I don't think there's going to be a better way than "find high quality player and decent capture device (e.g. Behringer), then press play a lot". It's possible that a truly dedicated process would capture off the tape head and then de-Dolby in software, but ultimately: it's a tape.

If you want more pain, you can correct for wow and flutter after capturing.

Key IMHO is "Speed matching to hum frequency".

There are also commercial products which does similar things.
