Major waveform discrepency in decoding SBA packets with 15% FER

Fixed decoder sha: 77241999

Float decoder sha: d9fdb374

Encoder: d9fdb374

Renderer: d9fdb374

Test condition: -16LKFS, FOA/HOA2/HOA3, 13.2/24.4/32kbps, DTX, 15% FER

• bit_FOA: input bitstream
• pl15.g192: loss patterns

Command lines:

./IVAS_dec -no_delay_cmp FOA 48 bit_FOA dec.wav
./IVAS_rend -i dec.wav -if FOA -o out.wav -of BINAURAL

Observations:

Loss of signal amplitude when decoding some received packets, as illustrated in the following plot.
