 == Open issues ==
-* Code
+== Post-freeze ==
-** Laplacian energy encoding
+* VBR waste prevention
-** Variable spreading decision in the encoder
+* More intelligent VBR decisions
+* Denorm prevention
+* Ogg mapping (including >2ch; LM/ch switching)
-* Tuning
+[[Category:Opus]]
-** 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?
