Summary
The topic of digital audio coding is of interest to a wide audience, including engineering and industrial professionals working in telecommunications, hardware design, music, and software product development.
Introduction to Digital Audio Coding and Standards provides a detailed introduction to the methods, implementations, and official standards of state-of-the-art audio coding technology. In the book, the theory and implementation of each of the basic coder building blocks is addressed. The building blocks are then fit together into a full coder and the reader is shown how to judge the performance of such a coder. Finally, the authors discuss the features, choices, and performance of the main state-of-the-art coders defined in the ISO/IEC MPEG and HDTV standards and in commercial use today.
The ultimate goal of this book is to present the reader with a solid enough understanding of the major issues in the theory and implementation of perceptual audio coders that they are able to build their own simple audio codec. There is no other source available where a non-professional has access to the true secrets of audio coding.
Introduction to Digital Audio Coding and Standards is based on a graduate course at Stanford University going into its 7th year. The subject material has been fine-tuned through this process to be accessible to readers of vastly differing backgrounds, levels of preparation, and interests. Exercises that apply the concepts covered are included at the end of each chapter.

摘要
數位音訊編碼的主題引起了廣泛的關注,包括在電信、硬體設計、音樂和軟體產品開發等領域工作的工程和工業專業人士。
《數位音訊編碼與標準導論》詳細介紹了最先進的音訊編碼技術的方法、實作和官方標準。本書探討了每個基本編碼器構建塊的理論和實作。這些構建塊然後組合成一個完整的編碼器,並向讀者展示如何評估這種編碼器的性能。最後,作者討論了在ISO/IEC MPEG和HDTV標準中定義的主要最先進編碼器的特性、選擇和性能,這些編碼器目前在商業上使用。
本書的最終目標是讓讀者對感知音訊編碼器的理論和實作中的主要問題有足夠的理解,以便能夠構建自己的簡單音訊編解碼器。沒有其他來源可以讓非專業人士接觸到音訊編碼的真正秘密。
《數位音訊編碼與標準導論》基於斯坦福大學的研究生課程,已進入第七年。這一主題材料經過這一過程的微調,使其能夠被背景、準備程度和興趣各異的讀者所接受。每章結尾都包含了應用所涵蓋概念的練習題。
