How to Record System Audio on QuickTime: A Comprehensive Guide


QuickTime, originally developed by Apple, has always been a popular choice for multimedia enthusiasts searching for a reliable application for their audio and video needs. However, one particular aspect of this software can be tricky – recording system audio. In this article, we’ll walk you through a step-by-step guide to record system audio on QuickTime.

Step 1: Download and Install Soundflower

To record system audio on QuickTime, you’ll need to download and install a free third-party tool called Soundflower. This application creates a virtual audio output that routes your computer’s system audio to QuickTime. Visit the official GitHub page at /Soundflower/releases to download the latest version of Soundflower.

Step 2: Configure Audio Output Device

After downloading and installing Soundflower, go to System Preferences > Sound > Output. Choose “Soundflower (2ch)” as your default output device. This will allow your system audio to pass through Soundflower.

Step 3: Set Up QuickTime for Recording

Open QuickTime Player and navigate to File > New Screen Recording (or press Control + Command + N). A recording window will appear.

Before recording, click on the drop-down arrow next to the red record button and choose “Soundflower (2ch)” as your microphone input source. By doing this, you’re telling QuickTime to use your system’s audio as the input source instead of the built-in microphone.

Step 4: Record System Audio and Video

Now your Audio settings are configured correctly in both System Preferences and QuickTime. You can start recording by clicking on the red record button in the Screen Recording window. Select an area or entire screen that you would like to capture, and click “Start Recording” then play the desired system audio.

Step 5: Revert Audio Settings

Once you’re done recording, it’s essential to switch back to your regular audio output device. Go to System Preferences > Sound > Output and change the output device to “Built-in Output” or any other preferred output device.


Recording system audio on QuickTime can seem daunting, but with the help of Soundflower and following these simple steps, you can easily capture any system sound you need. Whether it’s a tutorial or a gameplay session, now you have the power to record high-quality audio and video using QuickTime.
