- 语音参数短时能量,短时过零率,短时平均幅度,语音端点检测,fft变换与反变换-Voice parameters of short-time energy, short-time zero-crossing rate, short-term average rate, voice activity detection, fft transform and inverse transform
speechbymatlab
- 请认真阅读采用MATLAB分析WAV文件。 步骤一:选择一个WAV文件作为分析的对象 。(ding.wav) 步骤三:进行 FFT变换并画频域图形 。 步骤四:进行该声波主要频谱的分析。 步骤五:根据该声音的频谱,反演时域图形 。(有失真) 步骤六:进行付立叶逆变换IFFT并画频域图形 。-Please carefully read the WAV files using MATLAB analysis. Step One: Select a WAV file as the
QAM_mat_vec
- 本程序是QAM的调制程序,以及我在编程时测试用的例子,还有空时分组码中的线性分散码进行处理时所需要的向量化函数VEC还有它的逆函数,希望对大家有帮助-This procedure is the QAM modulation procedures, as well as when I test in the programming examples, as well as space-time block codes in a linear dispersion code when needed
AnalogVoiceSignal
- 观测实时模拟信号(语音)的频谱 用音频设备采集一段语音,将语音存为.wav格式。对wav文件作分段傅里叶变换分析。语音是分音节的,应把它分段分析,而且实际运用中的数字信号处理的FFT的点数是有限的,一般只能达到千点。用傅里叶反变换IFFT,从频域恢复信号。画出频谱图和语音波形图。 -Observing real-time analog signal (voice) of the spectrum collected with the audio devices section of
sse_luma
- 利用vc++实现的 基于MMX汇编指令进行优化的H.264的量化和反量化程序,可以运行和输出结果,所需时间是优化前的十分之一,非常有效。-Using vc++ implementation based on optimized MMX assembler instructions H.264 quantization and inverse quantization process, can run and output the results, the time is one-tenth of
FFT_CODE
- A fast Fourier transform (FFT) is an algorithm to compute the discrete Fourier transform (DFT) and its inverse. A Fourier transform converts time (or space) to frequency and vice versa an FFT rapidly computes such transformations. As a result, fast F
Labwindows_CVI-Signal-Processing
- LabWindows_CVI作为一个用于建立自动测试系统的理想软件开发系统,提供了大量用于信号分析处理的函数,满足工程人员的需要。 信号产生实例工程“signal generation.prj”,LabWindows_CVI产生冲击信号、脉冲信号、斜坡信号、正旋信号、噪声信号、三角波信号等,在Graph控件中显示波形。 信号时域分析工程“timedomainanalysis.prj”,介绍了LabWindows_CVI信号的叠加、相关分析及卷积三种常用时域信号处理方式,将处理结果在Gra
