BlackHole VS realtek-uad-harman-mod

I did something similar using BlackHole , with an old Mac, not as fast, but I'm quite happy with the results.

This tip is certainly good, but I prefer to use blackhole in combination with standard quicktime, then compress the video to mp4 without losing quality using handbrake.

Use the built in screen recorder with the cmd + shift + 5 hotkey and then pair it with the free internal audio capture software blackhole or vb-audio cable.

FYI, in the audio industry AI is artificial intelligence, not audio interface. Especially these days when AI is becoming increasingly present in all facets of production, it's probably best to disambiguate. DAC would be more clear (digital to analog converter), or you can just say 'interface'.   If you're on Mac there are several options. My preference is for Blackhole which is open source and free. If you've never used github before, it can be kind of intimidating, but just scroll down and read the downloading/installation instructions and it will walk you through it. There are tons of other ones though like Jack, soundflower, etc.   If you're on PC, your options are somewhat more limited. Cable has come up on a few past searches, but since my PC is used strictly as a virtual instrument server, I don't have personal experience with it.

Or, if you want something even more lightweight, you can record computer audio with the macOS screen recording tool using BlackHole: https://github.com/ExistentialAudio/BlackHole

I found Blackhole and got it configured by creating aggregate device and it basically picks up the audio from the built-in speakers via the built-in mic. I then use QuickTime to do a screen recording and pick the aggregate device as the input.... it works but I'd much rather be able to capture the audio from the Bluetooth headset because I usually work with the laptop closed using two external monitors.

Great app. Blackhole is free tho.

If you're looking to do livestreams, you'll probably want to route the audio from Logic straight into whatever streaming app you're using. Use software like BlackHole or Jack (or something like those) to create a virtual audio device. Read through some manuals or watch a tutorial for nitty gritty, but you'll basically end up routing the output from your track to a virtual audio device, then use that same device as the audio input for your livestream software.   BlackHole is free and open source (don't download an "app" from one of those sketchy macUpdate places). If you've never used github, it can look a little intimidating, but just scroll down and read the installation instructions and they'll walk you through it.
