AI-powered enhancement of voice recordings

Adobe Enhance claims to improve the quality of audio recordings. Such things already exist (and are supremely useful to journalists) for making low-quality interview tapes more easily transcribed, but Adobe promises more: it "makes voice recordings sound as if they were recorded in a professional studio."

I feel the killer app for this is most likely to squeeze "new" songs out of dead recording artists by going through their demo tapes and such.
