Ahh, Ok - thanks for the info.
Would be a handy feature.
FWIW wanting to use fdk is related to the etsi doc I posted in the other
I was going to try and add some debugging to see what, is any, ancillary
was broadcast in the UK (like heavy compression and mixdown). I know
from adding debugging to ffmpeg aacdec that drc is broadcast, but
couldn't find mix down meta.
