Speex a free codec for free speech
Speex is an Open Source/Free Software patent-free audio compression format designed for speech. The Speex Project aims to lower the barrier of entry for voice applications by providing a free alternative to expensive proprietary speech codecs. Moreover, Speex is well-adapted to Internet applications and provides useful features that are not present in most other codecs. Finally, Speex is part of the GNU Project and is available under the Xiph.org variant of the BSD license-a very good open-source audio codecs, support for multiple audio frequency, multi-stream, Variable-rate support for a free Vorbis codec for free speech Vorbis i s an Open Source / Free Software patent-free Aud io compression format designed for speech. The Vorbis Project aims to lower the barrier of entry for voice applications by providing a free alte rnative to expensive proprietary speech codec s. Moreover, Vorbis is well-adapted to the Internet application s and provides useful features that are not pres ent in most other codecs. Finally, Vorbis is part of the GNU Project and is available under the Xiph.org variant of the BSD license

Description: Speex是一套开源的专门压缩声音的库，压缩的性能非常高，常用在VoIP或者其它网络程序中。Speex声称自己是不受任何专利限制，并授权根据修订后的BSD许可证发布。它可以用来与Ogg容器格式或直接在UDP / RTP协议下传输。
这份是Speex的编码手册英文版，下面的地址是维基百科中关于Speex的介绍: http://en.wikipedia.org/wiki/Speex-Speex is a free software speech codec that may be used on VoIP applications and podcasts. Speex claims to be free of any patent restrictions and is licensed under the revised (3-clause) BSD license. It may be used with the Ogg container format or directly transmitted over UDP/RTP.
The Speex designers see their project as complementary to the Vorbis general-purpose audio compression project.
Speex is a lossy format, meaning quality is permanently degraded to reduce file size.

Description: 本论文对Speex算法作了较为深入的研究，并在24位定点DsP芯片
上进行了实现。同时，本文还对代码优化做了一些探讨，并减少了算法
的运算复杂度，提高了编码效率。本论文主要完成了以下几项工作:
(l)把已有的算法的定点C代码转化为DSP汇编代码。在此过程中通
过运行大量的测试序列，对程序进行了反复的调试，保证程序的正确性，
期间修改了定点C中的部分溢出错误。
(2)对Speex算法的实现机理进行了较为深入的研究，并针对
ADSPZ181处理器的特点进行了优化。测试结果表明:经过优化，speex
编码算法的运算速度提高了大约40 (48MIPS一30MIPS)。
Speex编解码算法最终在一个实际的vofP电话终端中得到了应用。-ThePaPer15abouttheresearehonalgorithmandtheimPlementationon
