Turn music, voice, data files into ISO's

I need to know how to turn .he2 files, .he4 files, .(a) files, .(b) files, .he0 files, .he1 files, .he3 files, and .he9 files into ISO's, so I could extract the sound, music, game data files, maybe the backgrounds, and art from those files. Is there a working software so that I could turn them into ISO's?

Any software can turn files into ISO images, I use the free Imgburn. But I think you're mixing up file formats here. Try Audacity to extract the audio, import -> raw. Most of the other formats, at least with the SCUMM adventures are proprietary, so good luck there, unless you know any crazy skilled hackers.

I mean, extractable ISO's. You could extract the music and sound from .he4 and .he2 files which were turned into .ISO's.

No you couldn't. They'd still be normal files, just in an archive. A few people have made extractors that can write to WAV files, but that's it.
