SHRP - a pitch determination algorithm based on Subharmonic-to-Harmonic Ratio (SHR)-SHRP- a pitch determination algorithm based on Subharmonic-to-Harmonic Ratio (SHR)

将fft后的数据进行分谐波叠加，用来求含有谐波的声音，如人声、乐器等的基频-Fft the data after the sub-harmonic superposition is used to seek containing harmonic sounds, such as human voice, musical instruments, such as fundamental frequency

语音harmonic特征提取，先对语音信号分帧，然后对每一帧使用中心频率维基音频率的倍数的带通滤波器进行滤波，最后滤波结果的傅立叶变换的结果-Voice harmonic feature extraction, the first speech signal sub-frame, and then using the center frequency for each frame of Wiki sound frequency multiple of the band-pass filter f
