| wonko | OvenWerks: as long as the devices stay plugged into the same ports they *should* always scan in the same order. That's a pretty terrible way to live though so something based on serial number is probably best. | 01:00 |
|---|---|---|
| OvenWerks | wonko: Yeah, it is easy enough to find if that is the same as usbid | 02:57 |
| OvenWerks | wonko: I am just wondering if a device that uses the same chip and the serial is not set ends up with the same serial number. | 02:58 |
| OvenWerks | or if that has to be setup outside the chip for it to work. | 02:59 |
| wonko | I've been kicked off my computer by the 4 year old but I can poke around later | 02:59 |
| OvenWerks | wonko: just looking at the PCM2912A from TI (an all in one audio to USB to audio chip... mic in phones out) | 03:17 |
| OvenWerks | wonko: the data sheet says "Serialnumber - Not supported" | 03:18 |
| OvenWerks | So at least in some cases, two devices the same can not be separated by SN | 03:19 |
| OvenWerks | There is no provision in this chip for setting anything from outside the chip either. | 03:19 |
| wonko | yeah, running usb-devices shows how random and useless that is. The KA6 gives a serial (but NI cares about that) whereas other devices either give no serial or give some totally BS serial, like this camera. I don't think SerialNumber=Ucamera002 is the read serial number. :) | 03:48 |
| OvenWerks | wonko, I don't care if it is real... so long as it is unique | 03:51 |
| OvenWerks | it may be in the end that we worry more about the physical usb port being used | 03:52 |
| OvenWerks | wonko: as happens I do have two devices that seem to have the same chip from c-media but still have different manufature id and product id... but then c-media's chips all seem to support wriable man/prod ids. | 03:54 |
| OvenWerks | wonko: at least one other person seems to have come across the same problem and has a script that deals with "same vendor, product and serial id" | 03:57 |
| OvenWerks | they look at: /devices/pci0000:00/0000:00:1d.0/usb2/* stuff | 03:58 |
| OvenWerks | Souler: have you tried running ffado-mixer? | 04:59 |
| OvenWerks | does it say if you have internal of external clock? | 05:00 |
| OvenWerks | wonko: I have three USB audio devices plugged in, none of them have a serial numb er other than 0. | 05:48 |
| OvenWerks | wonko: so... I think I will use the name (minus any _1 or other number), the USB man/prod and the usbbus (bus/unit I think) | 05:51 |
| OvenWerks | It is interesting that my two c-medis devices say they have manufacture=Intel but they and the other USB device all show up as "Device" so I suspect they are all the same chip but flashed with different manufactures :P | 05:53 |
| b7jl | hi, i'm thinking about installing ubuntu studio, but I'm worried that the learning curve on the audio tools will be too steep | 06:04 |
| b7jl | my audio skills are very analog | 06:04 |
| b7jl | any advice for me on this? | 06:05 |
| OvenWerks | Ardour generally follows analong mixing style | 06:05 |
| * OvenWerks can't spell very well. | 06:05 | |
| b7jl | sounds good... | 06:05 |
| OvenWerks | try looking at some of the screen shots at ardour.org | 06:06 |
| b7jl | i'm fine with ubuntu, some scripting, etc | 06:06 |
| OvenWerks | but really any DAW has some learning curve. | 06:06 |
| b7jl | yeah some of the screenshots I've seen seem intense | 06:07 |
| OvenWerks | you should not need much scripting | 06:07 |
| * b7jl goes to look at ardour.org | 06:08 | |
| OvenWerks | for many things you can pretty much ignore the edit screen and deal with the mixer screen | 06:08 |
| * b7jl returns | 06:09 | |
| b7jl | I've just gotta dive in, I think | 06:10 |
| OvenWerks | pretty much yes | 06:13 |
| b7jl | any hardware gotchas I should be aware of? can I basically expect it to run on any machine that meets the system requirements? | 06:34 |
| OvenWerks | Assuming you are using USB audio... it may take some fiddling. In particular try it in each USB port on the computer to see which is most stable | 06:36 |
| b7jl | ok | 06:36 |
| OvenWerks | system requirements are not really a minimum kind of a deal. | 06:37 |
| b7jl | yeah | 06:37 |
| OvenWerks | When people in the computer world talk performance, they mean throughput | 06:37 |
| b7jl | I can get my hands on a nice newish dell that I am planning to use | 06:37 |
| OvenWerks | for audio we want the ability to meat deadlines | 06:38 |
| OvenWerks | I have been using an i5 (four cores no hyperthread) with no problem | 06:38 |
| b7jl | good to know | 06:41 |
| OvenWerks | one of the big things is to get the cpu to run at a steady speed. not slower when idle and speed up for heavy use. Audio tends to glitch at the slow down point and actually runs better at the lowest speed than with ondemand, but performance mode (always full speed) is best | 06:42 |
| OvenWerks | studio-controls allows setting this. | 06:43 |
| b7jl | hmmm, I have lots to learn | 06:43 |
| b7jl | this is good intel though | 06:43 |
| OvenWerks | most things have been well tested with intel | 06:44 |
