Open issues

  • Reduce waste when splitting at high bit-rate?
  • fix start/end energy prediction
  • Revert N=1 allocation special case?
  • Approximation for delta calculation
  • Revisit folding
    • Can we remove the need to fold on split?
    • Should we do L/R folding?
    • Should we fold the side (probably not)?
    • Band-aligned folding?
  • Still possible, but probably not a good idea
    • Enable new layout with more HF bands
    • Remove 2-phase stereo?
  • Tuning (nothing that really needs fixing, but it's still open)
    • Temporal masking
    • Band layout (spacing)
    • qtheta offset
    • delta allocation
    • fine offset
