spectrogram

Context

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()

Out:

Duration: 7.11696145125
W: 4096
ws: 128
Computing 1226 TFs
done

Total running time of the script: ( 0 minutes 4.190 seconds)
