Open issues
- Code
- Laplacian energy encoding
- Variable spreading decision in the encoder
- Tuning
- 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?
