MLD in the range of 5 to 12 between signals decoded from 128kbps encoded SBA bitstreams at input level -16LKFS

Basic info

Float Encoder/Decoder: fbeb5ef8

Fixed Encoder: ae6313fd

Bug description

MLD in the range of 5 to 16 was observed between signals decoded from bitstreams from fixed- and floating-point encoders.

Input formats: HOA2/HOA3

Sample rates: 16/32/48

Input levels: -16

Encoding bitrate: 128KBPS

DTX: False

One example is as follows. (dm4aa1s14_HOA3_48_-16_128000 channel 7, MLD 14.)
