- Dynamic adjustment of energy quantisation - Psychacoustics * Error shaping within each band * Desisions on the rate - Intensity stereo option (e.g. threshold) - Dynamic (intra-frame) bit allocation - Joint encoding of stereo energy - Disable intra-frame prediction for more than X pulses - Remove contraction? - Simplify search? - Remove pulse spreading? - Encode band shape (or just tilt)? - Make energy encoding more robust to losses?
