[regression-merge] Decoder OMASA rateswitch JBM increased MAX_ASB_DIFF

Basic info

Status quo:

  • Encoder (float): ivas-float-update (c2135116)
  • Decoder (fixed-point): main (b480684c)

Post-merge:

  • Encoder (float): float-pc-clone-for-merge (92d4831d)
  • Decoder (fixed-point): main-pc-clone-for-merge (10615874)

Bug description

OMASA rateswitch into 32 kHz STEREO output with JBM shows increased MAX_ABS_DIFF.

Output signals from float enc + float dec status quo (Reference) and post-merge (Test): dec_6_Float

Output signals from float enc + BASOP dec status quo (Reference) and post-merge (Test): dec_6_BASOP

Main change is at time instant just before 1s.

There is quite large MAX_ABS_DIFF already in the pre-merge state, so maybe this is not a significant problem in this merge.
