CELT TODO

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 (nothing that really needs fixing, but it's still open)

• Temporal masking
• Band layout (spacing)
• qtheta offset
• delta allocation
• fine offset
• Spreading/folding parameter
