Description: 直接压缩成mp3的录音机程序，录音过程中不需要产生.wav文件，边录音边压缩，处理速度快，节约磁盘空间，尤其对长时间录音非常合理。本程序可以录制单声道、立体声、左声道、右声道的语音。录音和播放过程中都有实时的波形显示。特别感谢我的好朋友李志刚的指点，由于他的提醒，我从使用mciSendXXX()改用waveInXXX()。-directly into compressed MP3 recorders procedures, the process of recording have not. Wav file, while recording edge compression, fast processing speed and save disk space, especially for long recording very reasonable. This procedure can record mono, stereo, left channel, right channel voice. Recording and playback process have real-time waveform display. Special thanks to my good friend, Li Zhigang's instructions, he reminded, I use mciSendXXX () switch waveInXXX (). Platform: |

Description: 在linux平台下,纯c写的盲信号分离的代码.它采用基于卷积混合的盲信号分离算法,不但可以分离人工合成的混合信号,而且对于真实环境中的卷积混合的语音信号也能够分离.在本程序中,包含了两个测试文件,makefile后便可以直接使用.
另外值得一提的是,压缩包里包含有一些语音处理方面的常用函数.例如fft变换,读取\\写入wav文件,以及一些常用的一维向量和二维矩阵变换的函数.这些可以直接应用在其他应用程序里去.-in linux platform, net write c Blind Signal Separation code. it is based on convolution of mixed Blind Signal Separation algorithm, not only can be separated from the artificial synthesis of mixed-signal, but for the real environment convolution of mixed voice signals can be separated. in this procedure, the tests included two documents, makefile can be used directly after. Also worth mentioning is that Compression bag containing some of voice processing functions commonly used. fft transform, for example, to read \\ write wav file, and some of the commonly used one-dimensional and two-dimensional vector matrix transformation functions. these can be directly applied to other applications going.

Description: This project features a full-hardware sound compressor using the well known algorithm: IMA ADPCM.
The core acts as a slave WISHBONE device.
The output is perfectly compatible with any sound player with the IMA ADPCM codec (included by default in every Windows). Includes a testbench that takes an uncompressed PCM 16 bits Mono WAV file and outputs an IMA ADPCM compressed WAV file.
Compression ratio is fixed for IMA-ADPCM, being 4:1.

1）读入原始的WAV语音文件（Audio sample rate:8khz,Audio sample size:8bit）
2) wav语音文件转为PCM语音文件
3）对PCM语音文件进行G.726压缩编码
4）对压缩后的文件进行解压缩转为PCM语音文件
5）把PCM语音文件转为WAV语音文件-g.726 speech coding standards for the use of the functions of the whole process is as follows: 1) read the original WAV audio files (Audio sample rate: 8khz, Audio sample size: 8bit) 2) wav audio file to PCM audio file 3) G.726 PCM voice files on the compression 4) the compressed files to PCM audio files extract 5), the PCM audio files to WAV audio files Platform: |

Description: 文件压缩技术的日新月异使得MP3成为时下最烫手的音乐格式，优质的音乐随着0与1的排列迅速散布到世界各地，撼动人心。何谓MP3？MP3的全称是MPEG Audio Layer 3，它是一种高效的计算机音频编码方案，它以较大的压缩比将音频文件转换成较小的扩展名为.MP3的文件，基本保持原文件的音质。MP3是 ISO/MPEG标准的一部分，ISO/MPEG标准描述了使用高性能感知编码方案的音频压缩，此标准一直在不断更新以满足“质高量小”的追求，现已形成 MPEG Layer 1、Layer 2、Layer 3三个音频编码解码方案。MPEG Layer 3压缩率可达1:10至1:12，1M的MP3文件可播放1分钟，而1分钟CD音质的WAV文件（44100Hz，16bit，双声道，60秒）要占用 10M空间，这样算来，一张650M的MP3光盘播放时间应在10小时以上，而同样容量的一张CD盘播放时间在70分钟左右。MP3的优势是CD难以比拟的。-File compression technology with each passing day makes the MP3 music format to become among the most hot, high-quality music quickly spread with the arrangement of 0 and 1 around the world, to stir the hearts.
