Hi Ryan, I'm the one of the App Developers for the GoXLR App. I'm going to answer your last question first because it also kind of informs the first question. All the processing other than the playing of samples are done on the physical device it self, This allows for an incredibly low processor load. The app is merely an controller for the device to allow you to make changes to the device, like the color, whats routed where, etc. So if the PC that the GoXLR is connected to freezes, audio would continue to run fine, you would still be able to adjust audio levels and talk to stream. You would lose any audio coming from that computer and you wouldn't be able to fire samples or change the active effect on your voice, ie if you had no effect on you wouldn't be able to add reverb in that moment or if you had reverb on you would not be able to turn it off until the computer came back but the. To answer the second question depends on where your GoXLR is connected. We recommend that it be connected via USB to the Gaming PC and then using the line out on the device and sending it to your Streaming PC, This is because the GoXLR presents itself as multiple audio record sources, Stream (which is mirrored on the Line Out), Voice Chat, and Headphones, on the computer its connected to. The Voice Chat line is intended for sending you mic (and anything you like) to Voice Chat whether that's your Game or Discord. This paired with that the mute buttons functionality can be tweaked on the device to either mute the source (in this case your microphone) to all your record sources. or to each individually. For your case You would set up the Mic mute button to be in the stream only function so when you mute it, it mutes just to your stream and not to your voice chat.
