fxsmooth - smooth a fundamental frequency contour
(-i item) (-m median_smoother_ms) (-d) (-s smoothing_window_ms) (-j) sfsfile
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.
and their meanings are:
Identify program and exit.
Select input item.
Specify size of window used for median smoothing in ms.
Deglitch function. Try to remove spikes and sudden jumps.
Specify size of window used for linear (raised cosine window) smoothing in ms.
Join voiced regions with an interpolated contour to create a continuous
Any fundamental frequency item.
