On a recent visit to Cape Canaveral I was lucky enough to witness
a couple of Falcon9 rocket launches and landings. I recorded the infrasound
and here is an intensity plos along with a video with 100x speedup so that the
infrasound is audible. After speedup, the ~8 minutes between launch and
landing only takes a few seconds. There is a sonic boom as the rocket
re-enters the atmosphere just before touching down. See attachments
To make the video, I made a SAC file from AmaSeis, converted from SAC with
~100x speeded up to WAV using SAC_to_WAV VB6 software, used Raven lite to
display the WAV as a screen video with sound and spectral waterfall, and then
used a video editor to create an MP4 video from the screen. Does anyone have
the VB code file for the VB6 programs like SAC_To_WAV? I would like to make
some changes to the code, and to create a windows installer that would install
on win10 or win11.
