Key Detection Software Comparison: 2015 Edition

Since our last key detection software square-off almost two years ago, we’ve seen new iterations of DJ software continue to incorporate key analysis. Serato DJ enters the fray, and Rekordbox is vying for status as a DJ platform. Want to know what software has the best key-finding algorithms, and which still need an overhaul? Read on for our test results.

Two Key Detection Tests

Major / Minor Triads (“Control”) – In our first test, we crafted 24 very simple songs, consisting of an basic house drum loop and a piano playing a major or minor triad for each of the keys. Some softwares understand this pretty well, others get completely thrown off by how simple the solution is – the results are always fascinating.

Real World Test – Like last time, our real world test consists of 66 tracks from Beatport – the top three songs from every genre on the platform. This is designed to mirror what DJs might be playing on dance floors right now around the world, which is what these softwares claim to be able to detect the key of. We ran songs through our human key finding experts and 10 different softwares to see how close software can come to the human ear.

Human Testers VS Key Finding Algorithms

I’ll repeat what we always say when talking about harmonic mixing – “trust your ears!” It’s critical to not build a dependency on tools, but instead use them to augment a sense of when something works or doesn’t. We’ve heard from some sources that even a groups of pitch-perfect classically trained musicians have a significant rate of disagreement about the key of certain songs.

Like last time we did a test like this on DJTT, all the songs had to have a consensus from the human group to be included in the final results. Our human test group included myself and 5 well-suited volunteers with experienced ears from the DJTT community.

We all pain-stakingly listened to every song and came up with the best choice for the key of the song. Despite coming to a consensus (simple majority) on each track, maybe six sets of  ears could be wrong. All of the data is available as a free download at the end of this article (or click here), and if you disagree, feel free to make a case for a different consensus on a track in the comments.

The Key Analysis Competitors

Beatport’s Store Tags

We’ve read many reports around the web of Beatport using their own internal software to determine the key of tracks – something that is backed up by the data. Our understanding is that the keys are not just what the label reports to Beatport when submitting them – so we decided to analyze how accurate the keys that come with purchased tracks are on the Beatport store.

Major/Minor Triad Test: Not possible – no way to manually test.
# of correct tracks (vs human volunteer consensus): 40 (61% correct)
# of Major / Minor misreads: 13

Serato DJ 1.8

With 1.8 only just becoming public a few weeks ago, this is easily the newest key detection algorithm in the industry. We were impressed at a strong initial showing from Serato in this roundup. With the addition of the Pitch’n’Time DJ key shifting in 1.8, Serato have a major win for harmonic mixing DJs on their hands.

Major/Minor Triad Test: 67% – eight incorrect.
# of correct tracks (vs human volunteer consensus): 46 (70% correct)
# of Major / Minor misreads: Only 1 – this doesn’t seem to be an issue for Serato DJ

Mixed In Key 7 (and 6)

Mixed In Key’s algorithm remaining the reigning champion in this domain, but did the new update to the software from 6 to 7 make a difference? In our testing, the results were identical – meaning that if an upgrade is only really important if you’re looking for auto-cue points, better energy levels, etc – in terms of the results in key detection, there was no difference. Either way MiK landed the top slot yet again!

Major/Minor Triad Test: 75% – six incorrect.
# of correct tracks (vs human volunteer consensus): 57 (86% correct)
# of Major / Minor misreads: 2

Virtual DJ 8.0.0

Since the last test, Virtual DJ finally rolled out their version 8 update to the software – but it was too much to hope that the key detection algorithm had improved with this new update. It’s the lowest-scoring software in the lineup, and for some reason was unable to get any of the Major/Minor triad test correct

Major/Minor Triad Test: 4% – only one correct, because it returned G#maj for every track.
# of correct tracks (vs human volunteer consensus): 27 (41% correct)
# of Major / Minor misreads: 10

Rekordbox 3.3.0

Since the last test, Rekordbox has gone through two iterations – one of which involved the entire rewriting of the code base and complete ownership by Pioneer DJ (they previously outsourced development to Mixvibes). Rekordbox 3 had a pretty mediocre showing, but actually out-performed in the Major/Minor Triad test.

