| cxmatias | i neet the name of tha programs | 02:28 |
| iatn | I am having noooo luck getting our firewire audio to work under lucid | 09:34 |
| iatn | I've just installed the abog. rt kernel (as the official lucid-rt kernel didn't work at all) under the impression this would be compiled with the old firewire stack but I guess not- how do I check? | 09:35 |
| iatn | Anyone else here have a focusrite pro 26? | 09:36 |
| iatn | I have had it working under DEbian squeeze but on a non-rt kernel and only at 44.1 but I want to use either 48 or 96Khz | 09:37 |
| iatn | bstard thing works straight away under osx :( | 09:38 |
| iatn | OK, its in /boot/config-kernel version and it looks like the bogani rt kernel has both old and new firewire compiled as modules | 09:44 |
| iatn | anyone here relieve me of my firewire misery? | 10:40 |
| iatn | like, should be I be using the old or new fw stack under lucid and how do I properly blacklist the old firewire modules? | 10:41 |
| iatn | (if I should be using the new) | 10:41 |
| Blank__ | hmm | 10:55 |
| Blank__ | i've managed to get firewire working with only a little fuss | 10:55 |
| markie- | I'm trying to install ubuntustudio in vmplayer and after it seems to have installed and configured everything, i just find myself at a commandline prompt, with things like x not even installed. what's going on with that? | 13:56 |
| garym | is there a successor app to replace Audacity? | 15:13 |
| persia | Audacity is still fairly active. What's missing for you? | 15:14 |
| garym | it crashes, it locks solid, it saves a file as a string of zeros, I love it, I forgive it, but I get annoyed | 15:14 |
| persia | Did you file a bundle of bugs? | 15:14 |
| garym | so I wondered why these things didn't get fixed and sometimes that means everyone has jumped ship to some other app | 15:15 |
| garym | eons ago, yes | 15:15 |
| garym | hard to replicate these issues, they are not rare, but sporadic. I just learn to workflow around them, always verify an export wav etc | 15:15 |
| garym | occasionally I forget :( | 15:15 |
| persia | Annoying. The only bugfix that I see that isn't already in lucid is one dealing with multiple ALSA devices. | 15:16 |
| persia | Debian bug #584605 | 15:16 |
| ubottu | Debian bug 584605 in audacity "audacity: segfault with multiple ALSA devices" [Important,Fixed] http://bugs.debian.org/584605 | 15:16 |
| persia | Dunno if there are more pending somewhere, but at least I don't see the patches sitting around somewhere obvious :( | 15:17 |
| garym | I'd reported mine to the developers; it was previous to my adopting ubuntu at ver 7 | 15:17 |
| persia | It's still open on the audacity bug tracker? | 15:18 |
| garym | don't know. so long ago, I gave up following it. | 15:18 |
| garym | and just treat it's reliability like it was a Windows program ;) | 15:18 |
| persia | Well, it's *also* a windows program. | 15:19 |
| persia | But maybe worth checking. | 15:19 |
| garym | haven't found anything better, that supports all the 3rd party effects and as nicely designed, so I just learned to tolerate it. | 15:19 |
| Wiesshund | Is there a channel to ask a general video editing question | 15:20 |
| garym | been editing a field recording today and it has locked up three times in a row, I recover, re-edit, it locks again, so I just thought I'd ask, just in case there was something else people were using instead. | 15:20 |
| persia | Wiesshund, You can ask here, and if someone knows the answer, they will share. I don't know of any general linux-video channels. | 15:20 |
| persia | garym, Some folks use muse, and the "professional" grade app is ardour. Depends on what you need, and what level of complexity you're willing to accept to get it. | 15:21 |
| garym | haven't tried muse. ardour is nice for multitrack, but I don't like it for large wav file massaging. | 15:21 |
| garym | snd is nice too, although the interface is crude | 15:22 |
| persia | snd lets you do everything, as long as you know precisely how :) | 15:22 |
