Shazam is the closest thing we have to witchcraft. I'm sure plenty of HNers will chime in with "well acktually..." type comments about how they could write it in their basement in a weekend, but to do what it does, as quickly as it does, on the ridiculously enormous library of music that it does is really something special.

Ooook I don't want to be that guy, but if you take a signal processing course in a university, you'd see that algorithms that Shazam probably uses aren't blackmagic. In UC Berkeley one of the projects we did in our Linear Algebra class was doing something like Shazam; the input was a 5 seconds of a random song tuned down so much that human hear can barely hear and white noise added. Then the problem is matching this…

I agree with the lauding of Shazam, but I am interested in your statement "I use it almost daily" -- what for? I've always viewed Shazam as a novelty and have installed and uninstalled it a few random times, but as Jobs would say it seems like a feature not a product.

I can't speak for who you're replying to, but I find myself using it at restaurants, bars, and public locations where music is playing, as well as friends' cars, and other social gatherings. I know these sort of situations are rare for the average HN user.

> and without internet That's really sweet—I wonder how much storage that requires? I would have expected it to require a lot, but if it's on a phone, then maybe not that much?

The database holds fingerprints for ~17000 songs and takes 53MBs: https://www.xda-developers.com/google-pixel-2-now-playing-so...

I like Shazam, but I love Soundhound. I've found it way more accurate and I also found their other audio tools through it. Such a cool company. Congrats to Shazam though!
