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.
