zapsilw: Zap silence periods of a time wave

Description

This function simply delete the silence periods of a time wave.

Usage

zapsilw(wave, f, threshold = 5, plot = TRUE, Sample = FALSE, ...)

Arguments

wave

a vector, a matrix (first column), an object of class ts, Sample (left channel), or Wave (left channel).

f

sampling frequency of wave (in Hz). Does not need to be specified if wave is an object of class ts, Sample, or Wave

threshold

amplitude threshold (in %) between silence and signal.

plot

logical, if TRUE plots the orginal and the new oscillograms (by default TRUE).

Sample

if TRUE and plot is FALSE returns an object of class Sample

...

other oscillo graphical parameters.

Value

• If plot is FALSE, a new wave is returned as a one-column matrix or as a Sample object if Sample is TRUE.
