Like figuring out the identity of a criminal in a who-dunnit, acoustic fingerprinting makes a copy of the music and plays it into a database to locate a match. How, you might ask, does it figure out a track of music without any metadata? The process is rather amazing. Yes, a bit goofy of a name and the website’s not much to write home about, but it is a rather brilliant piece of work. This was some time ago and now that program has been updated and improved and it is still the best $32 a person with a library can spend. This amazing program not only identified 100% of every unidentified track I owned, it also found duplicates, fixed names, years, and provided better cover art than I had.

How is it that I found out the name? I ran it through a program that fixed much of my library. It was Buddy Holly off an obscure album I had never heard of called Buddy Holly, From the original master tapes. No, I reasoned, it can’t be Costello because it sounds too much like Buddy Holly, yet…the recording quality sounded modern, much better than anything I associated with Holly. One particular track I swore must have been by Elvis Costello. It had all sorts of great music some I recognized, many others I did not. I received a demo disc from someone at a tradeshow. Or maybe a few duplicates, or some without cover art.

And yet, there’s still unknown tracks and artists within my group of tunes. I have spent hours upon hours curating mine–grooming it to perfection. Without metadata we don’t know much of anything about a track of music.įew of our libraries are perfect.

In short, metadata has all the information we need except one: the actual music itself. Metadata is digital audio’s underlying information of what tracks are what, the name of the performing artist, band, cover art, liner notes, sample rate, filter type, release year, track number, etc.
