- The modified discrete cosine transform ( MDCT ) is the most commonly used algorithm in digital signal processing. In this paper, A MDCT spectrum optimization technique based on the subtraction of stationary sinusoidal components is presented.通過研究信號中正弦成分對改進的離散余弦變換(MDCT)的頻譜產生的影響,針對使用MDCT濾波器組的音頻編碼系統,結合正弦參數提取,提出了一種對MDCT頻譜進行優化的方法。
- But the encoded domain of MP3-MDCT ( modified discrete cosine transform ) coefficients has a fast-changing sign makes them difficult to interpolate.但是MP3的編碼域-MDCT(modifieddiscretecosinetransform)域的系數有著快速變化的符號,難以直接對它進行插值。
- Modified discrete cosine transform ( MDCT ) and IMDCT, which are lapped orthogonal transform used in signal processing, are two of the most intensive computational operation in the MPEG audio coding standard.MDCT和IMDCT是2種重疊正交變換,也是MPEG音頻標準中運算量最大的2種運算,主要應用在數字信號處理當中。
- Modified discrete cosine transform ( MDCT ) is widely used in audio compression, such as the MPEG audio layer III codec.修正離散余弦變換(MDCT)在音視頻信號編碼中得到廣泛地應用,其快速算法在實時編解碼系統中尤為重要。