Major/Minor Triad Test: 96% – one incorrect.
# of correct tracks (vs human volunteer consensus): 34 (52% correct)
# of Major / Minor misreads: 10

Rekordbox 4.0.2 / Rekordbox DJ

Up next is the most recent version of Pioneer’s DJ software and library tool – and there’s serious improvement in Rekordbox 4. We suspect that this was a focus of attention considering that they’re hoping to win over Traktor and Serato users with the rollout of the new performance mode in the software. It’s fascinating to see this algorithm tied with Serato DJ, considering so many other elements between the two softwares already feel very alike.

Major/Minor Triad Test: 46% – 13 incorrect.
# of correct tracks (vs human volunteer consensus): 46 (70% correct)
# of Major / Minor misreads: 7

Traktor Pro 2.10 (and Traktor DJ)

We’ve got many wishes for what Traktor Pro 3 might include – but better key detection has been on the wishlist for a while. Even with increasing focus on live performance, Native Instruments hasn’t made any efforts to improve the identical mediocre key detection on the desktop or iOS platform.

Major/Minor Triad Test: 42% – 14 incorrect.
# of correct tracks (vs human volunteer consensus): 31 (47% correct)
# of Major / Minor misreads: 16 – this is clearly a big part of the issue.

Beatunes 4.5.6

We like including this standalone piece of playlist-creation and music analysis software because it’s unique and different. There’s all kinds of features designed for playlist curators – and it actually fares pretty well in the key detection showdown. Virtual DJ and Traktor have something to learn from Beatunes.

Major/Minor Triad Test: 96% – only one incorrect.
# of correct tracks (vs human volunteer consensus): 43 (65% correct)
# of Major / Minor misreads: 11

Keyfinder 1.26

Keyfinder is the only free piece of software on this list – and likely the best hope for beating Mixed In Key someday. While the 2.0 version of the software was taken down due to crashing issues, 1.26 still does pretty well in this contest. We’re waiting on a copy of 2.0 in the next week and we will do a followup article to see how it fares.

Major/Minor Triad Test: 33% – 13 incorrect.
# of correct tracks (vs human volunteer consensus): 43 (65% correct)
# of Major / Minor misreads: 5

Our Major Conclusions

  • Mixed In Key 6 and 7 are the same, but the best: The new iteration of the best key detection algorithm out there seem to use a nearly identical (but solid) algorithm.
  • Traktor and Traktor DJ still identical: Despite a continued drastically different feature set on desktop and iOS, the two softwares do still have the same key detection algorithm. We tested every single song anyway just to be sure – but the results were identical.  
  • Humans don’t always agree: As with every time you get a group of people together and get them to identify the key of a track, there will be disagreements. In this round, many of the second-place human results were similar to results that some of the algorithms found – meaning that even if the algorithms are getting some wrong, they’re often getting tricked by the same things a human ear might be.
  • Rekordbox got way better: A sign that Pioneer really has taken their foray into the world of digital DJ software seriously. Rekordbox 4 is nearly a 20% improvement over the last version of the software, tying it with Serato DJ
  • Serato DJ is strong: The newcomers are doing well in this shakedown – and considering Serato’s desire to remain competitive, we could easily see them continuing to improve their key detection algorithm in the next few versions of the software.
  • The baseline test can be deceiving: Despite us designing this to be a basic test of key detection, many softwares completely failed. Perhaps they were looking for something more complex in the song. Virtual DJ especially had no idea what was happening in this test – returning “G#maj” for every single track.
  • Some tracks can be pretty ambiguous: Specifically we had one track that no algorithm “got right”. Our human judges consensus was that the David Temessi Remix of Dual Fuel’s “Humano” was in Amin, we got a host of other thoughts from the softwares. Listen below and enjoy how hard this one is to figure out (most songs were more cut-and-dry):

    How about a 2016 update for this so well made article?

    • Sjoerd van der Sanden

      Yep, or 2017

  • iCE

    We released new bpm and key detection software few months ago. Not all features inplemented yet, but it fast and accurate. Give it a try!

  • BoldFaceType

    If the material and authors/listeners from the 2012, and 2014 tests are still handy you might wanna try this using the same songs and criteria from those years. Just for some context and consistancy. Seems like it may be alot of work though. If so, maybe you could archive your research in such a way that it would make it easier for you, or someone else to revist the project in the future? Just a thought.

