shadyJ Posted November 9, 2015 Report Share Posted November 9, 2015 Your film sound mixes are nothing compared to nature's sound track for deep bass content: Russian Fireball Largest Ever Detected by CTBTO's Infrasound Sensors Here is a spectragram of that recording (my FFT analysis does not show below 10 Hz): From the video description: "The recording was sped up 135 times, in reality it lasted 25 minutes! The sound files were produced by CTBTO's infrasound guru Pierrick Mialle. For those interested in getting really techie, Pierrick says the sound file he produced lasts 14 seconds (which corresponds to 31.5 minutes at real "speed"). When you listen you can hear the meteorite detection for about 8 seconds (or 18 minutes at real "speed")." Link to comment Share on other sites More sharing options...
