The other day I was with my son and brother in Starbucks. We were sitting at this little table drinking our coffees and music was playing in the background as usual.
There were also quite a few other people there including the several members of the Starbucks' crew. So there was a lot of noise besides the background music.
So my son pulls out his iPhone and selects this application and holds it up a little ways off the table. I said "What are you doing?" and he replied "shhhhh!" and turned the iPhone towards me so I could see the screen.
It pretty much looked like the image except that thing in the middle was moving and I think at the top was the message "sending" or maybe "analyzing" or maybe I saw both. And then the screen changed so that all of the information about the song that was playing was shown right on the iPhone screen.
I said, incredulously, "You mean that app sampled the music and was able to identify the song and artist?" He answered affirmatively although the smile on his face made any answer redundant.
I have to say that I was very much impressed. I think that's very good programming.
I since installed the program on my own iPhone. It is free. I have used it a few times. I wanted to use it while I was driving the other day but decided I needed to pay more attention to driving than Shazam!
There is a web site that further explains the application.
