[12:37] Most of the apps you'll "need" for multimedia production should already be installed. However there should be a GUI app source in there. I switched to KDE so I'm not sure what it's called in xfce anymore. Search your app menu for "application" as it's not really a "store". Developers of your favorite app often and gladely take your donations through their own channels, [12:37] though. [12:41] Yesterday I made a live DJ-set for a virtual graduation party, and I'm happy to report that despite mixxx broadcasting being currently broken, BUTT integrated perfectly. [12:43] Weird thing to do. But very fun. Basically socialising happened in a video conf app. And sound went over icecast2. (Sound of most video conf apps is decent enough for voice but definitely not for music. And if someone takes the word, it will cut the djs input) [19:23] Hey, I'm working on a small script that disables stuff I don't need while recording. See here, underExample script to disable resource-intensive daemons, services and processes, https://wiki.linuxaudio.org/wiki/system_configuration (also pasted the important parts here https://pastebin.com/rGUKbe2W ) and it looks like my processes are different. Can you point me towards something that'll help me find the ubuntu [19:23] processes I need to set here? [19:25] specifically, my NIC and wireless drivers appear to be different. Also not sure about the video/webcam drivers and whatever a parallel port is. The bluetooth and cups entries seem to work fine. [19:26] I would LOVE an example script from someone running ubuntustudio where they disable unnessary things when the lowlatency kernal is running. [19:27] wangdoodle: You don't need ANY of that with Ubuntu Studio or by using Ubuntu Studio installer. That entire article doesn't apply because we've already done it for the user. [19:28] Moreover, we don't support compiling kernels, so you're on your own there. [19:28] !rt | wangdoodle: Moreover, heed this warning [19:28] wangdoodle: Moreover, heed this warning: The RT kernel is the Linux kernel with special realtime patches applied. It is not available in Ubuntu. See also !lowlatency and https://help.ubuntu.com/community/UbuntuStudio/RealTimeKernel [19:29] Read that article why RT kernels are BAD. [19:29] !ubuntustudio-installer | wangdoodle [19:29] wangdoodle: Ubuntu Studio Installer is an app that can be used to add Ubuntu Studio's benefits to an existing Ubuntu (or official flavor) installation, or add additional packages. For more info, see https://ubuntustudio.org/ubuntu-studio-installer/ [19:30] TL;DR: I am not going to support helping someone do something that I (and others) have already done for them. [19:31] Funny. I did notice that some of these optimizations were already done in ububntu studio, which I have installed, along with the lowlatency kernel, not realtime. [19:32] But, things like networking and printer stuff and plex and apache need to be stopped, it seems. [19:32] Ubuntustudio doesn't do that does it? [19:34] No, that's overkill. At most, wifi and bluetooth. Ubuntu Studio's goal is to be a full-fledged creativity workstation, not an audio appliance. [19:35] Audio is simply one of our areas, but that's a part, not the whole picture. [19:36] I noticed that I could run Ardour with better settings when plex wasn't installed. I also think apache got installed and is running. Then when I get working I'll have Java and Virtualbox going so. I think I need a way to disable all this when recording audio. [19:37] We don't install apache by default, nor virtualbox, So, disabling any of that is on you if you installed it. [19:38] OMG, of course. But, if I can't ask how to disable the usual stuff, I can't adapt it to disable what I need to. [19:39] Someone at the kubuntu channel suggested I ask you guys since you may have similar needs. But, I get attitude. [19:39] That's a discussion for #ubuntu. Apache, virtualbox, and what-not is completely out of our scope. [19:40] What you need to do is disable services, and we simply are not experts in web servers and things like that here. [19:41] I saw the discussion, and all you mentioned there was realtime processes. You didn't mention apache or anything like that there. [19:42] wangdoodle: I'm a volunteer, and while I am in charge of Ubuntu Studio, I'm not an expert at everything. [19:42] I guess I wasn't here to ask an ubuntustudio employee about