CELT TODO

Open issues

• Change anti-collapse background noise estimator?
• Increase thresh a bit?
• Reduce waste when splitting at high bit-rate?
• Stop computing log2Amp() on uninitialized data
• Stereo/mono switching (Greg's patch and more)
• Digital silence

Tuning

• Temporal masking
• 3-tap prefilter/postfilter
• qtheta offset
• Just in case (probably not needed)
  • delta allocation for non-transient
  • fine offset
  • Spreading/folding parameter
  • Band layout (spacing)

Still possible, but probably not a good idea

• Enable new layout with more HF bands
• Remove 2-phase stereo?
• 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?

Post-freeze

• Samplerate switching
• Denorm prevention
