Hello,
Cavern <https://github.com/VoidXH/Cavern> is a tool that I can use to
decode eac3 to ADM BWF. Is there a tool that I can use to decode Sony’s 360
reality audio format (mpeg-h 3d) to ADM BWF? (Reason being, gain is set too
high so DRC / peak limiting is way too aggressive, and I have no option to
change that.) I’ve asked everywhere and it seems like the answer is no.
Below is a mediainfo on a sample file:
