macOS Desktop Audio Capture Guide

Capture audio on macOS 13 "Ventura"

When using OBS Studio 28+ on macOS 13 "Ventura" or later, you can capture desktop audio or just the audio coming from a single application.

The audio will automatically be added to the audio mixer. If the source is hidden, the audio will be removed.

To capture all desktop audio, use Display Capture. All audio from all applications will be captured regardless of which display you select.

To capture from just a single application, you can use either Window Capture or Application Capture. If you use Window Capture, audio from the entire application will be captured regardless of which window you select.

If you only wish to capture audio, not show any picture, you can either:

  • Place the macOS Screen Capture Source behind all other sources, or
  • Edit the macOS Screen Capture Source's transformation to set the size to zero width by zero height

Note: you can combine the new macOS Screen Capture Source audio with the other methods below for advanced control over audio.
