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.

Description: 本程序将指定的16K采样的语音数据文件转换为经G.723编解码后的8K语音数据。降采样前先使用180阶的FIR滤波器对语音数据进行频率压缩，然后进行抽取，并对抽取的数据进行G.723编解码。该程序在非特定语音识别的库文件处理中使用，也可扩展至其他用途。-this procedure will be designated the 16K sampling voice data files converted to G.723 codecs by the 8K words Music data. Sampling down before use 180 bands FIR filter frequency voice data compression, then proceed to collect, also collected data G.723 codecs. The procedures in non-specific voice recognition for the use of document processing, and can be expanded to other uses. Platform: |

Description: Music Coding
LPC-based codecs model the sound source to achieve good
compression.
Works well for voice.
Terrible for music.
What if you can’t model the source?
Model the limitations of the human ear.
Not all sounds in the sampled audio can actually be heard.
Analyze the audio and send only the sounds that can be heard.
Quantize more coarsely where noise will be less audible.-Music Coding
