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