Description: Simulation of Residual Excited Linear Prediction (RELP) coding for speech:
This simulation give your voice or available clear wav file.This encoder have linear predictor that decreases signal s dynamic (lower quantization level). This technique also use lowpass filtering to make lower bandwidth and reconstruct it with three methods that is chosen in decoder. For example duplicate same spectrum of encoded signal that filtered in upper frequency.-Simulation of Residual Excited Linear Prediction (RELP) coding for speech:
