Pitch_extraction_procedures
- 基音提取程序,对于给定一段语音,按一定时间分帧,并从中提取出基音频率-Pitch extraction process, for a given period of voice, according to a certain time-frame, and extracting the pitch frequency
watermarking
- 对音频信号分帧加窗,对每帧进行三阶小波变换,取其逼近系数平均值(一般为零).在此嵌入二值图像 并有对潜入水印信号进行盲检,恢复其嵌入水印-Sub-frame of the audio signal increases the Hamming window for each frame impletment third-order wavelet transform, whichever is close to the average coefficient (usually zero). a
vad_VCPP

enframe
- 音频分帧,将音频信号按一定间隔分成小段,同时加窗-Audio framing
chengxu1
- 音频信号的分帧,fft,相关性分析。自己编的,可生成图像。其中也加了注释- Sub-frame of the audio signal, fft, correlation analysis
分帧
- 之前找了分帧的程序好久,都没有找到完整的,最后自己看分帧算法写了一个,效果还好。(Before looking for a frame of the program, for a long time did not find the integrity, and finally see their own frame algorithm, wrote a, the effect is good.)
分帧加窗函数
- 分帧加窗函数,我做音频信号频谱分析时用到的一个函数
