In this paper, we study a method of transmitting and coding three-dimensional (3D) audio signal including 22.2 multichannel. One of the transmission formats of 3D audio signal is a "scalable" format, which can transmit audio signal without increasing the number of transmitted channels. Such format can be realized by converting the original signal using matrix operation. On the other hand, the unmasking artifact may occur when the original signals are restored from the decoded signals using the inverse matrix. The proposed method estimates the quantization noise signals by the polynomial approximation of the decoded signals and reduces the unmasking artifact in the receiver side. |