| garym | yes | 15:22 |
| garym | I wish it was command line, although I believe it does support a lot of command line actions making it like the netpbm for sound | 15:22 |
| Wiesshund | When capturing VHS source, to be converted to DVD for television use, during the processing you should leave interleaving correct? | 15:22 |
| garym | never got off my butt to learn how to do that tho. | 15:22 |
| garym | for television use, yes | 15:23 |
| garym | otherwise you lose information | 15:23 |
| Wiesshund | garym ok thanks that is what i was thinking. Would you also reccomend not resizing as well? vhs is being hardware captured @ 704X480 motion jpeg | 15:25 |
| garym | yes, resizing can distort the image with line averaging, although from 704 to 720 isn't a big jump, but I like to keep videos at the original resolution and let the display device sort it out. | 15:26 |
| Wiesshund | thanks, i kept reading stuff saying to shrink vhs captures to 512X384 and 512X480 352X480 etc and it got confusing and made less and less sense | 15:28 |
| garym | 704 is also way more than the resolution of the VHS in the first place | 15:28 |
| garym | vhs is iirc about 470something | 15:28 |
| Blank__ | i thought vhs was around 400 lines at best | 15:29 |
| garym | so you've got oversampling going on, that should capture the original experience no matter what you do with scaling | 15:29 |
| garym | it also depends on your display gear, you may want to do some short tests and view them | 15:29 |
| Blank__ | Wiesshund, unless you've got an excellent software de-interlacer, best leave that job for the receiving end | 15:29 |
| garym | Blank__, I'm not totally sure, maybe I'm thinking of Beta? I know vhs is better than broadcast but not by much | 15:30 |
| garym | wikipedia will know :) | 15:30 |
| Wiesshund | 704 is the hardware device's native resolution i guess youd say | 15:30 |
| garym | yes | 15:30 |
| Blank__ | Wiesshund, i'd recommend cropping, if there are any parts of the screen that are garbled, such is life with vhs | 15:30 |
| Blank__ | they will only waste data | 15:31 |
| garym | maybe I was thinking of superVCD? video formats drive me nuts | 15:31 |
| Wiesshund | BLank so far aside from the small line at the bottom otherwise known as macrovision, no garbling yet on the raw captures | 15:31 |
| * garym has to go back to editing his recording and thanks everyone for their advice | 15:31 | |
| Blank__ | the line at the bottom isn't macrovision, is it? i thought it was merely due to calibration | 15:32 |
| Blank__ | or miscalibration | 15:32 |
| Wiesshund | Im trying to save the kids old vhs movies for thier kids, mostly disney movies. | 15:32 |
| Blank__ | but yeah, i tend to replace that with black, because that means the mpeg encoder will put more data into the actual frame, where it counts | 15:33 |
| Blank__ | hmm... now i think about it, vhs is actually something closer to 320 lines | 15:34 |
| Blank__ | 340? | 15:34 |
| Wiesshund | Blank__ no the line is not present on vhs playback, only seen after capture, its the noise injection macrovision does. I had a hell of a time coming up with a capture machine that didnt shut off when it saw macrovision | 15:34 |
| Blank__ | ah, so it's not what i think it is... i've read up on how macrovision works | 15:34 |
| Blank__ | something like lines just outside the frame that are unusually intense, and cause most screens to lose sync | 15:35 |
| Blank__ | or more accurately, if run through anything but a tv, cause sync problems | 15:35 |
| Blank__ | you can buy processors that remove it | 15:36 |
| Wiesshund | think its 352X480 vhs up to 400 for svhs but its interleaved and pc resolutions are not | 15:36 |
| Wiesshund | Well the game plan is simply to get the aging vhs tapes, to dvd, for tv viewing | 15:36 |
| Wiesshund | and not make them look any worse in the process | 15:37 |
| Blank__ | oh... vhs are actually closer to 250 lines | 15:37 |
| Blank__ | which is pretty dismal | 15:37 |
