I am currently setting up my a new M1 Mac for streaming using OBS Studio and was surprised that capturing audio from multiple sources other than the mic required this. It is one of the few things I have found that “just works” on a PC compared to a Mac. I am glad this exists, thank you!

did you try setting up an aggregate device in Audio MIDI Setup? I do a lot of audio work with Macs, and even use blackhole on occasion, but typically something as simple as capturing audio from multiple sources can be done natively with a simple aggregate device.

We use Streamlabs OBS and their support page guides you through BlackHole for setting up on a Mac.

Where would I go to find info on setting this up natively? I've looked before but clearly missed something.

I hope this works for my usecase, as everything I have attempted so far either results in silence or completely mangled audio. All I want on my M1 is to be able to screen record my Zoom calls(full desktop recording) outside of the Zoom application itself. This is because I want to, as a general review tool for myself, be able to refer back to meetings. My memory has gone to hell in recent years. I want to be able to…

I think a lot of people take this approach of recording everything (or at least try to once the idea of recording meetings is available), but you really need to think about whether it’s going to solve the problem you think you have. Having a full recording of everything implies that at some point you have to actually process the content (take notes, etc.), and you’re really just setting yourself up for taking double the amount of time than it would if proper notes were taken in the first place. You seem to be aspiring to use a techie solution to this, but would it really work in practice, and be worth the effort?

Consider that 99.9% of people are able to function pretty well without having to refer back to a full recording of every meeting they’ve ever had. What’s their secret? They just pay attention and take notes the first time through.

Is it possible you have some very specific requirements that no one else does? Maybe, but I’ve landed on the idea that this a really a form of procrastination — where the “paying attention” part of the process is being pushed off until sometime later, and really just makes more work in the long run.

I would be very interested in knowing how to set it up natively as the OBS Studio [instructions][1] that I found recommended using BlackHole along with setting up the aggregate device in Audio MIDI Setup.

No. Recording meetings may be a form of procrastination for you, but recordings can be valuable for a bunch of reasons. Tools like Otter and Gong make it trivial to transcribe and scan meetings, and to jump to associated audio if need be.

Some of us are running those meetings, are focused on the conversation instead of note-taking, and don't have extra staff for note-taking.

I did run into an issue where any WebRTC application like Google Meets would have a lower sample rate and trying to stream in higher sample rate audio would be 2-3 times slower than the original. Really weird but amusing.

You can probably figure out a way to do this with Blackhole but Audio Hijack will for sure if you just want to pay for an easy to set up app.

Fun fact: Apples tries to prevent you from using virtual audio devices like BlackHole with macOS's dictation and speech to text features. I've been unable to get macOS to output the high quality Siri voice to a virtual audio device for recording. It forces a lower quality voice.

Sadly this derailed my plans to use it as a free audio transcripter... (but there's better alternatives and a workarounds)
