Rode Connect lets you mix up to four USB mics at once - The Verge

Rode’s new app, Rode Connect, lets you record multitrack or mixed stereo audio when plugging up to four USB microphones into your computer.

You can think of the app as a virtual version of Rode’s $599 hardware mixer, the Rodecaster Pro, which allows you to plug in multiple XLR microphones, play audio clips, and record locally.

The Rode Connect does that in an app on your computer with USB mics, which can come in handy for those who do not have an external mixer or professional microphones.

Rode Connect allows you to also add system audio to the mixer — which lets you mix in any sounds playing from your computer or a single application like FaceTime, Skype, Zoom, YouTube, and so on.

If you have a streaming setup in something like OBS, you can select the aggregate sound device that Rode creates as your audio input, and the complete mix from Connect can be used in your stream, without having to play with the finicky OBS audio mixer controls or adding more CPU-intensive plugins.
