How to extract audio tracks from ISO disk image in Linux?

Found a solution, "MDF Audio Extracter", a very small utility which does exactly what we need (the way my original was MDF) — pulls out wav files of the tracks, which then can be encoded

If you skonvertit ' in something, it should work simply:
flac --channels=2 --sample-rate=44100 --endian=little --bps=16 your_disk.iso -c > your_disk.flac (options naturally do not have such)
But if the original is needed, that is cdemu, it mounted the drive and then cdparanoia will do.

The ISO is called ISO because it contains file system ISO 9660. This FS does not apply to audio CDs that contain tracks in a different format. Conclusion — you have no ISO image :)