  • Fayek Helmi

    I have said this before but i’ll say it again, in my experience between MIK, traktor’s built in detection and KeyFinder, KeyFinder takes the winning cake. NIK for me is a bloated, internet dependant software that takes a lot of resources for very mediocre results. traktor’s detection is definitely a long way from being reliable and KeyFinder has never let me down.

    Don’t judge these things based solely on reviews and comparison charts on blogs people, try them out yourselves, do your own control tests and judge for yourself which fits your work the best.

  • Paul

    @Dan White: I really like your comparison. I only wish you would present the results in a uniform way. So for all three results either # first and % n brackets or the other way around.

    And please do not show the # of incorrect “answers” with the triads, whereas the # of correct “answers” with the humans – at least to me that is confusing. Just one measure, e.g. correct “answers”in all three lines would make it clearer.

    Please let me leave that as a request for the next round 😉

  • Paul

    there seems to be an error in the results of Keyfinder with the Triad Test. If it had 33% correct, it should be 16 incorrect (as two thirds of 24). Or it has 13 incorrect, so 11 of the 24 correct, which should result in a 46% score (as with rekordbox 4).

  • Tito Pacheco

    Ok, It’s An xlsx File. How Does This Work?

    • Dan White

      Microsoft Excel, the standard in spreadsheet softwares. Or use Google Sheets.

      • Psythik

        Next time you should go with the good old fashioned .xls extension, that way everybody can open the spreadsheet no matter how old their copy of Excel is

  • Treadway

    “We’re waiting on a copy of 2.0 in the next week and we will do a followup article to see how it fares.” Does this mean KeyFinder 2.0 is finally coming back on line next week? …please

    • Ibrahim Sha'ath

      It doesn’t, unfortunately. I’ve sent Dan a build for his followup article but it doesn’t write to tags, which is where the crash is coming from.
      I have an enormous amount of Real Life happening right now (new kid, new job, new continent) and KeyFinder just isn’t a priority, sorry.

      • BoldFaceType

        Nothing has burned down, your wife and kid are breathing, you still have a job, and no one speaks English here anyway. You’re doing fine so far Ibrahim. Thanks for the post and sending out the latest build. Welcome, Congradulations and Good Luck!

  • calgarc

    meh… don’t use key detection software 🙂 no problems here

  • 7

    Is platinum notes no longer popular? I used to see people bring it up every time MIK was talked about.

    • Ricardo Martínez

      I definitely still use it. It’s totally amazing the amount of clipping in tons of tracks, whether from DJ stores or record pools.

    • YV_Miami

      It’s used by a HUGE number of Mixed In Key fans. It’s just less glamorous than key detection so it’s talked about less. In case you didn’t know, Platinum Notes combined a lot of new algorithms written by the Mixed In Key team with the IRC Limiter and Multiband Compressor/Expander that’s licensed from iZotope Ozone… so it’s like an automated Ozone for your tracks, but with Mixed In Key’s special sauce to make it improve 1000s of files with one click. We’ve been fans of iZotope for many years and licensed their technology the moment we could afford to do it. That’s how Platinum Notes was born.

  • BoldFaceType

    You’ve got some glaring omissions here Dan. I understand these selections may be “the most requested”, but if you referenced the 2014 article you’ll see that the lineup is nearly identical except for Algoriddm DJ and MixVibes. Everyone has heard of them, and they were featured in the last key test article. Why not include them?!! Especially when MixVibes (highest rated *DJ* software) had the 2nd highest score (from a different manufacturer) of all the programs tested! You should be flamed White. That’s like not giving Rousey a rematch. Not reviewing a MixVibes product is like not touching gloves at the beginning of a match. You should definitely amend this article b/c it misses some major points.

    • Ibrahim Sha'ath

      MixVibes uses KeyFinder.

      • BoldFaceType

        Thank you for clearing this up Ibrahim. I’ve been using MixVibes for years mostly b/c it’s excellent key detection produces an outstanding mix. I had no idea it was your Key Finder behind it. I really don’t think this is common knowledge so I’m glad you took time out of your very busy schedule to inform us. I’m looking forward to Dan’s review of the 2.0v, and I’m hoping it will generate more interest in this very worthy labor of yours. Cheers.

    • Dan White

      Thanks for the feedback. I’d be happy to test these – MixVibes uses Keyfinder (as Ibrahim notes in the other comment – he’s the developer behind Keyfinder) – but Djay could be included.

