Bear in mind, that by shifting the audio to match at the pad, sounds near the camera occur before their causes. I was impressed that there were no verbal exclamations by the camera operator, but the clicks and musical sound* in the 1:00 to 1:06 could have been caused by the cameraman, and have no connection to the pad. The "cymbal clap" at 1:09 sounds like birdsong to me.

* that musical sound reminds me of a radio mike key sound that some family service radios make.

For anyone interested ...

I edited a copy of the USLR video, synced the audio, increased audio by 10 dB, added outlines for fireball + rocket, and added zoom insets. Background sounds that Elon mentioned are audible ...

1:00 : faint clicking sound, continues thru explosion
1:05 : musical sound
1:06 : clunk sound
1:07 : click sound
1:09 : symbol clap sound
1:11 : explosion

+ time-lag for sound to arrive ~ 12.07 seconds.
+ approx. distance from rocket ~ 2.55 miles or 4.1 km
