5:45 you see the other booster in the distance.

6:57 splashdown

"Outboard SRB views from the STS 134 Space Shuttle launch [May 2011] with ғᴜʟʟ ʟᴇɴɢʜᴛ sound ( + launch radio) from the trip up and the spectacular 71km. fall back down to Earth. The boosters will propel the Shuttle to 3512 mph (5652 km/h). At 124 sec. after lift off, the SRBs have expended their fuel. They separate from the orbiter at an altitude of approx 30,4 mi.(49 km) After separation, momentum will propel the SRBs for another 70 sec. to an altitude of 44,1 mi (71,6 km) before they begin their long tumble back to Earth.

At an altitude of 2,5 mi.(4.6 km) the nose cap is jettisoned and deploys a pilot parachute. These immediately deploys the drogue parachute which is attached to the top of the cone- shaped structure at the end of the booster. At an altitude of 1,2 mi (2.1 km) the cone separates and this releases three main parachutes. These chutes will quickly slow the booster's speed from 230 mph (370 km/h) to 51 mph.(82 km/h) A motor nozzle extension is severed by a pyrotechnic charge approx 20 sec. later to prevent damage to the nozzle at impact.

At approx. seven minutes after liftoff, the boosters impact the Atlantic Ocean. The splashdown area is a box of about 7 by 10.5 mi (11 by 16.7 km) located about 140 mi (258 km) downrange from the launch pad where 2 retrieval ships collect them."

I was impressed by the sound at launch, followed by the diminishing volume, then clicks of the tank's ticks/bangs from either expansion or contraction after it had separated, then the wind noise again as it entered the atmosphere.

after the first segment, and the different camera perspectives to the same sound, you recognize when the chute pops (by the sound alone) and hear the groan of the cords straining - just before splashdown.
