FRB 121102 Audio Analysis

Repeating radio signals coming from deep space have been detected by astronomers.

Has anyone actually listened to these? I've processed some of these recordings and now we can all analyze them further!

As I like to play with sound here and there I was pretty immediately familiarized with the high pitched screech in these 2s clips as they sound like an accidental export of a track at 100x its regular BPM.

I reduced speed of 9 of these recordings as provided by Harvard database (see below) to about 1% of the original speed and this quickly rendered an audible, irregularly oscillating hum between approx. 20-400Hz (low bass range).
