shazam
I hope you’ll forgive me a post as off-topic as the picture accompanying it is peripatetic. As far as I can tell, it has no algorithmic trading application. But I’ve spent my life around software and it’s pretty rare that I find something that truly wows me.
And Shazam is one of those rare beasts.
I don’t know how they do what they do, but what they do is really something else. Install a free iPhone application (I think there are other implementations available as well), start it up and point the phone’s mic at the source of some music. In a few seconds, the software will identify the song, download its album cover and assorted info, and point you to where you can purchase the song. It’s not perfect - it couldn’t identify the beginning of Beethoven’s 5th, but it was able to identify Carmina Burana and had no problems with any popular music I pointed it at.
I’m certain that if you had a contest between this system and your favorite neighborhood audiophile, Shazam would win hands down for speed and accuracy. It’s really something else.
Agreed its one of those application that truly wows and it recognizes foreign language songs as well with ease
