This is a video that I threw together to explain a few different aspects of audio routing on MacOS. I’ll show you how to set up Blackhole for recording the system audio on your Mac, and demonstrate the setup I’m using to record my voice, guitar, and system audio in the same video.

Apologies for the somewhat quiet audio!

  1. THANK YOU. I fell like I've been banging my head against this for so long! Blackhole seems to work great but you are right that it is very unintuitive… I can't wait to get this working for my setup.

  2. Super clear explanation, but… for some reason, it won't work for me! Same setup – audio card with the guitar, and Logic Audio with backing tracks. Quicktime audio recording shows wavelengths from both the guitar AND the logic audio backing track, but when i hit record… only the guitar gets recorded!

  3. Hey, I think I‘m getting crazy: Got the same setup like you, guitar via interface+headphone mic+blackhole as input, headphones+blackhole as outputs.

    In QuickTime it works perfectly as demonstrated by you, but the same aggregated input doesn’t work for webcalls, no Zoom, Google Meets, Teams, nothing 😭

    Do you have an idea what the problem could be?

  4. Excellent!! I was having issues with blackhole because I using the same input config as the output. Never thought of using a different config as output.

  5. I'm wanting to take audio out from one app, and send it out both HDMI and the Aux port on a mac, possible with blackhole?

  6. Thank you for this. I teach guitar using Zoom and run through Logic. I couldn't hear myself and my students could. Now I can hear myself (input monitoring). You are the man. Bless you!

  7. None of this worked for me… did one trial test which seemed to have worked, but when I tried recording a Skype video, I couldn't hear the other person in the recording =/

  8. My setup is essentially identical to yours except I'm using Ableton — all my audio tracks are streaming beautifully from Ableton to my Facebook livestream except for my guitar which is really strange. My guitar is just going direct into my Scarlett. Have tried the various and sundry i/o routing options so I'm stumped

  9. I searched for a video that could correctly show me the way to do this is the first one that has really helped me at all THANKS !

  10. Thank you for the time and effort you put into this video! Your recording demonstrations were beyond helpful.

    I'm wondering if you (or anyone) understand the different use-cases for the Blackhole 2ch vs 16ch.

    From my investigation I've yet to find examples or seen anyone "use" the channels so I don't really understand it.

  11. Question, I’m getting a bit lost in the sauce here. My goal that I’m attempting to accomplish is I would like to hear my DAW which is running AmpliTube while running that audio into Discord. How do I accomplish this? I’ve tried a virtual cable, tried playing with the Aggregate device methods, and other audio routing software… any suggestions?

  12. thanks for the video, very informative! i just have one question, how do i choose where i want the audio to go first? for example i want my mic audio from logic pro to go to discord so i can eq my mic and use different fx while in discord, but when i add eq and stuff to my mic in logic it doesnt work in discord, is there anyway to do something like this?

  13. Thank you so much for this very useful video. It shouldn't be so hard yeah? It used to be easier but I think they do this now to help prevent IP violation stuff. Thanks again!

  14. I'm sitting here for an hour now following every step of yout video and still about to give up.
    All I want to do is record audio from my browser into Audacity. I use a Motu M2 audio interface. If I create a multi-output device and check the boxes for M2 and BlackHole and set the audio output to multi-output device I can record audio but I can't adjust the system- and output volume anymore. The volume slider is grayed out. So basically all I can do is record audio into Audacity and that's it. I have to switch audio output devices all the time back and forth between multi-output device and M2. That's not normal I guess.
    Maybe this is a macOS Sonoma problem, I don't know. Maybe you can give me a hint what to do.

  15. I got an extremely difficult setup;

    1. Headphone and mic plugged into Macbook (sometimes apple airplug in stead of Headphone and mic)
    2. Logitec instead of Garageband playing Midi
    3. Youtube playing on macbook
    4. Zoom: for recording everything. All audio from mic, (or airpod mic) and Logic (midi) needs to go to zoom audio so I can hear myself (voice) and logic music.

    I cannot figure this out till now. Even after studying the Blackhole website!

  16. Have you tested these instructions on M1/M2 macs on Sonoma 14.4.1? For some reason, after installing BlackHole, when I restart, it has disappeared from my Audio Devices.

  17. Thank you! This vid saved me quite some trouble. Been trying to figure out sampling beats using blackhole for a minute now. Super duper dopeness. Wicked tips mate. ❤

  18. dude you just me saved hours of figuring out how to correctly use it (im still a bit confused but ill keep coming here as a reference till "as you said" things start to make sense) 
    thank you so much

  19. With Reason 11, the Multi-output Device does not work. I was told by Reason Studios to use the Output use Aggregate-Device.

  20. Thanks so much for taking the time to explain all the I/Os & blackhole. Every other video I've watched doesn't go into WHY and HOW routing works – they just give you the settings with no rationale, which doesn't help with troubleshooting. I'm doing something way different – using a looper as an interface & recording device to OBS – but your video helped me understand what the heck blackhole does!
