Old TODO list

  • raw bits
  • Use the last bits after PVQ (for fine energy?)
  • adaptive folding
    • finalize folding details
    • Decide on folding gain
  • dynamic allocation
  • Using PVQ for coarse energy?
  • configuration packet
  • revisit stereo coupling
  • stereo allocation
  • tune everything
  • increase max pulses
    • more pulses for N>5
    • Fast CWRS for N=3
    • change if(_n<=6) to if(_n<=6 || _m>255) in ncwrs_u32
    • Use real limits in fits_in32()
  • Tune for lower sampling rates
  • Improve dynamic range by changing the energy floor
  • Laplace encoder
    • Make ft=32768 to save some divisions
    • Use the last symbols to have a wider range
  • Investigate other transient algorithms
    • energy weight
