(i) The note is divided into a number of frame. Frame size is made equal to the pitch period. Each frame is passed via window and Linear Prediction Coefficients (LPC) are calculated by using L-D algorithm.

(ii) The LPC obtained are used to predict the further sample and the prediction error is evaluated.

(iii) The synthesis filter in all-pole filter. The synthesized frames are concatenated to synthesize a note.