      The process for testing (I do it twice, for accuracy verification) and transcribing all of all of these results is excruciating, so I made the decision to limit the number of softwares tested in this roundup.

      • BoldFaceType

        Dan, I appreciate that this is tedious, difficult work for surprisingly little pay. Thank for your efforts on our behalf. As you can see, this has already proven to be a popular piece on DJTT. Bravo. That being said, of all the cuts you had to make Dan… In any event, I’m looking forward to a follow up. I’m sure it will feature the excellent Key Finder 2.0, and be one of the better articles of this year or early next. Keep up the good work.

  • deejdave

    I could be wrong but I do not remember paying for Rekordbox 3, Rekordbox 4 or Serato DJ upon downloading. Also could be wrong but VDJ has a free option as well. Is there money involved in using full capabilities of all of these…….. YES but for the purpose of using as key software these options do not cost a penny more than Keyfinder.

  • sk84l1fe

    which version of mixed in key does their dj software, Flow, use?

    • YV_Miami

      The latest. Flow results will be identical to the newest Mixed In Key results, and will always be updated at the same time as our main algorithms, so it’s also the most accurate key detection software. -Yakov @ Mixed In Key

      • sk84l1fe

        cheers

        • Agungald

          Glad to know someone asked this! I currently analyze my tracks using flow 8 because I got the free demo. But Yakov still gave us the upgrade ! Thanks Sir!
          Anyway I’d really want to buy MIK but got no idea cuz it is online only. My credit card blocked for online transaction because someone used for illegal carding… Any solution?

      • Agungald

        Glad to know someone asked this! I currently analyze my tracks using flow 8 because I got the free demo from the very first version of flow. But Yakov still gave us the upgrade for free ! Thanks Sir!

  • squirrel squirrel squirrel

    One major issue with Mixed In Key that people should remember: it “phones home” whenever you use it. If the software can’t reach the MixedinKey.com server whenever you use it, it will refuse to work and be useless. I have run into multiple occasions where I’ve been cataloging tracks on a plane or somewhere else without wifi before a gig and it flat out refuses to work even though I am a paying customer. So, buyer beware! This is a major issue for traveling DJ’s.

    • Radley

      It also won’t analyze if you have Traktor running. Makes it hard to fix conflicts in the middle of a mix.

    • Dan White

      Great point. I believe Mixed In Key does this to combat software piracy, but it still means that you will require a connection in order to analyze – not ideal for everyone.

      • squirrel squirrel squirrel

        It’s a shame because this cripples the software and harms legitimate paying users without stopping piracy. Traktor, Live, Serato, etc all have copy protection that doesn’t hurt legitimate users in such a detrimental way while being away from internet.

        • djbenetti

          Yeah, it’s absolute bullshit. Especially for a program that you’re much more likely to use when you’re away from the net or in a live situation (e.g. with Traktor). Ever since for this reason I’ve stayed away from their products, which aren’t that good anyway.

          • squirrel squirrel squirrel

            Well, actually I think that Dan White’s analysis shows that their products are that good 😉

          • YV_Miami

            Benetti, we’re #1 in this test, and all the other tests that were done before. That’s not good? -Yakov

          • djbenetti

            Yes, it’s very good indeed that you’re the best in the test, albeit only slightly ahead of Serato (whose software functions perfectly well offline) and others. The point being made here is that it’s often highly impractical for a working DJ who’s paid good money for a legal copy of MIK to have to then connect every time to your server just to detect the key of a song.
            I’m not worried about you looking at my mp3 folders either, you’re most welcome 🙂 but please don’t make me go online every time to run a simple key detection. And that also applies to your otherwise decent Platinum Notes s/w.
            By the way, what I meant by ‘not that good’ was ‘not good enough to justify the extra hassle as stated’, not that they weren’t ‘good’ products. Apologies for the poor choice of wording.

          • davemcl

            Would it be that hard to enable a grace period when no network connection is detected? Or even generate license files using some cryptographic primitive and tie it to the hardware like MAC address and hard drive serial etc?

          • davemcl

            Ah so the analysis is done on the server end so my point is moot.
            FWIW Im a very happy MIK user.

