You're at a coffee shop. A song comes on. It's right on the tip of your tongue. You pull out your phone, tap a button, and it tells you what it is in a few seconds.

How does a phone listen to a few seconds of music through a noisy room and instantly match it against millions of songs?

Your first instinct might be that the phone is listening to the melody or recognizing the lyrics. It's neither of those. What it's actually doing is far more clever.

    I've also noticed this is why Shazaam is shit even at a concert by the original band.

    The link alludes to this when it talks about shazaam not handling us singing a song very well, but it strikes me as most stark when it's even the original artist.

    That's brilliant, thank you!

    They should cover JPEG compression at some point; when I first learned how that worked (at uni nearly 40 years ago... God) I was blown away by how beautiful that algorithm is.

    Good read. I've not heard of this site before, so now I'll check out some of their older stuff! Looks like a few years of content history to browse 🙂.

    Thanks for sharing!

    Is there something like this that can be used on a folder with mp3 or FLAC files and find out what it is and rename them correctly?
