Mixed In Key Beta 5.5 Detects Energy, Supports AIFF + FLAC

The popular harmonic mixing detection software Mixed In Key announced this morning an open beta test of the new version of their software, 5.5. In addition to providing support for lossless AIFF and FLAC detection, the new beta version also incorporates a brand new feature designed to help DJs quickly determine the energy level of a track.

Energy level detection is to be powered by a new algorithm in the software focused around taking multiple elements of a track to determine how hype a certain song is. Here’s Mixed In Key’s own description of the energy detection feature from the official announcement:

“Mixed In Key will show you the energy level of your tracks on a scale from 1 to 10. The value tells you how danceable that song is. House music is usually around 6-8. The biggest anthems will be 9-10. Deeper music might be 5.

It’s an amazing way to predict the crowd reaction to a specific track. Our software analyzes the rhythm, the bassline and the melody of each track to give you more insight into your music.”

My initial tests of the detection system so far have been relatively successful – just loading a few songs in and it can tell that Daft Punk is way more danceable than Death Cab For Cutie (see image below) – but then again, I could tell you that too. Where this software will shine is if it can actually make on the fly track discovery and selection choices better, just as harmonic key detection often can.

There are a number of smaller bug fixes in this release, as well as full support for FLAC and AIFF audio file analysis and a graphics upgrade for users with Apple Retina displays.ย The new version of Mixed In Key, 5.5 Beta is free to all users with a Mixed In Key 5 VIP code.

Tried out the new energy detection feature yet? We want to hear how well it’s working for you on your playlists!ย

    Is energy level for traktor in comment 2 ?

  • Reefa

    All this information should be provided by the artist or who sells the music to you.we pay enough for music without paying for expensive software.its 2013,come on iTunes,beat port,etc please give the music buyer something back and provide mixed in key information!

    i think the whole energy level thing is a big joke…

    • I agree. As a DJ, i can’t key-detect music myself (not by Piano either, never learned the skillset). But I’ve NEVER needed to be able to gauge the energy level of my music because i know my damned music. I know how danceable it is, and i can reliably predict how people are going to react (most of the time anyway). To me it’s not even a convenience feature. It’s 100% useless to me.

      With all respect to the MixedInKey team for their software, but when i have an alternate software which:
      1) Is more accurate
      2) Analyzes twice as fast
      3) Already has equivalent (perhaps even still superior) format support
      4) Has support for custom codes (meaning you can use MIK codes too, even if they’re patented)
      5) Is absolutely 100% free !!!

      …in KeyFinder ( ), and i have Traktor for BPM analysis, i see absolutely no justification for purchasing MIK.

  • Rhapz

    I can understand how people could be frustrated with this new addition. However, I don’t see it “killing” DJing as long as its only used as a small reference in choosing the next track to be played (most DJs that play seriously already have their music sorted by energy in some way regardless).

    Wave forms, phrase bars, etc. are also tools used as reference for DJs – whether you choose to use it or not just defines your style as a DJ IMO.

    And if robots replaced real DJs, I’m sure the club scene would decline rapidly since most people pay for an atmosphere rather than only coming for the music. (Unless that sob can find underground tracks, read a crowd, phrase appropriately, and not bore or tire the audience – then we’re boned).

  • I’ve been doing my own energy level system for a while now. my scale is bigger, what mixed in key calls a 9 or a 10 I call a 6 or a 7, high numbers reserved by really hard and sometimes experimental stuff (Like hard tech and speedcore). also I use 0-9 to save a digit. I don’t really trust the software enough to do my energy detection for me as it can differ from person to person.

    Still, the new file support and how it tells you how many files it’s analyzing is nice.

      same ๐Ÿ˜€ i only use the 5 stars in traktor to track my energy levels…. also anything with out a star means it has no been beat gridded yet, making finding my new tracks even easier ๐Ÿ˜€

      • I thought about doing that but it takes up too much space in the browser and doesn’t have enough levels for me.

  • Me

    How about they improve the actual KEY-DETECTION in the software. I have perfect-pitch and find MIK accurate only about 60% of the time. A bit disappointing.

    Otherwise it’s very useful software, but I will admit that they are dumbing the art of DJing down more and more. This is both a good AND bad thing.

  • ManDingo

    Energy, my nuts! The natural human element of djing is slowing disappearing. We are becoming emotionless robots to technology. I love technology, but this stuff goes to far. Just replace the human dj with a computer programmed to sync, mix(harmonically) ‘n fade (including video) and now detect energy! I got your energy right here!!! At peak time; “wow!…the music is awesome…where’s the dj?”____uh?!…he’s at the bar or outside smoking…he’ll be back in a while.”

    • Chowza

      The point is not computers can replace human djs and just sync and fade…. It’s that if you’re a dj, you should be developing new skills, finding new ways to push the technology and more creative ways to mix rather than just syncing and fading.

      In saying that, I think this goes a little far. If you can’t gauge the energy level of a track and feel the need to use software to analyze that, you should probably pick another profession/hobby.

  • lauti

    I hope somebody develops a tool that allows me to dj without hearing the music. IMHO that’s the worst par of djing: having to listen to the music.

  • Sounds awesome will the energy level show up in a dj software like the key shows up in serato?

    • Spacecamp

      So far it doesn’t seem like the energy writes to the ID3 tags – this will probably come in the full release.

      • Yakov

        Yup, I can confirm this. We’re waiting to get our DJ’s feedback about the beta to decide where to write the ID3 value. Some people suggested “Comments”, do you have any other ideas? -Yakov @ Mixed In Key

        • DJ Delicious

          Comments section would work best for my workflow.

        • dont use comments if you want the feature to be adopted. Comment section is used for lots of other different metadata, including key because of work-arounds in workflows. Also, if my comments would contain both key and energy, these are both numeric values which makes searching a tough one (search term ‘1’ would give you tracks with energy 1 and 10, and keys 1A, 1B, 10A, 10B, 11A, 11B, 12A, 12B).
          my point: pick a dedicated place in the ID3 metadata scheme

        • I’ve been putting it in the track number in rekordbox then copying it to mix name in traktor, but most people probably won’t like that. I think it should go in the comments

        • AntzInYourPantz

          He Yakov,
          Good Work! I prefer The comments. I suggest e.g. 9A – 128 – E 7

        • Comment 2 seems like the most logical to me then you can sort by energy and not have it tied to your key. The option to add in front of current comments like we have with key would be required though. Please, please, please give us the option to add it to a tag in iTunes so we can sort in there also. Something like the grouping tag would work.

      • Guest

        I vote energy in comment 2 in Traktor and please, please, please give us the option to add it to a tag in iTunes so we can sort in there also. Something like the grouping tag would work.

  • Marcus

    Does the energy level transfer over into the comment section when using traktor?

    • Spacecamp

      Not that’s apparent at the moment – right now it’s best used for making playlists with the results, but here’s hoping that in the non-beta release it will be an option to add it to the comment tags or another field..

  • Great! DJ tools are now doing magic.

  • Looks great and sutff, nice feature with the “energy” function. Although, I’m thinking maybe you should know the tracks you are playing well enough to know how ‘hardhitting’ they are?

    • Andreas

      Storing more than one thing (two discrete items of uncorrelated data) in the same field makes absolutely no sense and is worthless for searching. I.e. would you store your shoe size and IQ in the same database field? Create separate ID3 tags for BPM, Key, mood and energy level and stick with them and make sure a few different consumer/dj products use them aswell.

      NB: BPM needs to be able to store (and interpret) both a .1 and .01 decimal
      precision (for realistic DJ use)
