formant_track
- 语音信号的共振峰抽取的算法-formant extraction in speech signal algorithm
Cwave
- 用C++编写的一个软件,完成对一个语音信号的内插和抽取。语音数据以wav格式、单声道存储,编码方式为PCM。可完成的功能为: (1)读wav文件; (2)写wav文件; (3)对语音数据进行内插和抽取。 -Written in C++, a software, to complete a voice signal decimation and interpolation. Wav format, voice data, single-channel storage, encodi
lpc
- 语音采样分帧,进行基音检测,以抽取的lpc参数对语音信号进行重建-The speech sample is segmented and processed by the LPC and pitch detection blocks. The synthesized speech is reconstructed from the extracted parameters.
voice-maker
- 语音信号的内插与抽取 某大学c++的实践作业-Interpolation of speech signals collected by a university with the practical operation c++
wave read
- 输入一wav格式声音信号 输出对声音信号进行抽取并插值后的频谱图(源程序为8倍重采样),并可使用play函数进行播放试听,如play(nearest),play(ori) 有ori原始音质、ups插值音质、downs抽取音质三种及以下五种重采样音质 重采样试听种类有nearest,linear,spline,pchip,cubic,插值算法详见interp1函数 可用过取消注释“高斯白噪声”、“高频噪声”对声音信号加入噪声-Wav format input-output
STC_FFT
- 快速傅里叶变换法(FFT)是离散傅立叶变换的一种快速计算方法,它能使N点DFT的乘法计算量由N2 次降为 次。下图是采样点数为8点FFT时间抽取算法信号流图,本程序也是以这种形式设计的。-Fast Fourier Transform (FFT) is a fast computational method for discrete Fourier transforms that can reduce the multiplication of N-point DFT by N2 times. T
