Real Sounds
Here are five real sounds: four are music, one is speech. First, listen to each of them by clicking on the icon:
These sounds range from a simple computer generated scale to a recording of a piano playing Fur Elise. A recording of a male voice is also included. These "real" waveforms are so complicated that plotting them vs. time wouldn't show us much. (You can plot them if you want. See the MATLAB section.)
Show the spectrum for each signal.
Does each spectrum change with time? Did the changes make sense? Go up a level to "Chirps" to see if you can predict the spectrum of a signal, or a signal from it's spectrum.
Go back up to continue.
