[00:53] <joethrun[m]> Hello.  I'm a complete greenhorn looking at the possibility of using Ubuntu Studio for a DAW.  Can you recommend a low latency interface of reasonable quality that will work well with Ubuntu Studio?  I plan on using software synths, guitar amp simulators and recording voice, so I do not want latency to rear its ugly head ever.
[00:55] <Eickmeyer[m]> I'm partial to my Behringer UMC404HD. Hard to go wrong with that or it's siblings.
[01:00] <joethrun[m]> I noticed a fella here in this short thread (Forsland) who is getting 2.67 ms latency:  https://discourse.ardour.org/t/ardour-jack-settings-for-firewire-interface/103261/2                                            Is Firewire something that is worth pursuing?  Or, is it dead?
[01:02] <Eickmeyer[m]> FireWire devices are no longer manufactured. We don’t support them in Ubuntu Studio unless they happen to work with ALSA, which is a crapshoot at best anymore.
[01:05] <joethrun[m]> What kind of round trip latency figures are possible with the Behringer UMC line?  What about the MOTU M4?  or the UR22c?
[01:06] <Eickmeyer[m]> Theoretically, you could get as low as 2ms latency with any USB devices. You can go lower with PCI, but that gets expensive.
[01:06] <joethrun[m]> how expensive?
[01:07] <Eickmeyer[m]> $500 or more.
[01:07] <Eickmeyer[m]> Honestly, unless you’re engineering live audio, you don’t need extremely low latency.
[01:08] <joethrun[m]> well, I would like to avoid hardware monitoring
[01:09] <Eickmeyer[m]> Understood, but the human ear can get used to latency as high as 10-20ms.
[01:10] <joethrun[m]> I would like to stay under 8 ms for large, involved, multitrack projects
[01:11] <Eickmeyer[m]> That’s completely doable with the right PC and interface. Shutting-off Bluetooth and WiFi are musts, and a dedicated graphics card also offloads some of the CPU power.
[01:13] <joethrun[m]> I'm looking at building a computer with a Ryzen 9 3900x, solid state drives, and enough ram, so I should be covered there.  You think USB would be good enough to get the job done?
[01:14] <Eickmeyer[m]> Definitely. I’ve used USB in live environments.
[01:15] <Eickmeyer[m]> Make sure it’s a professional interface though. The run-of-the-mill USB audio cards for <$10 won’t cut it.
[01:16] <joethrun[m]> any experience with the MOTU M2 or M4?  I saw this review, but I'm not sure if he is using it to do multitrack, full duplex studio work:  https://panther.kapsi.fi/posts/2020-02-02_motu_m4
[01:16] <Eickmeyer[m]> Nope. I’ve only used my Behringer and the interface in a Behringer X32/Midas M32.
[01:19] <joethrun[m]> Does Behringer actually have a linux driver?  The brand seems to be popular with linux users and I noticed they have had Ardour bundled with some of their interfaces in the past
[01:20] <joethrun[m]> Are all the class compliant interfaces the same as far as Ubuntu studio is concerned?
[01:20] <Eickmeyer[m]> Behringer uses Linux in their consoles. I just told you that I have used Behringer with my setup.
[01:21] <Eickmeyer[m]> In Linux, much like Mac, there are no drivers mostly. Things just work.
[01:22] <Eickmeyer[m]> All class compliant devices should work natively.
[01:24] <joethrun[m]> can any of the interfaces with dsp be capitalized on in Ubuntu Studio?  In other words, can the onboard DSP be utilized?
[01:26] <Eickmeyer[m]> Do you mean, like, using the DSP as if it were the PC’s DSP?
[01:28] <joethrun[m]> I mean like the DSP onboard the Yamaha UR22c for example.  It is used for mixing, amp simulation, reverb, compression etc.  Mostly for monitor mixing
[01:29] <Eickmeyer[m]> That would be something where the manufacturer would have to supply a driver and software. We don’t support anything outside of the Ubuntu repositories.
[01:31] <joethrun[m]> As someone who is unfamiliar with linux, and wants the most trouble free experience, is their any key advice you can give me for building a linux DAW.  I'm concerned I might be over my head with linux.
[01:32] <joethrun[m]> I can slap syntax into a CLI, but that's about it
[01:32] <Eickmeyer[m]> You have nothing to lose by just trying it. You don’t even have to install it.
[01:33] <joethrun[m]> true true true.  Thank you so much for your valuable time sir
[01:33] <Eickmeyer[m]> Glad to help.
[02:00] <OvenWerks> the xr16/18 can have the dsp controled by linux
[02:00] <OvenWerks> the x32/m32 can as well.
[02:01] <OvenWerks> The A & H QU series can be controled by linux (and the new one but it is 96k only)
[02:01] <OvenWerks> the MOTU avb series can be controled by linux as well
[02:02] <OvenWerks> basically anything that can be controled by OSB, midi or broswer will work.
[04:17] <Goop> I am trying to create a virtual microphone, which takes desktop application sound, along with a real microphone sound, and output them into the virtual microphone, into my web conferencing (Jitsi). This is all on Ubuntu/Linux.
[04:46] <StevenJayCohen> Goop: So you're just trying to loop sound out back to an input source, right?
[04:47] <Goop> Right
[04:47] <Goop> StevenJayCohen, yes. I am trying to combine both application sound and microphone sound with the input source.
[04:48] <StevenJayCohen> So, a simple loopback
