fig1a.GIF
Fourier transform spectrogram with a narrow window of an interupted 80Hz signal and a continuous 10 and 13Hz (artificial signals).
fig1b.GIF
The same
data with a wide window.
fig1c.GIF
The same
data with a continuous wavelet transform spectrogram. Notice it resolves both time and frequency well.
fig2.GIF
The spectrogram of the sound
of two tuning forks, one producing a 256 Hz signal, the other
producing a 384 Hz signal; the second tuning fork was pulled away
from the microphone after about 0.35s.
fig3.GIF
The spectrogram of the sound of the first half of a wolf whistle.
fig4.GIF
The spectrogram of one of the authors singing the notes {\it do r\'e mi}.
