What about decoding existing Dolby-encoded recordings?


How would you perform the calibration?


I'll have to disagree with several august posters about this.
Dolby B and C levels are referenced to magnetic levels, so any
properly recorded tape will be properly de-encoded if the
playback machine has been calibrated with a reference-level
tape, 400Hz at Dolby reference level of 200nW/m.


This is true. However I have never actually seen a machine that was
properly calibrated at the time it was used.
