remove kiss_fft clash - 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 - Encode band shape (or just tilt)? - Make pitch less aggressive instead of using contraction? - Make energy encoding more robust to losses? - Revisit pulse spreading
