Open issues

  • Enable new layout with more HF bands?
  • Prevent errors at very low bit-rates
  • Reduce waste when splitting at high bit-rate?
  • Remove 2-phase stereo?
  • fix start/end energy prediction
  • Revert N=1 allocation special case?
  • Revisit folding
    • Can we remove the need to fold on split?
    • Should we do L/R splitting?
    • Should we fold the side (probably not)?
    • Band-aligned folding?
  • Tuning
    • Band layout (spacing)
    • TF resolution options
    • Bit allocation
      • Main table
      • Stereo
      • qtheta offset (all 3 modes)
      • delta allocation (all 3)
      • fine offset
      • energy prediction parameters (means, decay)
    • Spreading/folding parameter
