Why should we worry about the conservation and preservation of old analog master tapes when they've long ago been transferred to digital? It's a reasonable question—especially since AI-powered digital signal processing is on the horizon, promising perfect repair of bad-sounding digital audio files. Musicians and many audiophiles are skeptical that DSP could ever perform authentic correction on natively analog domain-transferred music files, the way (eg) Plangent Processes can. A forceful argument for better preservation of the surviving tapes is that when they're gone, we'll have lost not only the absolute (if also decaying) reference but also vital information that can be essential to applying authentic corrective processes.
