Routing Guitar Pro or YouTube audio

[wt0m]

Hi everyone!

I'm wondering if it is possible to mix the sound from an audio interface and the sound of a Windows application while talking. In other words, I will have 3 audio sources: my guitar (through the audio interface), an app (like Guitar Pro, or YouTube, or Windows Media Player) and my laptop's microphone. The app would allow me to play backing tracks and I would like everyone in the session to hear them.

Also, I'm new to the world of recording and I don't have an audio interface yet, but I'm hesitating between the following : Motu M2/M4, Focusrite Scarlett Solo/2i2/4i4, SSL 2, Steinberg UR24C. Will they all work with Jamulus? Which one would you recommend for recording rock/heavy metal/neoclassical music?

Any help would be greatly appreciated, thanks 😃

I've not tried it myself, but the reccommended way of having more than one thing outputting to a server is to use multiple clients, each using a different channel in your audio device I think. Personally, I would simply plug a mic and my guitar into an external mixing desk though, and just have one client on my machine for simplicity sake. Apps are a bit more tricky, since you can route the output of these via software (eg Voicemeeter or Jack) but there are latency implications to this. So again, I'd just have a laptop running their outputs straight out to a mixing desk into which the guitar and mic were also plugged in.

But I'm sure others would do it differently.

As to audio interfaces, you might have a look over here for some of those: https://jamulus.io/kb/2021/01/05/Jamulus-Sound-Devices.html

Thanks for the quick answer @gilgongo and for your advice!

I didn't think of using multiple clients on the same computer, great idea! However, wouldn't this affect the latency? I guess it will at least use much more bandwidth as each client sends and receives data from the server.
I checked Voicemeeter and Jack, they seem to be the solution for app output routing, do you have an idea about how much latency they can add?

Unfortunately, I don't have a mic so I guess I'll have to use Voicemeeter/Jack. If I understand the idea, the following setup could work, right?
client 1 <- guitar via audio interface
client 2 <- Voicemeeter/Jack <- laptop mic + YT or Guitar Pro sound

Also, thanks for the link with the audio interfaces, I ordered a Motu M4 as it seems to be one of the best in its price range.

Multiple clients won't hit latency unless you have an unusually underpowered machine. Similarly with bandwidth really unless you have a 1Mb/s line or something.

Voicemeteer will add some latency, possibly as much as 20-30ms. Don't know about Jack though.

But yes, that config should work I think. But like I say, I've not tried it myself :-)

Thanks again for your help @gilgongo !
I should receive my Motu in about 2 weeks as it is currently not in stock, I'll tell you if I managed to make everything work 😀
