sirriffsalotzequence: worse.. I'd have to reinstall my computer.. I'd be dead with a nuke, so would not have to rebuild the town00:00
=== qwerty is now known as Guest33894
martlI am running lubuntu on a laptop. The laptop won't boot To the ubuntustudio 12.10 disk. So I was thinking of just downloading a few programs to get me able to record my voice, acoustic guitar and electric bass, with a drum track of some kind more as a timing thing for the other instruments.03:37
martlWill audacity and hydrogen do this or will I need jacj to put it btogether ?03:39
martljack...03:39
martlthanks for having a look03:39
shai_haludaudacity does not need jack. hydrogen does03:39
martlis there a drum kit that will ork with audacity ?03:40
martlwork03:40
Len-nbBut audacity is not the best tracking SW. Great audio file editor though.03:40
martldo i need ardour then ?03:41
shai_haludardour, as i understand is way better than audacity. i know it has a lot less hiss in the rocordings i have made, than those i made with audacity03:41
Len-nbYou might want to try LMMS or gmorgan.03:41
holsteinmartl: you can export from hydrogen, an open it wherever you like03:41
shai_haludlmms works without jack too03:41
martlwill lmms record live insstruments ?03:42
shai_haludthat i do not know03:42
shai_haludanyone?03:42
shai_haludi use it for making synth stuff03:42
Len-nbWhile audacity and ardour have the ability to record at the same quality, ardour is easier to use for track at a time recording.03:42
martlall i want to do is mimic  a tascam type set up03:42
Len-nbLMMS does not record audio at this time.03:43
shai_haludmmm03:43
shai_haludi was curious about that myself03:43
martlwhat doi people do when they have instruments and they want to cfreate a one man band song ?03:43
Len-nbLMMS suggests using ardour to record a wav and then import that wav as a sample.03:43
Len-nbI use ardour03:44
Len-nbSome people use qtractor and I think rose garden works too03:44
shai_haludholstein: Zequence got me straightened out with firefox/jack03:44
Len-nbJack is not bad or hard.03:44
holsteinshai_halud: i knew he could ;)03:45
shai_haludAnd i have begun using ardour tonight03:45
martlsomething simple with minimallearning curve would be nice..03:45
shai_haludrecorded 3-4 songs already03:45
hectorlopezhttp://parumi.org/curso_produccion_musical_linux/ its in spanish but you can translate03:45
martltoda?03:45
shai_haludhehe03:45
hectorlopeza very very nice tutorial :D03:45
martltoday?03:45
shai_haludtu save http:translate.google.com ?03:46
holsteinshai_halud: congrats03:46
martlthanks03:46
shai_haludholstein: tyvm03:46
hectorlopezhttp://www.youtube.com/watch?v=lI0eddZjQEo&feature=plcp03:47
hectorlopezand a video too in spanish hehe but its a video to use jack, ardour and midi editors03:47
hectorlopezunder linux03:47
martl youtube translaator..hehe03:47
hectorlopezonly 4 wacht ? :P03:48
martlfirst thing I need is n adaptor for my mic03:50
martl10103:50
holsteinan adapter?03:50
Len-nbYou mean like a preamp?03:50
martlfrom 1/4 '03:50
martlto mini03:51
holsteini try and use as few adapters as possible.. i would try and get something with an xlr input that goes right to hard disk03:51
holsteinmartl: just keep in mind, you'll never hear anything on the radio, or see a studio recording with a mic into a mini jack like that03:51
holsteinmartl: thats more for skype.. not that you cant make something with it.. its just not that much more these days to get a USB interface with a decent preamp.. and it makes a *huge* difference03:52
Len-nbThe mic pre behind a mini jack will be quite noisy03:52
martlyes ...but what else does one do to plug in a mike ?03:52
Len-nbAudio adaptor03:52
holsteinmartl: plug it right into a preamp.. xlr cable..03:53
martlpreamp...sounds like money03:53
Len-nbI have had some success using an external pre into line in, but still not as good as a proper audio Interface03:53
holsteinmartl: as i said, there are some decent usb interfaces with preamps these days.. and its well worth the $$03:53
holsteinmartl: it'll be about what you'd pay for an hour or 2 in a pro studio, and it'll make it where you can better emulate the work flow a professional would be doing03:54
Len-nbART USBDualPre03:54
martlSo...an adapter will cause issues ?03:54
holsteinmartl: try it03:54
Len-nbThe internal pre will cause issues03:54
holsteinmartl: you might find why a studio would *never* use one03:55
martlI have to run down to radio shack....see what they have03:55
Len-nbMusic store.03:55
martlthat bad huh?03:55
Len-nbWhat kind of mic do you have?03:55
martlmusic store...not rdio shack ?03:55
