Mike, Thanks for your post.
I'm running BIAB Audiophile for Mac on a Mac Studio (2022) Apple M1 max chip
Logic Pro X 10.7.4
BIAB does not show up in the AU menu
I also find that if I open BIAB and choose the DAW window I can drag and drop audio files into a Logic project but, those WAV or AIFF tracks are loaded with snap crackle and pop artifacts.
It is very convenient to have BIAB running and displayed on a second monitor and, I have been saving the tracks as WAV or AIFF files to a folder and them doing a drag and drop into Logic. No distortion when I use that method of transferring the audio files.
