 == Open issues ==
-* Spreading/folding
+== Post-freeze ==
-** Uniform quantisation
+* VBR waste prevention
-** Control over the amount of spreading/folding introduced
+* More intelligent VBR decisions
-** Make it have the same shape as the rest of the spectrum
+* Denorm prevention
+* Ogg mapping (including >2ch; LM/ch switching)
-* Tuning
+[[Category:Opus]]
-** Band layout (spacing)
-** Bit allocation
-** Spreading/folding parameter
-** Stereo bit allocation
-== Other decisions to make ==
-* Should we use raw bits or now?
-* What should we do about remaining bits after the last PVQ?
-** more fine energy?
-** encode bands backward?
-** allow "fractional pulses"
-* Include a configuration packet for more flexibility? (probably not)
-== "Research topics" ==
-* Dynamic allocation
-* Better stereo coupling
-* Investigate other transient algorithms
-** Energy weighting pre- or post-normalization
-** Include energy shape