holsteinmartl: as a person who used to "run down to radio shack", an interface, will *greatly* improve your sound.. for about $100 or so.. maybe $150 would be all you would need03:55
martlan old shure I think03:55
Len-nbCould be worse. Good for a start.03:56
martlPrologue03:56
Len-nbThe ART dual USBpre is $100. Plug and play with  linux03:56
martl10H03:57
holsteinLen-nb: is it? ART is nice kit03:57
holsteinLen-nb: i didnt realize it was plug and play03:57
Len-nbIt is USB 1.103:57
holsteinmartl: that art would step you up significantly03:57
holsteinfor the one or 2 channels, usb 1.1 is fine03:57
Len-nbI take my computer to the music store and try them before I buy03:57
martloh..ok...well lemme try to record anything ferstarters03:58
holsteinand the price is great, and its made for audio production03:58
Len-nbnetbooks are good for that.03:58
martlI have to admit that I do have ubuntustudio on my desktop but have yet to record a thing...I wanted to use my laptop03:59
Len-nbI've done both03:59
Len-nb(netbook and dessktop)04:00
martlI ahve about 12 tunes I did on a tascam that need to be perfected ...04:00
martlor finished04:00
Len-nbThe ART pre I got is the tube one it is a bit more money, but the basic one was nice too04:01
Len-nbThe tascam is digital or tape?04:01
martlPlug into art with a regular jack then plug art into computer through usb ?04:01
martltape04:01
martl199204:02
Len-nbYa, the art plugs into the usb and has both 1/4 inch and xlr inputs04:02
Len-nbI have a yamaha from the same era.04:02
martlok...beltb drive04:03
Len-nb4 track casette04:03
martlright04:03
Len-nbThe tascam might sound better than the internal sound card.04:03
martlI dont care.I want to move to computer04:04
Len-nbThe mic preamp in my net book is not as good as my Yamaha was.04:04
martlSound cards are transitory04:04
martlI can spend later04:05
Len-nbOK, been there too.04:05
martlI jsst want to record a g chord.....04:05
martlanything04:05
martlok...then a c then a d04:05
Len-nbDo you have an amp04:05
martlno04:05
martl I used topplug into the teac04:06
Len-nbdo you still have the teac?04:06
martlyes04:06
Len-nbDoes it have a line out04:06
martlyep04:06
Len-nbUse it as a pre amp04:06
martl.do we need to preamp?04:07
Len-nbIs it the one with the two channel mixer or the four?04:07
martlit has several...404:07
Len-nbYa, the mic is -50db line is -1004:08
Len-nbthe preamp will bring the level up to -10 which is line in.04:08
martlok04:08
Len-nb (consumer line, Profesional line is +4))04:09
martlCan I use my Alessis drum machine then ?through the teac?04:09
Len-nbYes.04:09
martlThat might e a simpler styart04:10
martlless curve04:10
Len-nbBasically, you would be using your computer to replace tape.04:10
Len-nbOnce you get sound in there, you can learn the work flow.04:10
Len-nbYou would still only be able to use one or two channels depending on what your internal audio Interface supports04:12
martlSo a mike plugged direct is too small a sound then ?04:12
Len-nbThere is an internal mic preamp, but I found this one really noisy... lots of hiss04:13
Len-nbIt is like the difference from your teac to the average minicassete from the same era.04:13
martlthere is no comparison04:14
Len-nbIt would take the same adaptor...04:15
Len-nb(I think)04:15
Len-nbOr a stereo y, strereo mini to two rca.04:16
martlHey thanks..Len-nb...gotta go shopping...be back later04:19
Len-nbmartl, adaptors are cheap04:19
Len-nbC ya04:19
alexandrosHello everybody05:01
alexandrosI just installed a fresh ubuntu studio 12.10 on my p.c and as I had been using last years Kubuntu, I would like to ask you whether installing KDE applications (like kile) would trigger any kind of problems with the XFCE environment?05:02
holsteinalexandros: shouldnt.. you can also just install kubuntu and use whatever audio apps yoyu want05:03
alexandroshostein: hi mike (I know your name already in the ubustudio community - thanks for all your work by the way ;) ), do you mean installing kubuntu desktop on top of the ubuntu studio installation, right? ?05:07
holsteinalexandros: cheers!05:07
Guest33894you can05:07
holsteinalexandros: either really.. whatever you are more comfortable with as a base is what i would suggest05:07
holsteinno reason not to use KDE if thats what you like05:07
alexandrosOK! that's good news. I thought (form discussions in the past in the LAU list) that the desktop environment could potentially introduce xruns or other minor isuues in the audio flow - it seems that this is not the case anymore..?05:09
holsteinalexandros: shouldnt..05:10
holsteinalexandros: check out KXstudio if just for the comparison in setup.. its KDE with ubuntu base05:11
alexandrosthanks Mike, I will05:11
