Waterfall FFT

The Matlab scripts in waterfall_FFT.zip calculate the Waterfall FFT of a time history.

The main script is: waterfall_FFT.m

The remaining scripts are supporting functions.

The scripts also have options for spectrogram and contour plots.

Here is another script useful for tracking sine sweeps:  sine_sweep_spectral.m

  3. I want to make a 3d model from the waterfall diagram of a sound file and that’s how I saw this. Can you point me to a direction or source to do this?
