SoundHound came out with this feature in their iPhone app in 2008. It worked well in my experience. It’s amazing how quick we are to go ooo ahhh when big tech replicates what is already common place in little tech or academia.
I remember that, and I remember playing a game with my girlfriend at the time where we tried to get it to recognize any song we hummed. We had an in-joke where Smooth Operator was literally the only song we could get it to recognize. This isn't just "big tech replicating a commonplace feature", it's big tech implementing it at all where little tech could not. This is a common fetishization on HN, but HNers forget tha…
SoundHound is definitely not a tech demo.
