How To Setup A Microphone FL Studio & OBS

There’s a lot of times you’ll want to record your voice over screen recordings. If you’re making tutorials, or streaming, it’s pretty standard to have a mic. We’ll show you how you can set one up in OBS.

  1. Add a new “Audio Input Capture” by selecting “+” in “Sources” tab.

How To Add A Face Camera FL Studio & OBS

When watching streamers, you’ll notice that a lot of them have a camera set up in the corner. To look more professional and maybe use it as video content in the future, having a face camera might be useful for you.

Before following these steps you’ll need a webcam, or a camera that can be picked up by your computer as an input.

Here’s how you can set up a face camera in OBS:

  1. Create a new Video Capture device, in the “Sources” tab.
  2. Select your camera/webcam from the dropdown list.
  3. Resize your Video Capture, so it’s not in the way of your screen recording.
  4. Start recording with video!

How To Add Different Scenes OBS & FL Studio

In OBS, you can add multiple stream setups which can be useful for flipping between during the stream.

You can also overlay png’s, like your logo, or have a custom box setup for your stream show. This really adds to the professionalism, and can also be very useful when you’re recording tutorials.

For instance, you could have your just your camera on one scene, for scenes where you want to talk to the camera.

Then, you could have another scene with your camera and screen capture, to flip to when producing.

You could also have another camera set up to record your piano, or MIDI controller.

To set up different scenes in OBS follow these steps:

  1. Click the “+” icon on the “Scenes” tab (located bottom left)
  2. Add your Inputs, and Outputs to the “Sources” tab.
  3. To switch between scenes, just click the one you want.

What If I Have The New Mac (Or OS) & OBS Keeps Crashing?

With the newer MacBooks, OBS has a problem with persistent crashes and won’t even open. I know from personal experience, because OBS literally won’t open on my M1 Mac.

This will be fixed with time, but who wants to wait for an update?

To get around this, you’ll need to download something called StreamLabs. It’s completely free, and uses OBS software to stream, but for some reason doesn’t crash like OBS does on M1 Macs.

StreamLabs works exactly like OBS, and is virtually identical. (Personally I think it’s much easier and more user friendly to work with).

For instance, when recording videos, you don’t have to remux them afterward to be compatible in your editing software – StreamLabs automatically converts them to a mov or MP4 format. The interface is also a lot easier to navigate than OBS, and has a more modern look, which I prefer.

To setup StreamLabs, you can follow the same OBS step, by step guide above. Everything is located in the same place, and StreamLabs uses OBS software to stream – it just has a different housing.

Moreover, you can jumpstart your music production process by exploring these top-rated free FL Studio templates.
