Compression, Optimization and quality Measurement for MPEG Audio Layer 2 Coding
碩士 === 國立交通大學 === 資訊工程學系 === 85 === MPEG 音訊編碼系統第二級(layer 2)壓縮技術是一個針對 CD 音 訊 (音樂)品質而設計的共同性音訊編碼標準。然而,其編碼程序需要大 量的數學計算。在本篇論文中,我們提出一些會損害些許音訊品質的優化 技術來使得編碼程式能更快些。為了能評估出失去品質的量,我們定義了 一個標準來數量化一編碼後音訊流的品質流失率。從該定義中,我們可以 得出由編碼器編碼出有品質流失的資料流...
