Don’t forget to change back the output device under System Preferences > Sound > Output to the built-in or default option after you’ve finished with the screen recording activity.Once you’ve done the screen recording, you’ll see that QuickTime Player is able to not only capture the screen but the internal audio as well.Once the video is ready, click on Record from QuickTime Player toolbar as well as play the video. For test purposes, simply open up a video file or use a YouTube video.Under Microphone, make sure that QuickTime Input, our own aggregate input device, is selected.The QuickTime Player toolbar should appear at the bottom part of the screen.For newer Macs, you can do it by click on the File tab at the top-left corner of the screen, then pick New Screen Recording. Now, you are ready to do a screen recording. From the output list, select QuickTime Output, the same artificial sound device that we’ve just conceived earlier. From the home screen, go to System Preferences -> Sound -> click on the Output tab. Lastly, we need to change the output device under Sound settings.
Furthermore, make sure that “built-in output” is also checked or enabled so you can also hear the sound coming from the computer when you record. Under QuickTime Output, as usual, tick the “BlackHole 16ch” checkbox from the list of audio devices.Rename the option as “QuickTime Output.” Apparent from the name, now, we will try to configure the output of the recording when using QuickTime Player. This time, choose to Create Multi-Output Device. Keep in mind that enabling the built-in microphone may sometimes capture disturbing environmental sounds like vehicle noises and echoes. Additionally, if you wish to also record external sound-such as speech when you are trying to explain something, enable the “built-in microphone” or another audio device that serves as a mic as well.Tick the “BlackHole 16ch” checkbox from the list. Under the newly created QuickTime Input option, there’s a list of audio devices with checkboxes alongside them.For convenience, rename the option to “QuickTime Input” to make things more organized, since we will use the Aggregate Device to configure the sources of the sound (input). Doing that will make another option called “ Aggregate Device” appears on the sidebar.Click the plus icon on the bottom, then select Create Aggregate Device.If BlackHole is installed successfully, you should see a “ BlackHole 16ch” option from the sidebar on the left. This will open up the Audio Devices window.Then, type in “ audio midi setup” on the search bar and tap Enter. Press and hold the Command + Space key on the keyboard to access Spotlight Search.We now need to change some settings on the Audio Midi Setup. Now you have BlackHole ready to use on your Mac.
