eviljamesAnyone alive, preferrably someone who knows lvm / raid / ubuntu and what things I should be hunting down if my initramfs is not mounting my root... ?00:18
theotixhello worlds10:37
damo22anyone here?13:17
ailodamo22: What's up?13:18
damo22wondering if anyone has a digidesign mbox213:19
ailoNo, and I was never sure if it's supported or not.13:20
damo22well, soon it will be .. i just submitted a working patch to alsa13:21
ailoOk, so you want to find someone to test it?13:21
damo22i am playing some tunes through it as we speak13:22
damo22just wondering if its a popular device13:22
ailoIt used to be among mac users, I thought.13:23
ailoBut it's been long since I've seen one in action.13:23
damo22i think its quite good for what it is... i havent opened it up to check what brand the preamps are, but it sounds nice in playback @ 24 bit13:24
damo22i know that the mbox 1 had focusrite pres13:25
ailoNot many usb devices with full support, right? How is the generic driver? Isn't it 16 bits only?13:27
damo22i wrote support into the existing usb driver to force the mbox2 into 24 bit mode and actually use it13:28
damo22you can select 44.1k or 48kHz mode at 24bit13:29
damo22and it captures at 24 bit too :) duplex works13:30
ailoNo 96kHz? 16 bit only?13:30
damo22the device doesnt support 96k13:30
ailook13:30
damo22i believe its usb 1.113:30
damo22in my opinion bit depth is more important than 96k sample rate13:31
ailoIt is13:31
ailoI've never used 96kHz for recording myself13:32
damo22i record at 44.1, makes mastering for cds easier, less hassle13:32
damo22but i record in 24 bits13:33
ailoWell, I'm sure 48kHz is best, but I imagine for some processing, even 96kHz can be better.13:33
damo2288.2 is probably better than 96k for audio cd purposes13:33
damo22because resampling is trivial, just skip every second sample13:34
damo22;)13:34
ailoIt makes most difference in the high frequencies of course13:34
ailoBut, most of the time, it doesn't make much of a difference, I think.13:35
damo22yeah, you cant reproduce anything higher than 22.05 on an audio cd13:35
damo22but then, my hearing only goes up to 16k or so13:36
ailoWell, a 10kHz wave is only represented by 4 samples, which is not very much13:36
ailoAnd above that, there usually isn't much, but that would depend on what is being recorded.13:37
damo22true13:37
mbeierlAnyone with linux sound/studio experience ever look into a software interface to replicate an aviom? http://www.aviom.com/Aviom-Products-1/Mixers-1/A-16II-Personal-Mixer14:04
damo22what does that network jack do14:14
damo22some sort of audio transmission over cat5e cable i assume14:20
mbeierlsorry - just notice post.  The device itself takes the output of 16 channels of digital audio data muxed over the ethernet link - coming from a master mixing board.  The Aviom 16 does all the mixing and panning on board and presents the musician with a stereo output.  I'm wondering if anyone's gone under the hood and plugged the ethernet cable into a linux box and tried to demux the audio data right onto a hard drive for later processing or something 14:54
damo22how do you know if its actually using a tcp/ip stack15:05
damo22maybe its a proprietary protocol15:05
mbeierlthat's the problem - I have no idea what stack it's using15:06
crysaztry out wireshark and see if you can dump it15:06
mbeierlah.  good point.15:07
mbeierlI don't actually own one of these - it belongs to the church where I play on the team15:07
mbeierlso I'll have to wait til my next time on the rotation to play around with it a little15:07
damo22seems like a good idea to send audio muxed over cat515:08
mbeierlit is becoming very popular15:08
mbeierlespecially for the whole in-ear-monitor space15:08
damo22but only for those who have a studio with lots of channels15:09
mbeierlsingle cat-5 can easily carry the 16 channels and then a small device at the musician provides the ability to create a personal mix15:09
damo22if it was tcp/ip you could use a simple switch to share the data15:10
mbeierlthe devices do daisy-chain and can be added to without apparent limit15:10
damo22that is the feature of any network15:12
damo22could be rs485 or something or 422 who knows15:12
damo22but what is so good about having a 16 channel mixer at the end of a chain15:18
damo22i would have thought the mix should be preset at the control room15:19
damo22where the monitors are15:20
damo22i can see how it would benefit to have long runs from the control room to the stage made of cat5, then some sort of breakout box with separate preamps to the mics on stage15:22
