What is that song?

One of the biggest problems faced by music application developers is song identification – that is – given an mp3 file, how can you accurately find the name of the song, album and artist?  There are some hints in the mp3 file – the file name and the ID3 tags contain metadata about the track – but anyone who has worked with this metadata knows that this data is notoriously hard to deal with.  The metadata is often missing, inconsistently formatted or just plain wrong.  The result of this difficulty is that music application developers spend an inordinate amount of time just dealing with song identification.

Here at the Echo Nest we want to make it easy for developers to create music applications so we really want to solve the music metadata problem once and for all.  That’s why we’ve created music fingerprinting technology. Today, we are starting to release it to the world.

The Echo Nest music fingerprinter takes a bit of music such as an MP3 and identifies the song based solely on the musical attributes of the song.  No matter how messy the metadata is, the fingerprinter can identify the song since it relies on the music to do the identification.  On his blog, Echo Nest co-founder Brian Whitman dives into the technical details of the Echo Nest Musical Fingerprinter.

This is not the first audio fingerprinter in the world, but we think our fingerprinter is  distinctive in several important ways:

  • Very fast – under a second to ID a track
  • Very accurate – uses Echo Nest music analysis technology at the core. (we hope to publish some data on ENMFP accuracy real soon)
  • Open Data – all of the mapping of fingerprints to songs is open data. Anyone can get the data
  • Open server – all of the server code is open – you can host your own FP server if you wish

We want to make sure that anyone who takes advantage of the EN Fingerprinter participates fully in the ENMFP ecosystem – and so it is licensed so that  anyone who uses the fingerprinter technology will share their FP/song mapping data with everyone. No walled gardens – if you benefit from the ENMFP you are also helping others that are using the ENMFP.

It is still early days with the fingerprinter – we are doing a soft release. If you want to experiment with the ENMFP and you are at the Amsterdam music hackday this weekend send an email to with your intended use case. We will get back to you ASAP with a link to libraries for Mac, Windows and Linux.

Music Hack Days are awesome

There are now two Music Hack Days on the calendar for the next month:  Amsterdam on April 24th, 25th and San Francisco on May 15th, 16th.

The Echo Nest will be participating in both. We just love music hack days – the amount of creativity that gets packed into one room during a hack day is just amazing.  Plus it is a great way to meet developers face-to-face to see how they use are stuff.    Brian will be representing at the Amsterdam event (I think Brian really likes Amsterdam).  He’ll be showing off some new APIs that we are all really excited about – plus we’ll be giving our new API infrastructure a workout – everything will (hopefully) be faster, more reliable, better documented.

Right on the heals of the Amsterdam event is the San Francisco Hack Day.  It is being hosted at the Automattic Lounge on Pier 38 right in the city.  The event is filling up really fast – there’s lots of pent up demand for a hack day in SF – and the mention in Techcrunch didn’t hurt.  At the SF hack day if the stars align we’ll be releasing another new API feature – one that is perhaps the most requested feature of our APIs. Can’t wait.  Oh and the SF Music Hack Day is right between two other cool music events:  The Bay Area Computer Music Technology Group (BArCMuT) meetup on Thursday May 13,  and the SF Music Tech Summit on Monday May 17th.

Music and Bits


If you are heading to Amsterdam next week for the Amsterdam Dance Event, you may want to check out the Music & Bits pre-conference.  This year Music & Bits is hosting two tracks: a traditional conference-style track with thought leaders from the Music 2.0 space, and a mini-Music Hackday where developers can gather to hack on music APIs to build new and interesting apps.

The Echo Nest will be represented by founder and CTO Brian Whitman.  He’ll be giving a keynote talk about the next generation of music search and discovery platform and how  these platforms  can recommend music or organize your catalog automatically by listening to it, predict which countries to launch your band’s next tour or even help you build synthesizers that play from the entire world of music.   It looks to be a really cool talk during a really interesting conference.  Wish I were there.

This video from last year gives a taste of what Music & Bits is like:
