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?