damo22to shorten the analogue signal path15:23
damo22you still need to pick up vibrations from the air, so mics arent gonna go out of fashion15:25
damo22and thus you need pres15:25
damo22this cat5 stuff is just to cut the cost of wiring long paths to the control room right? and also to shorten the analogue path15:26
mbeierlTo be clear the avioms are used to control the personal monitor mix for in-ear monitors15:43
holsteinmbeierl: theres just an output at each terminal right?15:43
mbeierlthere is also a master mix at the control site, but as this is for live performance, the control booth folks are concentrating on the house mix15:44
mbeierlyes15:44
mbeierlat the end of the cat5 cable is a mix-down box with 16 sliders - like each musician gets his/her own copy of the mix board15:44
holsteinso you dont *have* to use it with the in-ear system15:44
holsteinin theory15:44
mbeierland out of that comes a single L/R channel15:44
mbeierlcorrect15:44
holsteinive been in studios with that kind of rig15:45
holsteinmy favorite was just an analog verion15:45
mbeierlI was thinking for practice I'd like to be able to capture the raw data and do a mix down of my own15:45
holsteinlosts of wiring15:45
holsteinbut, each 'terminal' had a little makie mixer15:45
mbeierlyep - that's the idea15:45
holsteinthe one that was running via cat5 was kinda cheap-ish15:46
mbeierlthey're not cheap $$$ anymore :)15:47
mbeierland it's good, solid construction too15:47
holsteinup at systems2 in NY15:47
holsteinthey had it too15:47
holsteini had a hard time with it though15:47
holsteini mean, its easier for the engineer and all that15:48
holsteinbut, thats kinda what im paying for15:48
holsteinfor someone else to turn the knobs15:48
holsteini had a hard time because the mix was a bit different from the check before one of the takes15:48
holsteinwhen a horn player was added15:48
holsteini had the harmony parts louder than the melody15:48
holsteinand i couldnt really adjust it on the fly15:49
holsteinand we were doing just one take of everything15:49
holsteinmbeierl: you're wanting to take the output from this at church as a multichannel mix?15:50
holsteinto record what you guys are doing?15:50
holsteinif there is just a spare one of the brains, you could do a mix, and record it stereo15:51
mbeierlholstein: yes.15:51
holsteinthen you dont have to do any editing ;)15:51
mbeierlwell... level sets afterwards in a mix down15:51
holsteinright15:51
holsteinthats a lot of wor15:52
holsteink15:52
mbeierlI already am taking the L/R stereo out and using that, but ... I'm always looking to go one further :()15:52
holsteinif you get a good mix on the thing before hand15:52
holsteinthen you just have a ready to go board mix15:52
mbeierlya, that's the problem - it's live15:52
holsteinmbeierl: ideally15:52
holsteinyou would do it at the board15:52
mbeierland I'm playing so it's hard to change my mix on the fly15:52
holsteinwith the inserts or whatever15:52
mbeierlthat would require getting another person at the board :)15:53
holsteinnah15:53
holsteinjust an interface that can capture it15:53
mbeierloh, try15:53
holsteinset it and forget it in theory15:53
mbeierltrue15:53
holsteinas long as you make sure its set at a resonable level15:53
mbeierlyep15:53
holsteinthat likely wont clip15:53
holsteinand it shouldnt in that situation15:54
holsteinwhere the live sound is going to be the limit15:54
mbeierland have it dump all channels to individual audio streams on a HD of sorts?15:54
mbeierlfor a mix down after?15:54
holsteinthats whats going to happen if you work out the other situations15:54
holsteinsituation*15:54
holsteinyou have to capture each channel somewhere15:55
holsteinim assuming via JACK to ardour15:55
holsteinthe end result either way is a recorded track per channel15:55
holsteinfor something like that, i would probably just put up a stereo mic somewhere15:56
holsteinnice live sound15:56
holsteinand less HD space and hassle15:56
mbeierlThere again - it being a chuch service, you don't always get the best sound "through the air"15:57
mbeierlI am reasonable happy capturing my personal mixdown from the Aviom, but I was just curious if there was any known specs for that thing out there15:58
holsteini think the stereo mic mix would be preferable to a board mix15:59
holsteinthat you cant control afterward15:59
holsteina stereo board mix is usually pretty strange15:59
holsteinreally soft drums15:59
holsteinthe opposite of the 'room'15:59
holsteinwhatever needs to be amplified the most is too loud16:00
