ABSTRACT:
In an audio signal processing procedure, auto-regressive (AR) modeling is used to create a residual signal from an input audio signal. The residual signal is further added to the input audio in order to produce a processed output audio signal. The AR modeling can be performed frame-by-frame or sample-by-sample employing frequency warped Burg's method.
