Open issues
- Spreading/folding
- Uniform quantisation
- Control over the amount of spreading/folding introduced
- Make it have the same shape as the rest of the spectrum
- Tuning
- Band layout (spacing)
- Bit allocation
- Main table
- Stereo
- qtheta offset
- fine offset
- Spreading/folding parameter
- Transients
- Energy weighting pre- or post-normalization
- Include energy shape?
- Partial remixing of short blocks?
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)
- Use a min width for ebands that's equal to the number of short blocks?
"Research topics"
- Dynamic allocation
- Better stereo coupling