holsteinalexandros: i would say disabling cpu throttling and tweaks like that would be more noticable for xruns than the DE05:12
holsteinalexandros: also, #opensourcemusicans can be a helpful resource05:15
alexandrosMIke, thanks for your kind feedback, however, I must say that I am a noob in this sense, just use the terminal to install/remove applications :). Would you have any further hints for starting configuring the pc -if necessary for better audio production- some kind of guides..?05:15
alexandrosOK, you were faster.. :)05:15
holsteinalexandros: i would just get started, and ask if you have issues... you might be just fine :)05:15
alexandrosTrue. However I do have a lot of XRUNS in the newly installed ubuntu studio and I would be interested to find out if there are ways to make the recording of my guitar via the Focusrite Scarlett 2i4 usb audio interface better (which by the way worked out-of-the-box)...05:18
holsteinalexandros: i would disable CPU stepping... relax jack settings... check irq ports.. unplug other USB hardware05:19
alexandroshostein: thank you Mike, I do keep a note of your feedback. However, as I am a noob, I really do not know how to do the tweaks you mention - are there really any kind of "best practices" or "officially" how-to's for that purpose for a beginner user of ubuntustudio... or do I have to leave my instinct guide me :) ? Any recommendations would be more than welcomed :)05:24
holstein!proaudio | alexandros this might help05:25
ubottualexandros this might help: For information on professional audio tools in Ubuntu, see https://help.ubuntu.com/community/UbuntuStudio/ProAudioIntro05:25
holsteinother than that, just searching.. i made a desktop button that disables my CPU govenor on my audio workstation05:25
holsteinyou can run cat /proc/interrupts and see if any other devices share your USB hardware05:26
holsteinyou can always just relax the JACK settings.. just go to 2048 frames/period05:27
alexandrosThanks Mike for all feedback - but with 2048 f/p I would get a high latency, isn't it so (I suppose this relates also to overall hardware)?05:29
holsteinalexandros: does that matter? whats your latency now? like 40ms?05:29
holsteinalexandros: at that point, you cant do software synths live without delay.. or live effects processoing05:30
holsteinprocessing*05:30
holsteinif you are not doing either of those, then who cares what delay you have?05:30
holsteinif it takes 150ms for something to playback when you click "play".. who cares?05:31
alexandroswell, with 128 f/p and 48000 rate and 3 periods I have 8 ms..05:31
holsteinfor me, if i cant get under 10, i dont need anything special05:31
holsteinalexandros: 8ms is pretty drastic05:31
holsteinalexandros: i would try relaxing those settings and test05:31
holsteinalexandros: you can try a realtime kernel.. you can try the other tweaks.. but 8ms is pretty low05:32
holsteini can get 2ms stable, but i dont push it there05:32
holsteini usually run my workstation with about 80ms latency.. to mix and edit05:32
alexandrosholstein: Mike, thanks. I guess it matters if I have to plug my strings and listen to the signal with a bit of latency, isn't it? I think that with 40ms the guitar sound comes with a small delay - please correct me if I am wrong.. :)05:35
holsteinthose are the scanarios above.. live synths and realtime effects05:36
holsteinthere are work arounds05:36
holsteindont track guitar while monitoring through the machine05:37
holsteinuse a different midi unit external to monitor while you are tracking synths05:37
holsteinOR, start tweaking05:37
holsteinthe tweaks you need to do will be specific to your setup05:37
holsteinyou can try a realtime kernel, if you can fine/make one05:38
Len-nbtry all the USB plugs on your machine offten one plug works better than the rest.05:38
Len-nbHyperthreading off05:38
holsteinyeah.. different USB ports can make a big difference05:39
holsteindont use a hub.. unplug other USB hardware, as im sure you already tried05:39
alexandrosthanks guys - I will try all the usb ports, this I can do, it's easy. I do not not use other usb devices than my usb mouce :)...05:41
alexandrosbut how could then I track my guitar and what is how do I turn off hyperthreading?05:42
holsteinalexandros: the USB mouse could be just the issue.. try with *no* other usb hardware plugged05:42
holsteinalexandros: you track the guitar.. just listen to it, live. not from the machine05:43
alexandrosreally???! the usb mouse? :)05:43
Len-nbya05:43
holsteinalexandros: yes.. *any* USB hardware could b causing issues..05:43
Len-nbgenerates interupts with everyt05:43
Len-nblittle move05:43
alexandrosalright! I was not aware of that !05:43
holsteinLen-nb: i had a laptop where the touchpad did it :/05:43
