Fast Radio Burst 121102 after having reduced speed to approximately 1% of original recording (original average duration 2.1 seconds, processed version average duration 210 seconds). 9 recordings of FRB 121102 were processed and the peaks of activity have beeen selected and concatenated into an approx. 5 minute video with EQ and DB monitoring. Note that the original sample (audio 1) appears at the beginning,

The hum does has a very eerie sound (like a low bassy pad) however there are two interesting aspects to these recordings. The first are the spikes in 4 of these recordings - they seem to exhibit some sort of doppler effect OR we are seeing the clearest recording at these spikes. Another interesting aspect is also the apparently silent portions of each recording during which a relatively long in duration white noise with a high frequency of above 20 kHz (appearing at 3:30-4 minutes and 4:45-5 minutes into the below file).

Note the very dynamic range in all of the recordings - they cut off from the low end at around 400Hz and cut in high end at 15-20kHz. Also note that this is NOT white noise as white noise is consistent and the oscillation at normal activity is not consistent. Finally, the pulses are perfectly seperated by equal intervals between each pulse.
