Basic info

• Float reference:
  • Encoder (float):
  • Decoder (float):
• Fixed point:
  • Encoder (fixed):
  • Decoder (fixed):

Bug description

The modifications in relation to how the masa2total ratios are calculated at decoder in the floating point code have been updated, to ensure optimal alignment with the BASOP code. These changes should be brought to the floating point reference. Also the BASOP code should be checked.
