Disable peak limiting #7

Closed sclsj closed 7 months ago

sclsj commented 7 months ago

Tried to decode some files I have, but it resulted in severe peak limiting. How would I tell the decoder to allow signals to go above 0dB (since we output 32 bit wav)? I tried -dse -1 but that didn't change anything.

The decoder limits the output signals by design as mandated in the ISO standard. The MPEG-H Audio system uses mandatory loudness and DRC metadata to condition the signals in the decoder such that excessive limiting is avoided.