| b7jl | haha I meant intel in the sense of intelligence -- good info i mean | 06:44 |
| OvenWerks | Intel has people who add bits to the linux kernel to make sure Intel cpus work well with Linux | 06:44 |
| OvenWerks | :) | 06:44 |
| OvenWerks | sorry | 06:44 |
| b7jl | my bad | 06:45 |
| OvenWerks | I am used to it, there are people on here from around the world | 06:45 |
| b7jl | yep | 06:45 |
| OvenWerks | My wife is also from half way around the world | 06:45 |
| OvenWerks | another thing to remember is that harrisonconsols MixBus is based on Ardour and so their tutolials can be useful https://harrisonconsoles.com/ | 06:49 |
| OvenWerks | tutorials | 06:49 |
| * b7jl goes to take a look at | 06:50 | |
| OvenWerks | harrisonconsols trion digital consols do use AMD computers for audio processing so I know it is possible with them as well | 06:52 |
| b7jl | what tool should I learn first? there seem to be a lot of complementary components, but I should probably start with the basics | 06:55 |
| b7jl | ardour? | 06:55 |
| OvenWerks | If you are used to analog signal flows yes. | 06:56 |
| b7jl | ok | 06:56 |
| OvenWerks | qtractor is a tracker, so is lmms. | 06:56 |
| b7jl | just knowing where to start is a big help | 06:57 |
| b7jl | so thank you for this | 06:57 |
| OvenWerks | qtractor can record audio just fine as well, but lmms can't | 06:57 |
| OvenWerks | https://www.youtube.com/watch?v=bfTAKv4htDE is an Ardour intro that may help. Unfa does a lot of stuff with Ardour but he is more of a sound designer than recordist | 06:58 |
| b7jl | I mean, I'll want to record my guitar, etc, but I'm also very excited about computationally generated sounds | 06:59 |
| OvenWerks | like take the sound of opening a can of evaporated milk and make a whole song of it | 06:59 |
| b7jl | that video is long; i'll watch it later. it's been bookmarked | 07:00 |
| OvenWerks | no surprise :) unfa's videos tend towards long | 07:00 |
| OvenWerks | https://www.youtube.com/channel/UCqeg5vkTkH-DYxmOO9FJOHA | 07:01 |
| OvenWerks | these are a bit shorter. | 07:01 |
| b7jl | i saw a conference talk by a guy who trained a machine learning model on Bach and had it make its own Bach. it was neat | 07:01 |
| b7jl | ok, also bookmarked | 07:02 |
| OvenWerks | https://www.youtube.com/user/HarrisonConsoles/videos | 07:02 |
| OvenWerks | are also short... probably skip the ones on plugins though unless you want to buy them. | 07:03 |
| OvenWerks | mixbus has eq in each channel, Ardour does not. That is the big difference. Ardour does comes with quite a good eq plugin included | 07:04 |
| b7jl | ok, I should go, but thanks for all of your help! | 07:09 |
| rgh | I wanna add that in most cases everything just works. | 07:25 |
| rgh | Oh. They're gone 🙃 | 07:25 |
| OvenWerks | rgh: now you are here... | 07:32 |
| OvenWerks | I want to ask in your more than one USB situation, do you thnk it would be ok to say the same device must always be plugged into the same socket? A lot of devices have no ser. no. | 07:33 |
| * OvenWerks wanders off to take his dog out one last time | 07:34 | |
| rgh | OvenWerks: sounds hacky but if that is the only thing that works 🤷♂️ | 08:21 |
| rgh | Let me say again that it's not for my own purposes but someone in the KX studio chat asked about it. | 08:22 |
| OvenWerks | rgh: yeah, but it does fall right in "controls should fix this" territory | 17:19 |
| OvenWerks | rgh: it just tells me how far audio device quality has fallen. I think the firewire boxes are much better. | 17:20 |
| OvenWerks | I had a firewire box sent to me so I could figure out fw in controls and I have to say it is much better than any USB box I have played with. | 17:22 |
| OvenWerks | (the cost of shipping and getting a FW card and cable were almost as much as a low end usb box) | 17:23 |
| OvenWerks | but I can get lower latency than is possible with USB (USB min is 2ms for stable opperation 32/3) | 17:27 |
| Voidnaut | Hello! I am trying to setup my gear with JACK. I have an external audio interface (Behringer X1204 with some synths hooked up), I'm using BitWig as a DAW and VCVRack as another instrument. It seems I can either route my audio interface or VCV to BitWig; But not both simultaneously. I'm pretty new to linux but I believe I either need to create a | 19:01 |
| Voidnaut | pseudo-device by merging my internal and external audio devices or use JACK2. Is that correct? Which way is preferable? Thanks in advance! :) | 19:01 |
| Voidnaut | I actually got it! Apparently I just needed to patch everything through 'system' and reconfigure bitwigs audio! I LOVE ubuntustudio! <3 | 19:23 |
| jasonerid[m] | hi | 21:37 |
| jasonerid[m] | is there someone here? | 21:37 |
| jasonerid[m] | i need help | 21:39 |
| Jesse-David | Sorry Ovenworks, had some weird power outages this weekend. Anyways it seems to be working somewhat normal. Though on startups it seems to be having issues with executing autojack. Going to try a few things today and let you know how it works. Otherwise thanks for the help! | 22:01 |
