+[[Category:Opus]]
-** Band layout (spacing)
-** Bit allocation
-*** Main table
-*** Stereo
-*** qtheta offset
-*** fine offset
-*** energy prediction parameters (means, decay)
-** Spreading/folding parameter
-* Transients
-** Energy weighting pre- or post-normalization?
-** Include energy shape?
-** Partial remixing of short blocks?
-* Dynamic allocation
-** Include a way to deviate from the normal bit allocation?
-* Better stereo coupling
-** Better support for "intensity stereo"?
-== Other decisions to make ==
-* Should we use raw bits or not?
-* 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)
-* Use a min width for ebands that's equal to the number of short blocks?
