Linear Predictive Analysis of Speech – Video Tutorial

Linear Predictive Coding (LPC) is a method to compute an autoregressive (AR) model which replicates a desired power spectral density. In Speech Enhancement for Android you can create an LPC-AR model of any audio signals which are loaded into the workspace. This video shows how you can generate the LPC spectrogram and it also demonstrates how you can analyse the LPC spectrum for each short-time frame.
