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: 512kbps

DTX: False

One example is as follows. Upper channel is fixed-point output, lower one is floating-point. (dm4aa1s14_HOA3_48_-16_256000 channel 7, MLD 16.)
