# Example
# --------
#
# In the following example, we compute and plot a spectrogram
# from a signal emitted by a dolphin to see the time-frequency components
#
from spectrum import Spectrogram, dolphin_filename, readwav
data, samplerate = readwav(dolphin_filename)

p = Spectrogram(data, ws=128, W=4096, sampling=samplerate)
p.periodogram()
p.plot()
