Dolby C was so bad I tried it once an never used it again. And In the 
late 70s I learned why some commercial music cassettes sounded so 
"good" compared to others - they were recorded with Doby B but not 
labeled as such, intentionally, for the extra brightness imparted. High 
speed duplication masters had Dolby B but the copie swere simply 
artificially bright, which if you tuend your treble down resulted in 
less hiss, if not accurate sound...

But no software Dolby decoder exists as far as I know! It is a 
sophisticated dynamic EQ, and with dedication could be emulated I 
should think. Hope to hear about it as soon as it has been done!
