Setting Up Your Audio in OBS
Nearly there! Select the “Audio” option and select your default desktop and microphone device (if you have one). OBS allows you to put a delay on your voice and edit any gain or audio boosts you require. Selecting “Microphone Noise Gate” gives more control over how loud different audio sources are, and is worth experimenting with to perfect your stream quality. If you do know a bit about streaming, and OBS, there is also an “Advanced” area to really fine tune specific areas, however this guide will not be covering that.
Now you will be able to stream directly to Twitch. Just head back to the main screen, simply select “Start Streaming”, and you’ll be ready to go! It’s important to remember that streaming takes a lot of trial and error, and perfecting the quality will come down to changing settings accordingly to fit your own capabilities.
