lpreson

lpreson --  Modifies the spectrum of an audio signal with time-varying filter coefficients from a control file.

Description

Modifies the spectrum of an audio signal with time-varying filter coefficients from a control file.

Syntax

ar lpreson asig

Performance

asig -- an audio signal to be modified.

lpread gets its values from the control file according to the input value ktimpnt (in seconds). If ktimpnt proceeds at the analysis rate, time-normal synthesis will result; proceeding at a faster, slower, or variable rate will result in time-warped synthesis. At each k-period, lpread interpolates between adjacent frames to more accurately determine the parameter values (presented as output) and the filter coefficient settings (passed internally to a subsequent lpreson).
