Analog playback on computer.

orpheus10, how are you?
I have never tried this kind of digital processing so it was interesting to read. The common opinion is that once it enters digital domain something is lost and can't be recovered. I would need top of the line equipment including computer to form my own opinion. Not a completely correct analogy, but when you translate from one spoken language into another something is always lost. If you know well more than one language, try it especially poetry.

And what if there is interference? But you did comfort me a little.

Orpheus10, I myself have no need for this, I use Nakamichi 682ZX cassette deck to make compilations from records and cds, I am just curious. Speaking of Star Trek, it's a fantasy, at least for now. One day they may be capable of doing energy/matter conversion with living beings..I don't want to think about it. However, philosophically speaking, I doubt that this kind of reconstruction would yield the exact original state. Quantum signature would be different. Now what the heck did I just say?
