FFT Spectrogram, damped sine and Gaussian packet.

Cuthbert Nyack
Applet shows the Spectrogram of a damped exponent (Fn = 0) and Gaussian wave packets(Fn = 1). The spectrogram is calculated using a sliding 128 sample window.
Fn = 0/1 show the spectrogram of a damped exponent and Gaussian with a Hamming window applied to the samples used for the FFT.
Fn = 2/3 show the spectrogram of a damped exponent and Gaussian without a window applied to the samples used for the FFT.
