Is it possible to use JUCE to create a PC application which creates its own “software audio devices” which can be seen as audio inputs/outputs by other software? I.e. other applications could choose those for their own output and the JUCE application receives their audio and vice versa.
Technically possible, but JUCE doesn’t offer anything specific to do that.
There is a thread with valuable information/links, especially this post of @RolandMR:
Hope that helps
Hmm, seems like a fairly huge and complex undertaking
