Resolve: "Decoding MDCT Stereo 64 kbps with JBM introduces click"

Mohammadreza Naghibzadehrequested to merge
basop-2491-decoding-MDCT-stereo-64-kbps-with-JBM-introduces-click into main

Reason why this change is needed

  • Wrong synthesis-buffer scaling in ivas_core_dec_fx() in case of MDCT Stereo and ACELP concealment called from stereo_mdct_core_dec_fx() --> ivas_mdct_core_reconstruct_fx()

Description of the change

  • Take into account that st->Q_syn_factor was already applied in ivas_mdct_core_reconstruct_fx()

Affected operating points

  • MDCT Stereo with concealment
  • Changes resolve occasional clicks in BASOP decoder only
  • Fully interoperable