| Blank__ | but it's interleaved, true | 15:37 |
| Wiesshund | its kind of confusing though, cause if you take something at say 384X240 on a pc and blow it up to full screen, it looks like ass | 15:38 |
| prep | breaker breaker 7-1-9 anybody got their ears on? | 15:38 |
| Blank__ | In modern-day digital terminology, VHS is roughly equivalent to 333x480 pixels luma and 40x480 chroma resolutions. | 15:39 |
| Wiesshund | odd isnt it? you can display 333X480 at full screen on a 27" tv and it looks great, then try it ful screen on a 24" pc monitor and it looks like pixelated ass | 15:40 |
| Blank__ | probably poor upsampling on pc | 15:41 |
| Blank__ | i'd go as far to say that analog upsampling looks a lot better than digital | 15:41 |
| Wiesshund | yea, guess the pc wasnt exactly meant to try displaying vhs data | 15:42 |
| Blank__ | :p | 15:44 |
| Blank__ | well i'm off to bed | 15:44 |
| Blank__ | good luck with the vhs capturing, i've been trying to do the same for our family videos | 15:44 |
| Blank__ | unfortunately i've stuck with using windows and virtualdub because i could never find what i needed in linux | 15:44 |
| Wiesshund | im kin of in the same boat | 15:47 |
| Blank__ | there's nothing really available for analog capture | 15:47 |
| Blank__ | at least, nothing that i can use as simply as virtualdub in capture mode :( | 15:48 |
| Wiesshund | For the capture box, i had to find something that was macrovision unaware. which wound up being an old matrox rainbow runner studio mjpeg hardware capture board | 15:48 |
| Blank__ | for dv cameras there certainly did | 15:48 |
| Blank__ | certainly are* | 15:48 |
| Blank__ | i've been using a tv tuner for my captures | 15:48 |
| Wiesshund | you doing mostly home video? | 15:49 |
| Blank__ | ideally i'd be running s-video from the video camera to the card but we didn't end up getting one with s-video, only composite | 15:49 |
| Blank__ | yeah, all home videos | 15:49 |
| Blank__ | from video8 | 15:49 |
| Wiesshund | lucky you, no macrovision to hassel with | 15:49 |
| Blank__ | true | 15:49 |
| Blank__ | even if there were i'd look at getting a video stabiliser | 15:49 |
| Wiesshund | i understand why they used it, but in retrospect making a degradable media non backupable is dumb | 15:50 |
| prep | Need assistance with ppa | 15:52 |
| Wiesshund | yea i lucked out still having the old rainbow runner, it does true hardware mjpeg and has some onboard video stabilization. down side is to use it i an forced to run win98 on the capture box, as that was the last OS that card ran in | 15:52 |
| Wiesshund | So im processing the raw captures on my normal pc where i dont have to wait 5 years hehe | 15:53 |
| Blank__ | yeah | 15:54 |
| Blank__ | well i'm off | 15:54 |
| Blank__ | probably catch you later :p | 15:54 |
| Wiesshund | ok cya later | 15:54 |
| ManDay | Does anyone know an LADSPA plugin which can do multiband fitlering like an equalizer just with less load on the CPU? | 19:02 |
| holstein | ManDay: you could route the audio through the plugin | 19:03 |
| holstein | and record a new track | 19:03 |
| holstein | then it wouldnt be using any processing power at mixdown | 19:04 |
| holstein | you would just need to re-record that track each time you need to tweak th EQ | 19:04 |
| holstein | but usually that is something you set and forget | 19:04 |
| holstein | is this something your doing in realtime? | 19:07 |
| * holstein uses rakarrack for whatever realtime processing i can get away with | 19:08 | |
| holstein | it seems to run rather light weight | 19:08 |
| ManDay | erm | 19:23 |
| ManDay | thanks but this is for live playback | 19:23 |
| holstein | ManDay: try rakarrack then | 19:28 |
| ManDay | is that ladspa? | 19:28 |
| holstein | nah | 19:28 |
| holstein | its standalone | 19:28 |
| ManDay | i try to do that with pulse | 19:28 |
| holstein | pulse? | 19:29 |
| holstein | JACK is the way to go | 19:29 |
| ManDay_ | | irc: disconnected from server | 19:29 |
| ManDay_ | | irc: disconnected from server | 19:29 |