          • Doug

            Yes Yakov, you’re correct…but for how long?
            Serato and Pioneer finally added the function and they offer much more then just key reading…I agree that your software is great and I’ve been using it since version 4 but this function of “ET phone home” is what I really don’t like about it…sure it prevents unauthorized copies, but sometimes you just don’t have access to the internet…

    • YV_Miami

      Yep, I understand the frustration. I’ve had the same feedback from many of the top DJs starting in 2007 when we introduced our first custom algorithm, but the end results are worth it. That’s why we’re #1 in this test and every test before it – the key detection we have is custom-tailored for DJ music and it works like a charm. By the way, the “phone home” thing is just because our key detection runs on a server, NOT because we’re looking at anyone’s music collection. The analysis is anonymous. Nobody on my team including me can see what music you have analyzed, and your actual MP3s are never uploaded online. A good analogy would be that we extract the MIDI from any song, and then upload it online for analysis without uploading the track name. It creates a higher quality result than anyone else in this test. -Yakov @ Mixed In Key

      • squirrel squirrel squirrel

        Interesting that part of the analysis happens on remote servers. Thank you for the insights and great product, Yakov

    • Dan White

      Yep – but that’s why we test it with 66 tracks instead of a handful. The actual percentages might skew on different tests, but we’re still able to establish a good overview of how each algorithm does overall.

      • dibb

        I appreciate the thoroughness of your test, and again, differences between tests are understandable. As a Serato and MIK (5) user I was very curious how SDJ 1.8 would stand up in your test and I’m not disappointed at all. Although SDJ scores 70% against 86% (MIK 6/7) I’ve switched over to SDJ’s key analysis.

        • Dan White

          Remember that there’s also something to be said for internal consistency as well – sticking with one algorithm will likely produce similar RELATIVE results, meaning you’ll still probably get good key mixes out of most of the results. I think this test’s main conclusion is that Rekordbox, Serato, and Mixed In Key are all perfectly solid choices for keying tracks.

          • dibb

            Exactly my thoughts! 😉 That’s why I’ve re-analyzed my complete library with SDJ.

          • deejdave

            Mixed In Key is now an official third party expansion pack for Serato DJ as seen on the Serato website http://serato.com/mixedinkey as well as announced by Yakov (MIK) himself.

            Are we certain the algorithm is not one in the same? The numbers here point to NOT the same yet I too am wondering how an improved algorithm scored a lower percentage this year from last year.

            Also team MIK confirmed that there was a 5% increase in accuracy so I don’t fully understand the MIK 6/7 label as the accuracy should NOT be the same.

          • Dan White

            @disqus_vXNymQShBf:disqus that’s a landing page for Mixed In Key on Serato’s site – it does NOT mean that they use the same algorithm. “support” just means “You can analyze your files in Mixed In Key and get your KEY + ENERGY + CUE POINTS from our software, and see them perfectly inside Serato’s new user interface. Your workflow stays the same: analyze in Mixed In Key > play in Serato”

          • deejdave

            There are certain clues within Serato that would suggest otherwise on a deeper relationship than you suggest. Perhaps using it a bit may shed some light on it. The use of the Camelot system is one huge hint 🙂 Same algorithm? As I said previously the results (not just yours) point to no def a bit more to it.

          • YV_Miami

            Official confirmation: Serato has their own key detection algorithm, and we had nothing to do with it. But, we’re friends with the guys and always respected their work. They know very well how Mixed In Key works, how to help their customers integrate MIK with Serato, and they trust us enough to put us on their store. Serato’s always been a class act, and they have always been great with partnerships, so we’re happy to be featured there. -Yakov @ Mixed In Key

          • Dan White

            Additionally MiK might have confirmed an increase in accuracy, but our results did not indicate that. Results were identical for 7 and 6.

          • Chad Pranke

            The main improvement to the algorithm’s accuracy was in the MIK 5 -> MIK 6 update, as shown in the previous key detection comparison article. 66 songs really isn’t nearly enough to draw any conclusions from when talking about a few percentage points, MIK uses thousands of tracks for testing.

          • YV_Miami

            @disqus_vXNymQShBf:disqus: We updated the algorithm behind the scenes, and pushed the same results to both 6 and 7 at one point. So that probably explains why they are the same – they both got improved over time.

          • Chad Pranke

            “I too am wondering how an improved algorithm scored a lower percentage this year from last year.”

            Which algorithm are you talking about being improved? MIK 6 and 7 use the same algorithm. Serato does not.

