Now, any audio you play on your Mac will go to BlackHole instead of out the speakers. (Most likely, the only other option you will see will be for the computer’s built-in speakers.) BlackHole as main output. With BlackHole installed, simply open up the System Preferences on your Mac, then click on the Sound pane. For instance, we’ll go back to that hypothetical YouTube video playing in Safari. Once you send audio to BlackHole, you can then route it anywhere else. It shows up as a hardware input and output, fooling your Mac into letting you route audio to it. BlackHole is essentially a virtual audio device. But if you install Existential Audio‘s app BlackHole, you will gain a lot more flexibility. You can choose input and output devices either in System Preferences, or by option-clicking the volume icon in the Mac’s menu bar. then you will hear that from your speakers a fraction of a second later, which the microphone will capture it a fraction of a second later, which you will hear from your speakers…….The Mac packs some powerful built-in audio options, but they only let you route audio out through hardware devices - the built-in speakers, connected headphones, AirPlay speakers, and so on. if you use your speakers to hear the audio, then depending on the speed of your Mac and the volume of your speakers, the mic will capture the sound from the speakers a fraction of a second later. *** for best results when using the aggregate device, you should use headphones to hear the mac's audio. *** you will also need to adjust your MIDI settings depending on which input / output methods (microphone / sound output) that you want to use. Once you do that, (and BEFORE recording) choose “Multi-Output Device" in your menubar "sound options". Then when you choose the recording options, select “Aggregate Device”. Then in the panel that appears on the right, in the Aggregate Device tab, select “BlackHole 2ch” AND “Built-in Microphone” Hit the '+' button in the bottom left corner and select “Create Aggregate Device” If you want to record the internal audio as well as your microphone, it's slightly different. Recording your mic involves the above steps to record the internal audio as well as additional steps to record the mic. I didn't originally include that as the OP didn't ask for that. you cannot control the volume once you are in multi-out mode. before choosing multi-out, set the internal speakers' volume to a comfortable level first. To both hear the speakers and record the audio at the same time, choose "Multi-Output Device". Once you do that, (and BEFORE recording) you can choose "BlackHole 2ch" or "Multi-Output Device" in your menubar "sound options". (and, if you want, any of your other connected devices.) Then in the panel that appears on the right, in the Multi-Output Device tab, select "Built-in Output" AND "BlackHole 2ch". Hit the '+' button in the bottom left corner and select "Create Multi Output Device" Open Audio MIDI Setup: (found in /Applications/Utilities) You will also need to set up a multi-output device in your audio MIDI setup utility to be able to both hear and record the internal audio at the same time. Or for an audio recording, choose "BlackHole 2ch" in the audio recording controls. then you can choose "BlackHole 2ch" in the recording options instead of "Built-in Microphone." i use the free BlackHole Virtual Audio Driver. To record the mac's internal sound with quicktime you need additional software.
