How to Record Internal Audio on Mac [Better Pick Within]

Recording internal audio on a Mac can be a bit tricky, as most recording software, including the built-in QuickTime Player, doesn’t offer direct options for capturing internal sound. So how to record internal audio on Mac? Usually, you’ll need to install additional plugins or use your Mac’s microphone to record external sounds, which can be cumbersome. Fortunately, we’re here to introduce a more straightforward alternative to recording your Mac’s internal audio. 

How to Record Internal Audio on Mac with QuickTime Player

QuickTime Player is a powerful multimedia software that comes pre-installed on Mac computers. It is an excellent choice for various multimedia tasks, including video playback, simple editing, and screen recording. One of its notable advantages is its seamless compatibility with the macOS ecosystem, providing a user-friendly experience without the need for extra downloads or complex setups. 

However, QuickTime Player does have limitations when it comes to recording internal audio on Mac. By default, it can only capture external sounds through the microphone, making it unsuitable for recording audio generated by Mac applications or system processes. To overcome this limitation, you need to install a plugin called Soundflower.

Now, let’s go through the steps to enable internal audio recording with QuickTime Player using the Soundflower plugin.

Step 1. Download and Install Soundflower on Mac

Visit the Soundflower GitHub page and download the latest release. 

Step 2. Choose Soundflower as the Audio Output

Once Soundflower is successfully installed, change your audio output device by going to “System Preferences” > “Sound” > “Output,” and select “Soundflower 2ch” (Soundflower 2ch is suitable for recording internal audio, while Soundflower 64ch is for more advanced use).

Step 3. Create a New Aggregate Device

Then you have to create an Aggregate Device that combines Soundflower (for internal audio recording) and your microphone (for external audio recording).

Open the “Audio MIDI Setup” app on your MacBook, create a “Multi-Output Device” by clicking the “+” icon, check both “Built-in Output” and “Soundflower (2ch),” and make it the default by right-clicking “Multi-Output Device” and selecting “Use This Device For Sound Output.” This allows you to capture and hear internal audio simultaneously.

Step 4. Record Internal Audio on Mac

Now, you can record both internal and external audio simultaneously. Open QuickTime Player, select “New Audio Recording,” and click the drop-down menu next to the red button. Under the microphone device options, choose “Aggregate Device.” This allows you to capture both internal and external audio. This method is also applicable when you want to screen record on Mac with audio.

If you prefer to record only internal audio, you can select “Soundflower (2ch)” as the microphone device, but please note that it may not work on some Mac models.
