LPC coefficients method (no plot)

Compute the LPC coefficients using the autocorrelation methods. The coefficients can be saved in the DataSet, but are not displayed in the graphics.

coefficient type

Select the type of coefficients to be computed.


The autocorrelation method used in this algorithm computes the inverse filter (AI) and reflection (RC) coefficients (+Alphe = error energy) directly. The other types (area and log. area) are derived by converting the computed coefficients.

number of coefs

Number of LPC coefficients.

preemphasis

Factor for the preemphasis filter used for the LPC method (0 .. 1).
