Quantization errors of virtual sound azimuths in different methods compared with azimuthal JND data. Smaller quantization error than JND means that obvious perceptual redundancy exists; in contrast, bigger quantization error than JND means that sensible spatial distortion exists. Quantization errors of azimuths coincided with azimuthal JND curve means nearly perceptual lossless quantization
