Open issues

  • Reduce waste when splitting at high bit-rate?
  • 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 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

  • Temporal masking
  • 3-tap prefilter/postfilter
  • qtheta offset
  • Just in case (probably not needed)
    • delta allocation for non-transient
    • fine offset
    • Spreading/folding parameter
  • Band layout (spacing)
