Pulltube works so well that it was worth the cost of a standard license, IMO. I can even use it to download password protected Vimeo videos that I want to keep locally. Source: over 1 year ago

I use Loopback for virtual audio sources. This is super helpful because I create an audio source, which is my microphone and the guest's (guests') audio, and treat it as one input source. I use this audio source as the audio source for live captioning. - Source: dev.to / about 1 month ago

No, it's very easy: https://existential.audio/blackhole/ Blackhole is Free and Open Source. Also, Rogue Amoeba has a product called "Loopback". It's not cheap, but it's another alternative: https://rogueamoeba.com/loopback/. - Source: Hacker News / 8 months ago

At the risk of further complicating matters, you could try combining sources or otherwise experimenting with Loopback, an app that's designed to do all kinds of audio routing stuff. Source: 12 months ago
