CELT TODO

TODO list for CELT (before freezing)

• raw bits
• Use the last bits after PVQ (for fine energy?)
• adaptive folding
  • finalize folding details
  • Decide on folding gain
• dynamic allocation
• 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
