WAVE文件格式剖析
- WAVE文件作为多媒体中使用的声波文件格式之一,它是以RIFF格式为标准的。RIFF是英文Resource Interchange File Format的缩写,每个WAVE文件的头四个字节便是“RIFF”。WAVE文件由文件头和数据体两大部分组成。其中文件头又分为RIFF/WAV文件标识段和声音数据格式说明段两部分。WAVE文件各部分内容及格式见附表。-WAVE as a multimedia documents used in the acoustic format, it is based
pitchana
- 在语音中提取基音频率的程序。输入为.wav格式的语音文件,输出各帧基音频率。-This is a project of pitch extract of voice. When input is a wave file(.wav), the output will be the fundamental frequency of each frame.
ica_C
- 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 Si
VAD_2
- 该程序是AMR-WB+声码器中的VAD(Voice Activity Detection)程序.测试时使用8kHz采样率,16bit量化的wav文件. -AMR-WB Vocoder the VAD (Voice Activity Dete ction) program. test the use of 8 kHz sampling rate and 16bit wav quantify the document.
WAV波形高级分析
- wav波形文件的分析,其中包括各种常见的处理,用于波形分析方面。-wav waveform analysis of the document, including all common processing for waveform analysis.
