Can anyone suggest software to plot this data
to display the dopper shift? Perhaps a stacked
3D spectra-time plot, or a 2D waterfall of frequency vs time? Of

any of the Amaseis file formats or any of the
WinQuake formats as program inputs.
For waterall displays of WAV files, I use the free Raven Lite program:
I have my own programs for converting SAC and WinQuake files to WAV
I will try to see if I can do anything with your file, but it is so
short the waterfall will not show much. Faster sampling would help.
Waterfall displays are helpful for analyzing music and bird songs, but
for not much good for earthquakes, for example.
