First, sound waves do not "expand" and second they travel at ~343 at sea level in our particular atmosphere/medium.

Ummmmh, okay....? I bet next thing you'll tell me is that you can bend a light beam?????!?!?!?

In all seriousness,

"The concert was held at Foro Sol stadium, a baseball stadium with a distance of 125m from home plate to the centre field wall.

I counted 14 waves in 10 seconds, with about 0.3s between waves, so about 0.41 seconds for a wave to travel the length of the field. Speed of the wave is therefore 305m/s. The speed of sound in air at 2240m is actually 343m/s... so... it's sorta close."

No it depends on barometric pressure and humidity much more than you might imagine...

shall we call it double-woosh since you didn't get mine either

That is really cool, regardless of the minor disagreement regarding speed. Was it communicated prior to the concert that Mr. McCartney would like folks to install the app?
