Detalhes da seção "A" da figura 1.
To a human listener (at least to me), the initial part of the song sounds like a series of short narrow-band noise pulses, nearly like soft clicks. The spectrogram shows something that a human cannot normally hear: each of these "soft clicks" consists of a series of 3-4 shorter pulses.
DFT window size was reduced from the default 512 to 128 samples, to improve time resolution and thus visibility of the short pulses, which are less than 5 ms in duration.
