[Books] audiowatermark

Description: This discussion will attempt to outline some truths and common misconceptions about digital audio watermarking. It will survey the intrinsic obstacles that such technology is required to overcome, shedding light on its performance criteria, compromises and limitations. While doing so, it will also survey a few common types of applications, hopefully leading to a clear understanding as to the appropriateness of such technology and its expertise within multimedia content protection.

[Special Effects] AudioWatermarkingforContentAuthentication

Description: 该水印算法具有以下特点：1）结合音频自身的特性，不仅能够自适应划分音频数据段，而且能够智能调节水印嵌入强度，增强了数字音频水印的鲁棒性；2）能够同时进行数字音频的版权保护与内容认证，并可大致确定篡改发生区域，仿真实验表明，文中算法不仅具有较好的不可感知性，而且对常规处理具有较好的鲁棒性，同时能够对替换等而已篡改做出报警并确定被篡改位置。-The watermarking algorithm has the following characteristics: 1) combined with the audio of its own characteristics, not only adaptive division of the audio data segment, but also can adjust watermark embedding intelligent strength, enhanced digital audio watermark robustness 2) can at the same time digital audio copyright protection and content authentication, and can generally determine the tampering occurred in the region, simulation experiments show that the algorithm not only has better not be perceived, but also on conventional treatment has good robustness, at the same time be able to tamper with it to make replacement alarm and to determine the location has been tampered with.

[Other] digitalaudiocompression(AC3)A52

Description: ac3标准文档，杜比数字AC-3（Dolby Digital AC-3）是杜比公司开发的新一代家庭影院多声道数字音频系统。杜比定向逻辑系统是一个模拟系统。它的四个声道是从编码后的两个声道分解出来的，因此难免有分离度不佳、信噪比不高，对环绕声缺乏立体感，并且环绕声的频带窄等缺点。-ac3 standard documents, Dolby Digital AC-3 (Dolby Digital AC-3) is Dolby has developed a new generation of home theater multi-channel digital audio system. Dolby Pro Logic system is a simulation system. It is from the four-channel encoded by the two-channel decomposition, have poor separation, signal to noise ratio is not high, on three-dimensional sense of a lack of surround sound and surround sound, such as the shortcomings of a narrow band.

[Program doc] DABreceiver

Description: DAB接收机，包括信道解码的资料。DAB系统中载波频偏估计等。 -The Digital Audio Broadcasting (DAB) system promises to provide CD-quality sounds and flexible data services to mobile, portable and fixed receivers. In order to achieve high quality in multipath environment, a complicated channel coding and modulation scheme is adopted. This paper presents a channel decoding architecture for DAB test receiver, which accomplishes the functions including program selection, de-multiplexing, time deinterleaving, null symbol insertion into punctured bitstream and Viterbi decoding. The channel decoder was successfully realized on field programmable gate arrays and Viterbi decoding chips.

[Other] (2008)Digital_Audio_Signal_Processing

Description: Udo Zolzer2002年编写的《Digital Audio Effects》，由Jonh Wiley & Sons公司出版。作者从应用工程师的角度阐述数字音效处理技术，用大量图片代替了枯燥的公式推导，是一本难得的音频工程应用参考书。这本书的第二版也已于2008年出版，名字为<Digital Audio Signal Processing>。-A fully updated second edition of the excellent Digital Audio Signal Processing Well established in the consumer electronics industry, Digital Audio Signal Processing (DASP) techniques are used in audio CD, computer music and multi–media components. In addition, the applications afforded by this versatile technology now range from real–time signal processing to room simulation. Digital Audio Signal Processing, Second Edition covers the latest signal processing algorithms for audio processing. Every chapter has been completely revised with an easy to understand introduction into the basics and exercises have been included for self testing. Additional Matlab files and Java Applets have been provided on an accompanying website, which support the book by easy to access application examples.
