CELT TODO

Open issues

• Code
  • Laplacian energy encoding
  • Variable spreading decision in the encoder

• 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

Other decisions to make

• What should we do about remaining bits after the last PVQ?
  • more fine energy?
  • encode bands backward?
  • allow "fractional pulses"
• Minimise bits left after PVQ
  • Reverse band ordering?
  • Fractional pulses?
• Dynamic allocation
  • Include a way to deviate from the normal bit allocation?