| holstein | hmmm | 19:29 |
| ManDay_ | jack is a little overhead in my case | 19:29 |
| ManDay_ | im just a simple minded user | 19:29 |
| ManDay_ | no need for fancy plugging | 19:29 |
| holstein | well, it does more than that | 19:29 |
| ManDay_ | lol | 19:29 |
| holstein | its the sound server for your needs | 19:29 |
| ManDay_ | that doesnt give me any more reason | 19:30 |
| holstein | doing realtime effects processing in pulse wont work | 19:30 |
| ManDay_ | im fine with pulse, i just want to equalize my stuff without the CPU load | 19:30 |
| ManDay_ | a high pass would already do | 19:30 |
| holstein | your 'stuff' ? | 19:30 |
| holstein | like guitar in? | 19:30 |
| ManDay_ | music | 19:30 |
| holstein | OH | 19:30 |
| ManDay_ | no, im a simple end produc user | 19:30 |
| holstein | yeah, just use one of the EQ's in VLC or something | 19:30 |
| holstein | something in a player | 19:30 |
| ManDay_ | nah thats so cumbersome | 19:31 |
| ManDay_ | there are so many ladspa plugins, one must offer that | 19:31 |
| holstein | sure | 19:31 |
| holstein | but then your adding things | 19:31 |
| holstein | if you use VLC | 19:31 |
| holstein | its already lightweight | 19:31 |
| ManDay_ | I think if I ran my output through VLC id get more overhead than with a Multiband eq | 19:31 |
| holstein | and its got that capacity right there | 19:31 |
| ManDay_ | holstein: you mean using VLC on its own? | 19:32 |
| ManDay_ | i wont leave mpd, i love it | 19:32 |
| holstein | ManDay: why not just edit the audio in audacity or something? | 19:32 |
| ManDay_ | it needs to be system wide | 19:32 |
| ManDay_ | filtering | 19:32 |
| holstein | yeah, just edit the track | 19:32 |
| ManDay_ | besides, i dont want it to be persistant | 19:32 |
| holstein | hmmm | 19:32 |
| ManDay_ | that could do irreversible damage | 19:32 |
| holstein | well, there not really a lighter-weight way to do it | 19:33 |
| holstein | maybe an MPD plugin? | 19:33 |
| ManDay_ | im pretty sure that there are no plugins (like that) | 19:33 |
| ManDay_ | actualyl ive never heard of an MPD plugin | 19:33 |
| ManDay_ | but there is most likely no equalizer one | 19:33 |
| ManDay_ | thats why on their website they suggest jack | 19:34 |
| ManDay_ | if one needs an eq. but pulse is a little more suitable in my case, if just that ladspa plugin... | 19:34 |
| ManDay_ | ok thanks tho | 19:34 |
| holstein | ManDay_: is this the one your using? | 19:34 |
| holstein | http://www.thedigitalmachine.net/alsaequal.html | 19:34 |
| ManDay_ | im not using anything right now | 19:39 |
| ManDay_ | i vent seen that eq tho | 19:39 |
| ManDay_ | thanks! | 19:39 |
| holstein | :) | 19:41 |
| ManDay_ | hm | 19:42 |
| ManDay_ | so that uses ladspa too | 19:43 |
| ManDay_ | haha, how funny | 19:43 |
| ManDay_ | pulse can use the same plugin, with the only difference that it cannot do runtime adjustments to the plugins inputs | 19:43 |
| holstein | ManDay_: have you read http://ubuntuforums.org/showthread.php?t=789578 | 19:48 |
| holstein | i would think the karmic info would be mostly relevant to lucid | 19:51 |
| === ManDay_ is now known as ManDay | ||
| ManDay | im doing this for a non ubuntu pc, i just came here because i remembered that you guy are expert on the field :) | 20:18 |
| ManDay | hope you dont mind | 20:18 |
| holstein | ManDay: fine with me :) | 20:19 |
| holstein | there is also #opensourcemusicians | 20:19 |
| ManDay | i took the alsa mixer now, i have yet to plug it in but it looks good | 20:20 |
| ManDay | thanks a lot holstein you helped me a lot | 20:20 |
| ManDay | :) | 20:20 |
| Davidmp | Holstein i need some advice | 20:24 |
| Davidmp | i need a new stopmotion program because stopmotion doesn't work for me do you know of any good programs that could replace that? | 20:24 |
| * holstein not sure Davidmp | 20:41 | |
| Davidmp | hm | 20:42 |
| * holstein running out for some food | 20:42 | |
| Davidmp | mkay | 20:42 |
| holstein | i'll poke around a bit when i get back though :) | 20:42 |
