BlackHole with "Aux": 2 Virtual Audio Drivers

This is a fork from ExistentialAudio/BlackHole, which is a modern MacOS virtual audio driver that allows applications to pass audio to other applications with zero additional latency.

The main difference of it is to provide an extra auxiliar audio interface (BlackHole Aux 2ch), which is useful to do some more advanced routing, like you can see in this use-case, where one interface is used to capture the audio, and the other will output it (which was not supported by the original BlackHole project).

Installing

1. Download the zip files BlackHole.driver.zip and BlackHoleAux.driver.zip from the latest release
2. Unzip them and copy the folders BlackHole.driver and BlackHoleAux.driver to /Library/Audio/Plug-Ins/HAL/ (your password may be required)
3. Open the Terminal app and run sudo launchctl kickstart -kp system/com.apple.audio.coreaudiod

You should now see BlackHole 2ch & BlackHole Aux 2ch listed if you open Audio MIDI Setup app.

To uninstall, delete the folders you copied inside /Library/Audio/Plug-Ins/HAL/, run sudo launchctl kickstart -kp system/com.apple.audio.coreaudiod and you shouldn't see them listed anymore.

For details instructions on how to use it, go check the docs in the original project.
