I wish I could share your optimism about future developments.
Haber's work has been concerned with developing and improving his optical mechanism.
As far as I know, he hasn't done any work on audio restoration (the first demo which he
released several years ago was quite noisy), as it is not his field of expertise. But the ultra
high resolution of his scans offer much information about the nature of disc surface noises,
which may help those working to perfect noise removal processors.
