You can "ride along" with the booster's ~30 minute journey;

Interesting recording. But way clipped! Guess he didn't know how loud it would be.

FWIW, here is the frequency make up of the middle section. I took a section from the right channel that was barely clipped.

Awesome Vids Thanks Brad for posting Very Cool ! I find that stuff fascinating.I mean Solid Rocket Boosters are awesome.If you where up close near them things they would scare the crap out you they are that Mean ! :2thumbsup:

Pano looks like it starts out around 13-14 Hz that is definately what you would feel WRT the ground rumbling and in your chest ! The kind of sound that can crack foundations ! Looks like your soundcard is getting a workout.

I love Astronomy anything to do with space exploration peaks my interest. :coffeedrinker:

Now all they have to do is install some Altecs. Voice of the Highways/Skyways in the shuttle and make it a true cruise !

He was quite a ways away. Depends on the gear too, a lot of vintage stuff you had to insert inline pads...to do it right you would have to take measurements one launch then record the next.

anyway, just though it fit here when blundered across it.

did you use the embedded player? If so download the wave file...

I downloaded the file, opened in a wave editor and had a look. But I could tell by listening that it was clipped. I pulled my sample from the right channel that has less clipping than the left.

As you say, it's hard to predict this stuff. You'd have to record one, then try again. Hopefully you'd get it right on the second try. It's not like NASA is going to give you a sound check! Looks like he overdrove the digital mic preamp.
