You could probably try decoding the audio with BeLight (BeSweet) just like you would do slowing PAL audio to NTSC speeds. Then just re-encode to Dolby with your method of choice.
"C:\..\BeSweet.exe" -core( -input "c:\work folder\Audio - AC3 - 2ch - 48kHz - DRC - DELAY 0ms.AC3" -output "c:\work folder\Audio - AC3 - 2ch - 48kHz - DRC - DELAY 0ms.wav" -2ch -azid( -c none ) -ota( -r 24000 23976 )
There'll be a tiny shift in pitch, but I doubt any one would could hear it.
Thanks DrM, I will give it a shot.
