Mastering Signal Processing with Residual Coding Scheme in Spatial Audio Object Coding

This paper presents the mastering signal processing with the residual coding scheme in spatial audio object coding. The proposed method can eliminate the difference between the original down-mix signal and the compensated down-mix signal and enhance the sound quality, successfully. Experimental result shows that the proposed method can greatly improve the performance of the original mastering signal processing and the sound quality of the proposed method is almost same with that of the output signal decoded with the original down-mix signal.
