Compute the spectrogram of the signal at the given time range
1 2 3  Spectrogram(signal, from.time = window$size/signal$sample.rate,
to.time = signal$duration, window = Rectangular(1024),
segment.overlap = 0, n.segments)

signal 
Source signal. 
from.time 
From time instant. 
to.time 
To time instant. 
window 
FFT window function. Custom windows are just named lists:

segment.overlap 
Segment overlap ratio (0 means contiguous segments), negative values produce spaced segments. 
n.segments 
Exact number of segments (take precedence over