        • David De Garie-Lamanque

          i got into the habit of analysing my tunes with MiK, but i also did it with Serato, and the results differ quite often, but when they differ sometimes, i just have to turn one song down or up a semitone for the 2 songs with “matching” keys to work. other times, i just correct the Serato value for the MiK one and it works just fine 🙂

    • YV_Miami

      Music changes every year. If the Beatport Top 100 is full of techno tracks, the key results will be more subjective and harder to lock down. If it’s full of melodic EDM, it’ll be easier. That’s why there’s a percentage difference every year – it really depends on the music you play. Some genres might be almost 100% accurate, some might be a little less.

      • dibb

        Thanks for explaining. Would it be an idea to use the same set of tracks over the years then? Also more mixed genres than Beatport 100 only. Some (hard to analyze) soul/funk, hiphop, pop, etc. We’re not all playing BP Top 100 tracks only, so this would also yield more “real world scenario” results. It’s about testing the algorithms, not the music. Having both of them change makes comparison a bit difficult. Just a thought…

  • deejae snafu

    this is going to wander off topic..

    gratz to MiK for staying on top. with them making other softwares now, i worry about them staying as focused on key detection. i appreciate they want to grow their business, but trying to enter the DJing software market is a super risky use of resources in my humble opinion. its like trying to bring a new cola to market….with coke and pepsi pretty much monopolizing everything in sight, there isnt a lot of room for a new cola, even if its good. this isnt to mention the other field of competitors…

    they should instead consider marketing MiK to producers, and budding instrumental musicians ….and other ways to improve the algorithm itself to make sure MiK stays king of detection.

    • YV_Miami

      Thanks man. We never want to compete against Traktor and Serato because 1) we respect what they do and know them personally, and 2) we can’t do better than them and we don’t want to. Our software always carves a unique niche. With apps like Flow 8 Deck (www.flow8deck.com), we want to focus on the Ableton Live fans who want to play complex DJ sets.

      Our next product called Odesi will be announced and launched very soon – and it’s actually designed for producers and instrumental musicians. We’re a small team so it’s hard to do everything at once, but Odesi was worth the wait. Watch DJ Tech Tools for more on that.

  • Agos

    I was waiting for this article! Thank you very much! Very very interesting as always! My go-to is still KeyFinder as it’s such a good program and it’s free! But I’m tempted from the good performance of Serato. I own a DDJ-SB so it will be a natural upgrade from Dj Intro, but it bothers me not having full mapping capabilities. I know it has been added a remapping function but It’s nowhere near the Traktor capabilities. I’m bothered that Traktor doesn’t improve a bit given that its key detetion functions are tightly integrated.

    • Dan White

      You’re very welcome – we’re waiting on details about the next release of Keyfinder and if it has the potential to be a winner. Obviously we like free as well! 🙂

      • deejdave

        Keyfinder 2.0 will be Mac only correct?

          Yeah, that’s right. I’ve decided to stop pretending that I know anything about Windows!

      • Ibrahim Sha'ath

        Dan, did you get a chance to look at the build I sent you a few weeks back?

      Please note that you’ll get Serato’s key detection feature for free as well. This feature is supported in the freely downloadable (offline) version of SDJ 1.8.

    Great overview – I am following these comparisons now for a couple of years already.

    What would be interesting: an article on how to best use Traktor with Mixed in Key. I am still a bit confused about how Traktor treats / uses the MiK information.

    • Agos

      You’re right! It’s very confusing how Traktor uses external detected keys! (not only with MiK) Sometimes when I load a track it overrides the already detected key with its own detected.

      • Simon H

        Good solution I use is to use Traktor to analyse its own key , then use keyfinder as a cross check and write the key from keyfinder to the comments field on the tag, then in Traktor you can see both to get a reference on potential variations.

    If you guys have other softwares you would like me to test, please reply here and let me know. These were the most-requested ones for this style of roundup.

        They use KeyFinder (v1 I think)

      djay Pro (Mac) / djay 2 (iOS)
      (pretty sure they use the same key detection on both platforms)

      This may be a little silly, but i use a little Chrome extension called “TrackCheck for SoundCloud” which analyzes tracks on SoundCloud. It’s super useful for when I download free tracks so can I tag them right away, but I always wondered how good it’s the detection algorithm.
