 'rendered' in the box | 04:53 |
| holstein | not recorded into it | 04:53 |
| holstein | that'll make whatever you create clean | 04:53 |
| jasonmchristos | which box | 04:54 |
| holstein | the computer | 04:57 |
| holstein | your computer | 04:57 |
| holstein | that doesnt require a fancy sound card, though it would be nice to hear it somewhat decently | 04:57 |
| jasonmchristos | ok this german card looks good | 05:32 |
| jasonmchristos | mabe i could build my own | 05:32 |
| jasonmchristos | but i guess the germans need some money | 05:33 |
| holstein | im sure you could.... the lowlatency kernel can help with xruns | 05:33 |
| holstein | which would explain why the crackle goes away | 05:33 |
| holstein | at 1024 | 05:33 |
| jasonmchristos | right so how would i try this since my kernel is on read only | 05:34 |
| jasonmchristos | is that igor guy really a dev r is he a decepticon trying to swap out kernals ? | 05:35 |
| holstein | change to write | 05:35 |
| holstein | try one of the live CD's with a lowlatency kernel | 05:35 |
| jasonmchristos | ok fine | 05:35 |
| jasonmchristos | link to download the live cd please | 05:35 |
| holstein | depends really | 05:36 |
| holstein | AVLinux is debian based, but one of the bigger iso's with more features | 05:36 |
| holstein | gnuguitarinux is ubuntu based, and failry current | 05:36 |
| holstein | http://gnuguitarinux.sourceforge.net/ | 05:37 |
| holstein | http://sourceforge.net/projects/gnuguitarinux/files/gnuguitarinux-1.1_2.iso/download | 05:37 |
| jasonmchristos | well ive got a ppa | 05:40 |
| jasonmchristos | is this guy an ubuntu studio dev? | 05:40 |
| jasonmchristos | its going to be quicker for me to just install a kernel | 05:40 |
| jasonmchristos | rather than an entire live cd | 05:41 |
| holstein | what guy? | 05:42 |
| holstein | do what you chose | 05:42 |
| holstein | either will let you try a lowlatency kernel with your hardware | 05:43 |
| holstein | i would just install a kernel from https://launchpad.net/~abogani/+archive/ppa | 05:43 |
| holstein | but if you dont want to break your setup, do the live CD | 05:43 |
| jasonmchristos | holstein, if i remember correctly if the kernel doesnt work the other kernels remain installed and you can select them from the grub menu | 05:44 |
| jasonmchristos | is there any setting in these new distros that delete the old kernel by default ? | 05:44 |
| holstein | depends on how you have it setup, but yeah... i have several kernels on most laptops i use | 05:45 |
| holstein | jasonmchristos: i dont know what distro you are using, and how you are using it read only | 05:45 |
| jasonmchristos | im using 10.11 | 05:45 |
| holstein | i know that on ubuntu theres nothing that auto cleans kernels | 05:45 |
| holstein | 10.10? | 05:45 |
| holstein | 10.04? | 05:45 |
| holstein | 11.10? | 05:46 |
| jasonmchristos | i just during partitioning made a seperate /boot and set it to read only at mount | 05:46 |
| jasonmchristos | 11.10 | 05:46 |
| holstein | then you shoul be fine | 05:46 |
| holstein | you can go in now and edit grub2 to show "unhide" the menu | 05:47 |
| jasonmchristos | ok so i guess i have to change the mount options to write | 05:47 |
| holstein | you can press shift there at boot, and you should see the list | 05:47 |
| holstein | i usually reference the grub2 wiki for how to edit that file | 05:47 |
| jasonmchristos | how do i download all of the necisarry packages prior to installation ? | 05:47 |
| jasonmchristos | i have the ppa installed | 05:47 |
| jasonmchristos | but i just want to download with dependancys withou installing | 05:48 |
| jasonmchristos | then i will reboot in write mode to install | 05:48 |
| holstein | should be all in the PPA | 05:48 |
| holstein | just the header right? | 05:48 |
| holstein | doesnt need much | 05:48 |
| jasonmchristos | needs 2 packages i think | 05:48 |
| holstein | right | 05:49 |
| holstein | the kernel and the header? | 05:49 |
| jasonmchristos | is there a way to tell synaptic to cache them without installing ? | 05:49 |
| holstein | im sure there is | 05:49 |
| holstein | i tyically use apt or aptitude | 05:49 |
| jasonmchristos | k | 05:50 |
| jasonmchristos | holstein, sorry to bug with a basic thing but whats the file that specifies th mount options ? | 05:57 |
| holstein | jasonmchristos: /etc/fstab ? | 06:01 |
| jasonmchristos | ty | 06:01 |
| jasonmchristos | later | 06:08 |
| jasonmchristos | http://gnuguitarinux.sourceforge.net/ | 06:11 |
| jasonmchristos | I don't like sourcforge so much | 06:11 |
| jasonmchristos | I don't think they are honest with thier donations system. | 06:11 |
| jasonmchristos | http://www.behringer.com/EN/Products/UCA202.aspx | 06:11 |
| jasonmchristos | Will check this out. | 06:11 |
| jasonmchristos | hmm, why arent these showing up in my url grabber | 06:13 |
| sekisushai | hello | 20:30 |
| sekisushai | I would like to know if it's possible to straight install kde desktop during the installation process | 20:30 |
| sekisushai | to have a kind of kubuntu studio.. | 20:31 |
| astraljava | Not during the installation, but after that, sure. | 20:33 |
| sekisushai | so what do you advice, just install the minimum like xfce desktop | 20:33 |
| sekisushai | and then kde desktop ? | 20:33 |
| astraljava | Yes, that's what I would do. | 20:34 |
| sekisushai | and what about installing kubuntu and then install some package to change in ubuntu studio | 20:34 |
| sekisushai | at the end it's the same results ? | 20:34 |
| sekisushai | i mean, whatever installation cd i get, i then can change my ubuntu version by installing some package ?? | 20:35 |
| astraljava | That way works too. Just that by default, you'll have the desktop you last installed. You will have to choose which DE you log into at the greeter. | 20:35 |
| sekisushai | hum ok | 20:36 |
| sekisushai | so fundamentally any ubuntu version can be changed easily in an other one ? | 20:36 |
| astraljava | Very much so. | 20:36 |
| sekisushai | ok | 20:36 |
| sekisushai | thus, i'm gonna use the ubuntustudio installation cd | 20:36 |
| sekisushai | thanks ;) | 20:36 |
| astraljava | No prob, glad to be of assistance. | 20:37 |
| jfb86 | hello and cheers everyone!! :) | 23:12 |
| jfb86 | i tried 11.10, and i returned to 11.04... | 23:13 |
| jfb86 | is there anyone in that case? thx | 23:14 |
| jfb86 | i foud differences that don't please to me. excuse my english if i don't use the right words | 23:16 |
