【摘要】：分析了傳統(tǒng)基于單聲道對的和差(M/S)編碼技術,針對三維音頻系統(tǒng)的空間特性將其拓展為基于三聲道的和差編碼技術(3D-M/S)。并提出一種基于3D-M/S的音頻編碼框架,使其能夠壓縮任意聲道配置的三維音頻系統(tǒng)。實驗結果表明與獨立聲道編碼相比,所提方法能夠在相同碼率下提高約25%的客觀質量。并且在同等質量下,所提方法引起編解碼復雜度的增加約為基于PCA編解碼方法的1/3。
[Abstract]:The traditional M/S coding technology based on mono channel pair is analyzed. In view of the spatial characteristics of the 3D audio system, it is extended to three channel based and differential coding (3D-M/S). An audio coding framework based on 3D-M/S is proposed to compress the three-dimensional audio system of arbitrary channel matching. The experimental results show that the audio channel is independent of the sound channel. Compared with the code, the proposed method can improve the objective quality of about 25% at the same bit rate. And under the same quality, the complexity of the codec caused by the proposed method is about 1/3. based on the PCA codec method.