holsteinyou get to even that out though on your headphone mix terminal a bit16:00
holsteini would go for a multi-channel interface at the board16:01
holsteinBUT, talk about adding an extra person16:01
holsteinyou'll have GB's of mixes stacking up16:01
holsteinto mix down, backup, whatever16:01
holsteindefinitely the ideal scenario for fidelity16:01
holsteinbut, maybe not worth the extra work16:02
mbeierlThe drums are mic'ed quite well and I get a nice crisp sound for them through the aviom...16:09
holsteinright16:09
holsteinin your headphones or whatever though16:10
holsteinyou'll have to compromise what you need to hear for the live recording16:10
mbeierlexactly16:10
holsteinif it were me16:10
mbeierlI tap into the headphone mix and record that16:10
holsteini would not use them at all16:11
holsteinbut i dont use monitors really16:11
holsteini think if its a live performance, and i need a monitor, someone is playing too loud16:11
mbeierlI'm the bassist.  can't get away without them.  the sanctuary that I play in seats 1,200 people16:11
holsteinme too16:11
holsteinyou should be able to16:12
holsteintry and imagine what the monitor mixes must have been like in beethovens era ;)16:13
mbeierlhe didn't use drums16:13
mbeierl:)16:13
holsteinwell, just becuase playing drums and music at the same time has become a problem16:13
mbeierlso if the electric and the bass do not have amps, how am I to hear them without a monitor?16:14
holsteindoesnt mean we should all fight that with louder stage mixes16:14
holsteinthat in turn make the drummer play louder16:14
mbeierlit's not a louder stage mix - it's there's no sound on the stage16:14
mbeierlthat's why I have the in-ears16:14
holsteinguitar without an amp?16:14
holsteinthe guitar players i know16:14
holstein*electric guitar16:14
mbeierlcorrect - guitar without amp.  electric guitar16:15
holsteindepend on the amp for most of the tone they want16:15
mbeierlyes!16:15
holsteinthis sounds like a mess16:15
mbeierlnot anymore.  Thank-you Line 616:15
holsteinand church gigs usually are16:15
mbeierlnot at all16:15
mbeierlit's very clean and crisp16:15
holsteini bet16:15
holsteintotally clean16:15
mbeierlwhy would you want an amp?16:15
holsteinno color at all16:15
mbeierlthat just makes unecessary stage noise :)16:15
holsteinmbeierl: ask *any* guitar player16:15
holsteinmbeierl: i totally see the argument16:16
mbeierlwe have several.16:16
holsteinim just saying, the guy i play with16:16
holsteinwould never be able to do that16:16
mbeierlall of them go without amps now16:16
holsteinwe would mic the cabinet16:16
holsteinand thats the preferred method16:16
holsteini mean, you can get electric drums too16:16
holsteinand the drums wont make any sound on stage16:16
holsteinand why would you not do that?16:17
holsteinbecause the drummer prefers the tone of actual drums16:17
holsteinim not saying get guitar amps16:18
holsteinim just pointing out the differences in this set up with the norm16:18
holsteinAND16:18
holsteinguitar players are right behind drummers usually16:19
holsteinwith the volume before musicality16:19
holsteinmbeierl: is there an extra terminal?16:20
holsteinyou could have one just for the recording16:20
mbeierlwe've got 4 or 5 terminals16:20
mbeierlyes.  but someone would still need to ride the mix to make sure it was good16:20
mbeierlsorry  for the delays - I'm actually at work here... :)16:20
holsteinmbeierl: no worries16:21
mbeierlwhat happens sometimes is that say, one vocalist will get louder part way through a song due to bringing the mic too close...16:22
mbeierlthat gets compensated for in the house mix, but not in the personal mixes16:22
holsteinhmmm16:23
holsteinthat will be in the interface at the board too...16:24
holsteinideally, you'd split each line then16:24
holsteinpre-mixer16:24
holsteineach line and mic16:24
holsteinand like you said16:24
holsteinhave a seperate guy16:24
holsteinto set that mix going to tape16:24
holsteinthen the live sound mixer wont effect those levels16:25
holsteinone of the best sounding local venues here16:25
holsteinthey had great sounds in the room16:25
holsteinand rather than taking a board mix16:25
holsteinor hassling with multitrac16:26
holsteink16:26
mbeierltake the live room...16:26
holsteinthey had 2 sm81's in the room16:26
holsteinand 2 dedicated channels for them16:26
holsteinset and ready to go16:26
holsteinif you have *any* stereo mic16:26
holsteini think that woud be worth trying at least16:27
holsteinsince its SO much easier all around16:27
