Audio Mixer
If you really want to go to town with your streaming setup, you can invest in an audio mixer, a dedicated piece of hardware for controlling the various inputs you’re working with, like your microphone and various gaming devices. If you have more modest needs, then simpler audio interfaces can help you keep on top of fewer inputs for less money.
The end result is audio of a higher quality for your streams that’s easier for you to control with a few button presses while you’re broadcasting. The TC Helicon GoXLR Mini ($220) is one excellent example: Specifically aimed at streamers, it gives you control over four audio channels, and comes with its own software utility for simple setup and customization.
