FXSMOOTH

NAME

fxsmooth - smooth a fundamental frequency contour

SYNOPSIS

fxsmooth (-i item) (-m median_smoother_ms) (-d) (-s smoothing_window_ms) (-j) sfsfile

DESCRIPTION

fxsmooth is a program to smooth a fundamental frequency contour stored in an fx item. A number of smoothing technqiues are available: (i) the deglitch algorithm attempts to remove sudden jumps in the contour; (ii) the median smoother replaces each Fx value by the median of the values found in a window symmetrically placed around the sample; (iii) the linear smoother applies a raised cosine window symmetrically about each voiced value, (iv) the interpolation function joins up the voiced regions so that a continuous curve is obtained.

Options and their meanings are:

-I Identify program and exit.

-i item Select input item.

-m median_smooth_ms Specify size of window used for median smoothing in ms.

-d Deglitch function. Try to remove spikes and sudden jumps.

-s smoothing_window_ms Specify size of window used for linear (raised cosine window) smoothing in ms.

-j Join voiced regions with an interpolated contour to create a continuous curve.

INPUT ITEMS

FX Any fundamental frequency item.