Len-nbThe touch pad may have been USB inside.05:44
holsteinLen-nb: it shared with the USB.. i forget how it looked exactly though05:44
Len-nbholstein, I found if you can get the MB not to select irqs for the USB parts that the Kernel does a better job.05:47
alexandrosholstein: what do you mean by "just listen to it, live. not form the machine"? I use to plug my electric guitar in the usb interface and apply effects with rakarack... could you provide some more details on that please..what should I avoid exactly on this matter?05:47
alexandros:)05:47
holsteinalexandros: righht.. *dont** apply effects05:47
holsteintrack it. *then* apply effects05:48
holsteinOR, tweak you system05:48
Len-nbalexandros, for that yoou prolly want -p12805:48
holsteinim just offering that as a workaround05:48
alexandrosok, thanks guys, I will try out what you mention!05:51
alexandrossorry - my son just woke up, see you later :) cheers!06:01
contrapunctusSay, guys, is there any way I can make my notebook play a sound when the battery reaches a specified level?06:26
contrapunctusAlso, any way to 1. get the battery level (in percent) and 2. switch between normal/presentation modes using only the terminal?06:28
SeveranceHi guys. I've been into the open source movement since early 2006. I've recently started getting into music, and wish to build a recording studio. Do you guys know of any decent recording peripherals that work well with Ubuntu Studio?07:20
SeveranceAlso, how much ram and what CPUs would you recommend?07:21
Guest33894roland hasnt given me any trouble. what doesnt work out of the box, the roland software runs fine in wine07:22
Guest33894at least 2.6 GHz single core or 2 GHz dual core, at least 2 GB RAM07:23
Guest33894well 2.4GHz single if its a high end proc07:24
SeveranceThank you very much, Mr. Guest07:31
SeveranceI'm really liking the V-studio, based on what I've read of Roland's website07:32

Haohmarugot this app which needs to access virtual serial port (/dev/ttyUSB0 actually)15:10
Haohmarubut when i normally run the app - it fails to open it15:10
Haohmaruit works if i run the app via terminal with "sudo"15:11
Haohmarubut it's not convenient, can't i make /dev/ttyUSB0 accessible without sudo stuff?15:11
zequenceHaohmaru: Ok. Sounds like a permission problem15:16
Haohmaruyeah15:17
zequenceHaohmaru: Not sure how you do that, but if you can make /dev/ttyUSB0 accessible by a group (one which you create), then you can just add yourself to that group15:17
zequencePerhaps /lib/udev/rules.d/*15:18
zequenceThis one gives audio group access to firewire devices  /lib/udev/rules.d/60-ffado.rules15:19
Haohmaruwhen i opened the properties of /dev/ttyUSB0 it says the owner is root and there's a group "dialout"15:20
zequence/lib/udev/rules.d/75-tty-description.rules15:20
zequenceHaohmaru: Ok. then just add yourself to dialout15:20
Haohmaruhow? ;]15:20
zequencesudo usermod -a -G dialout $USER15:20
zequenceThere are gui apps for user/group management too15:21
zequenceI guess cause serial was used for modems a long, long time ago15:24
Haohmarubut technically it's USB15:26
Haohmarudamn, still the app can't open the ttyUSB015:28
zequenceHaohmaru: You need to logout and login first15:30
zequenceHaohmaru: Before you do, see what groups you are int15:30
zequenceHaohmaru: In a terminal: groups15:30
Haohmarufor the group changes to tage effect?15:30
zequenceYep15:30
Haohmaruantto@Haohmaru:~$ groups15:31
Haohmaruantto adm cdrom sudo audio dip plugdev lpadmin sambashare15:31
Haohmaruyeah, it's not "updated" yet15:31
zequenceOk, so if you look in /etc/group15:32
zequenceYou have all the groups in that file, and their members15:32
zequenceYou could basically edit it manually15:32
zequenceMake sure you are still member of sudo and whatever :)15:32
Haohmarui already added myself to the dialout group15:32
Haohmarujust didn't know it doesn't take effect instantly ;P~15:33
Haohmaruso imma close down my stuff and reboot15:33
nixnineHey guys, love studio but have a little prob with video conf in that the other person cannot hear me.  Any ideas?20:33
Guest33894do you see the application n its settings if you left click colume indicator -> sound settings -> recording?   is input tab muted / turned down?20:35
Guest33894is the right device listed in the input tab?20:35
nixninewhat tab?21:14
Guest33894in sound settings (volume control), 2 tabs to look at: Output devices, and Input Devices21:41
Guest33894recording & input devices *21:41
sirriffsalotMeh, my terminal does things automatically when I paste it all of a sudden, how do I stop this21:54
Haohmaruwould winXP "see" my ubuntu files?22:36
shai_haludget a program called "explore2fs"23:26