it, but more of a daily user. Sorry, I'll look elsewhere. (I mentioned the part about needing to ask how to do the usual disables to adapt them to my needs. [19:42] There's no such thing as an Ubuntu Studio employee. Everyone on the project is volunteer. [19:43] Nobody is getting paid to do this. [19:43] volunteers should never have a bad attitude. you must have it rough. my heart goes out to you. best wishes [19:43] We DO have to draw the line on what we support. I don't have a bad attiude, and I"m sorry you perceive it as such. I'm just giving you facts. [21:20] Eickmeyer: I don't know how, but pulseaudio or someone messing around with gain/volume-settings done messed up. Just tried a live-version of 19.10, and it's back to normal. If I crank the audio-level up to 120% I get very much the same kind of distorted noise that I get on 100% in Ubuntu Studio 20.04 [21:21] ubuntu-studio: I'm willing to bet it's a change in the xfce4 pulseaudio plugin. Just run it at 80% and it should be rougly close to 100%. Shouldn't affect your ardour mix. [21:22] And... interesting nickname. :P [21:22] Eickmeyer: it bothers me, so I'm reverting back to 19.10 for now. Haha yeah [21:23] That'll tell you I'm surfing on a live-usb [21:23] Just FYI, it loses support in July. The volume issue is unlikely to get resolved, and there's no configuration we've done on our end. [21:24] 20.10 is a different desktop environment, so the issue might be resolved that way. [21:24] Eickmeyer: once again thanks for all your help.. but I'll be very surprised if no one else reports this as a problem in the future. Yeah I know, I didn't really need to upgrade in the first place, I still know people who use ubuntu 10 lol [21:24] Reboot,, brb [21:33] TIL Behringer X-series mixers and the Allen & Heath iLive series mixers use RT Linux kernels. [21:33] AppAraat[m]: I am not surprised [21:33] A & H mixers also use integer math [21:34] (and multiple processors depending on the number of channels/effects required [21:34] even the QU 32 has 4 separate processors. [21:35] There are a numnber of people who do not think the iLive sounds as good as the older A & H alanog mixers [21:36] I suspect that using Ints for the math has something to do with that, even comparing 48 to 64 bit int to 32 bit floats. [21:36] I would take the 32 bit float every time. [21:37] *analog [21:38] huh, I thought all decent digital mixers were either 24bit or 32bit [21:39] 24 bit ADC but 48 to 64 bit internal for math then back to 24 for output. [21:39] with int math you have to add 1 bit for every channel you add to the mix [21:40] AppAraat[m]: actually, my thought would be 24 bit ADC convert to 32 bit float for math, output 16 bit... [21:41] but it would never sell without 24 bit output too :) [21:41] why would you need to have higher bitrate internally if you're recording 24bit ? [21:41] Is it because every channel is recorded at 24bit? [21:42] (and is thus required for digital summing) [21:42] if two channels are at a digital 1 (full scale) at a the point they are mixed together, that eqals 2 [21:42] which needs one more bit [21:43] add another channel (maybe two more channels?) add another bit [21:43] ah right, makes sense [21:43] with 32 bit float (which is really the same resolution as 24 bit int) that is not needed [21:44] the exponant will always take care of that [21:46] the reality is that even 16 bit is over kill for reproducing anything we can hear, so that is the greatest we need to use for playback but for recording it is nice to be able to record 20 or more dB down from FS to ensure no clipping while still having 16bit resolution. [21:48] My understanding is that the X32 uses 32 bit float internally [22:09]

A reinstall of my original ISO seems to have got rid of the over runs, might be an update that screws it up ! [22:12] goody [22:13] I have not noticed anything like that here... but I don't have wifi, BT or a USB audio device... [22:16] shas-0[m]: every time you restart may make a difference, but an update may too in how irqs are allocated as in which order [22:17] I found telling my bios _not_ to assign irqs and let the kernel do that instead seemed to result in better choices [22:36] The main thing I have found worth turning off is Cron. Cron is run at a low priority, but... if part of what it runs is apt update, there are diskwrites, and network transfers that are atomic.
