Detailed Description

Compute Warped LPC coefficients, Pitch and Power [STILL UNDER TESTING!].

Linear Prediction Coefficients (LPC). Features commonly used in Speech Recognition research. This class is a modification of the original Marsyas0.1 LPC class. The following differences apply:

• order now reflects the LPC order (and returns <order> coefficients plus pitch and gain)
• It is possible to define a pole-shifting parameter, gamma (default value = 1.0 => no shifting)
• It is possible to define a warping factor, lambda (defualt value = 0.0 => no warping)
