Description: 使用Matlab AR模型的LPC函数来做特征值提取。传统方法中LPC一般用来做语音处理。这里每100个数据来做LPC，用获得的N阶参数来作为振动信号的特征值。这样10000个样本可以获得100个特征值样本集。用这些样本集可以做神经网络分类-Matlab AR model LPC function to do eigenvalue extraction. Conventional method LPC generally used for voice processing. Do LPC, where each of 100 data is obtained N-order parameter as the characteristic values of the vibration signal. So 10000 samples can be obtained the 100 the eigenvalue sample set. Neural network classifier can do with these sample sets

Description: Only coding parameters of sound generation model
• LPC is an example where parameters are a1, a2, …ak , e(n)
• Music instrument parameters: pitch, loudness, timbre, …Frequency Masking: If a tone of a certain frequency
and amplitude is present, then other tones or noise of
similar frequency cannot be heard by the human ear
• the louder tone (masker) makes the softer tone
The Masking Threshold is used by the audio encoder to
determine the maximum allowable quantization noise at
each frequency to minimize noise perceptibility: remove
parts of signal that we cannot perceive-Only coding parameters of sound generation model

Description: This a project of LPC vocoder in matlab.
El objetivo de este proyecto es implementar una codificació n de la señ al de voz medi ante un vocoder LPC y realizar ademá s el proceso inverso, recuperando la señ al sinte tizada.
Los Vocoders (“voice coder”) tienen como objetivo preservar las caracterí sticas percep tualmente relevantes de la señ al de voz. Para ello asumen un modelo simplificado d
e producció n de voz.
Se basan en modelos especí ficos de la señ al de voz, identificando aspectos relevante
s del espectro localizado de la señ al de voz, es decir, explotan la baja sensibilidad del oí do a la informació n de fase.
