FX Encoder: Wrong bandwidth behaviour for OMASA 3 objects at 48 kbps with characterization items
# Basic info <!--- Add commit SHA used to reproduce--> - Float reference: 7d06ba093b47d5b10261669625fc253db94ac523 - Fixed point: 50f46e9d487823be6b25911e0863e778a7ee9b7c # Bug description In one of the P800-19 (OMASA 2TC, 3-4 Objects) outputs from the concatenated files, the bandwidth extension behaves different between float and (full-chain) fx codec. The difference is audible and at least puzzling if not annyoing. This is happening for 48 kbps with decoding to BINAURAL.
