A growing collection of RedVox Reports are available at

These include a wide range of applications, but have a lot of SpaceX launches because they are loud and awesome.

We are staging a citizen science event infrasound capture for the upcoming SpaceX launch on 18 February 2017, we have a live web page at

with near-real time spectrograms from iPhones in the region. I happened to be around the Space Coast in August 2016 when SpaceX successfully launched (and landed), and we picked up some nice waveforms with iPhones, iPads, and traditional sensors.

Figure 1. Multiresolution spectrogram for Falcon 9 launch captured with an iPhone6+ around 10 km away. Time is in the horizontal axis, lower panel is pressure, middle panel is spectral energy, and upper panel is the signal to noise ratio.

Figure 2. Spectrogram for Falcon9 launch captured with a traditional sensor a few km away

Figure 3. Falcon9, infrasound array processing. Time on the horizontal, launch on the left, barge drone landing on the right. It's complicated.

Some of the traditional sensors were set up as an array, which allows us to look at very detailed detection statistics.

For the February 2017 launch we would like to consider what we can do with a network of smartphone sensors deployed by citizen scientists.

On the dead of night of Sunday 30 August  (11:30 PM local time), a cold-war Soviet spy satellite fell out of the sky right over Hawaii. We picked up infrasound from the Kosmos 1315 reentry with both traditional stations and iOS units running the RedVox apps. Analysis in progress.

If sound had a color, infrasound would fade from red to black. RedVox (Red Voice) is a reference to this imaginary synesthesia within our narrow spectrum of perception. Infrasound is everywhere: it's the fury of volcanoes, the fire of meteors, the song of the sea; it's the hum of industry, the cry of War. These are the sounds of things bigger than us, greater than us, the legendary Monsters amongst us.

The RedVox apps give you essential tools to explore this hidden world. Go find something big, deep, and awesome!
