FAQ

Why isn't BlackHole showing up in the Applications folder?

BlackHole is an audio interface driver. It only shows up in Audio MIDI Setup, Sound Preferences, or other audio applications.

How can I listen to the audio and use BlackHole at the same time?

Setup a Multi-Output Device

How can I change the volume of a Multi-Output device?

Unfortunately macOS does not support changing the volume of a Multi-Output device but you can set the volume of individual devices in Audio MIDI Setup.

How can I use BlackHole with Audacity in Catalina?

Audacity is not compatible with Catalina. But there might be a work around.

Why is nothing is playing through BlackHole?

Check System Preferences -> Security & Privacy -> Privacy -> Microphone to make sure your digital audio workstation (DAW) has microphone access. Check that the volume is all the way up on BlackHole input and output in Audio Midi Setup. If you are using a multi-output device, due to issues with macOS the Build-in Output must be enabled and listed as the top device in the Multi-Output. https://github.com/ExistentialAudio/BlackHole/wiki/Multi-Output-Device#4-select-output-devices

Where is /Library/Audio/Plug-Ins/HAL/?

Chances are you are looking in ~/Library/ or user/Library/ instead of /Library.

Can I integrate BlackHole into my app?

BlackHole is licensed under GPL-3.0. You can use BlackHole as long as your app is also licensed as GPL-3.0. For all other applications contact me directly at devinroth@existential.audio.
