Figure 2 – Spectrogram of bird sound (IMAGE)
Caption
For example, Figure 1 displays a normalized sound waveform of bird sounds recorded in an urban forest
under windy conditions. Of course, this waveform is a mixture of the signals present there. However,
the signals at work can be seen using signal processing and reviewing the time and frequency domains (as
represented in Figure 2). Bird chirpings, which tend to be at high frequencies, and the sound of the wind
passing through the forest were seen in different groups.
