We know that we have 55 cassette tapes, and those could run as long as 60 or 90 minutes. However, how long would an interview ideally take? 20 minutes? 30 minutes? How could you find out without listening to every tape? Assume if we used 16-bit/44.1 kHZ stereo audio and create uncompressed files, what is the low-end and the high-end of disk space we would need?

Each minute of 16-bit stereo sound at 44.1 kHz requires about 10 MB of disk space.
55 ten-minute interviews would require 55*10*10 MB, about 6 GB (rounded up).
55 ninety-minute interviews would require 55*90*10 MB, about 50 GB (rounded up).
