Description: 语音信号进行分析、处理和设计。用MATLAB做变声器的原理是通过改变输入声音频率，进而改变声音的音色、音调，使输出声音在感官上与原声音不同。变声器是借助对声音音色和音调的双重复合改变，实现输出声音的改变。通过自己发声，共振峰频率的改变是基于重采样实现的-Speech signal analysis, processing and design. MATLAB do voice-changer works by changing the input frequency of the sound, and then change the sound of the tone, pitch, so that the output audio with the original sound in different senses. Voice Changer is the use of sound timbre and tone of the dual composite changes, realize the output sound changes. Through their own sound, formant frequency change is implemented based on resampling Platform: |

Description: 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 audio signal and extracting the sound signal spectrum after interpolation (resampling source 8 times), and can be played using the play function audition, such as play (nearest), play (ori) with ori original sound, ups interpolation quality, downs and extracted three kinds of sound quality resampling the following five types of resampling audition with nearest, linear, spline, pchip, cubic, interpolation algorithm described interp1 function can be used to abolish the comment " Gaussian white noise" , " frequency noise " of the sound signal to the noise Platform: |

Description: 在测试了ffmpeg，speex，系统acm，webrtc的音频重采样效果后，发现webrtc的质量最高，能保留更多真实信号，这对语音重采样很重要（如AEC），但是webrtc重采样的提取非常困难，并且存在不按倍数或一定比率重采样会构建失败的问题，这里提交的重采样器，效果仅次于webrtc，对于非特殊场合（不需要双工通话消除回声），都能达到很高的水平，推荐使用。-In testing the ffmpeg, speex, system acm, after webrtc audio resampling results found webrtc of the highest quality, able to retain more real signal, which is a very important voice resampling (such as AEC), but extracting webrtc resampling very difficult, and there is not a certain percentage multiples or resampling will build failure problems resampler submitted here, the effect is second only to webrtc, for non-special occasions (no need to call the duplex echo cancellation), can reach high the level recommended.
