It is not possible to create an ISO image that represents an audio disc, because ISO images contain a file system structure that audio discs do not have. That’s if I understand your question.
It has been many years since I used CDemu to mount .bin/.cue of audio CDs, but it did work for me:
Found my notes…
NOTE: To rip an audio CD compatible with cdemu, from IsoBuster for Windows select the disc, select “Extract CD ”, select “RAW”, and save as a BIN. The CUE will automatically be created to match the BIN. In cdemu mount the CUE.
use cdrtools to create ISO 9660 standard file system
Audio cd had different file system it’s just flat PCM with indexing address
maybe there a util to write list of audio files into music cd iso
