New open source key detection tool
New open source key detection tool Posted on: 30.09.2011 by Kari Spindel Hey all,I just finished a computer science course and built a key detection tool for DJs as my final project. The tool is called KeyFinder. It's designed to work primarily with EDM, but it's highly tweakable and I've had decent results with various genres. In addition to a batch key detection interface which can write to metadata tags, it includes a musical visualisation tool called a chromagram. I've found this quite useful for visualising chord structures, melodies and key changes, and I believe it's pretty unique in the DJ software world; I haven't seen any other tools that have something similar. I got good accuracy during my experiments but unfortunately I didn't test it on a wide selection of music. I had very little time and had to key it all manually and then get the results verified. It would be great to improve KeyFinder to work on a wide variety of genres. So I'm releasing it for free under the GPL, in the hope the community finds it useful. It's a bit primitive, and for Mac only at present, but it should be pretty simple to port to Windows if there's interest. If you want to try it you can download a Mac binary here. My write-up which describes the algorithms is also there if you're into that kind of thing. If anyone has any interest in working on it, or any comments or questions, feel free to get in touch here or using the email address on that page. Cheers | |
| Brunilda Kora 12.09.2013 | No, But, the truth is, if you cannot tell if 2 tracks are key clashing using your ears, does it mater if the software you use isn't 100% accurate anyway? |
| Season Bergere 12.09.2013 | Thanks for the free program. I tried it and it works fine as far as I can tell. My question is how accurate is it compared to other programs, I checked your http://ibrahimshaath.co.uk/keyfinder/comparison.pdf but I don't understand the comparison test. Is there any program that will get it 100% right all the time (not saying yours doesn't)? |
| Random X 11.09.2013 | Ooh yeah! |
| Latoria Kavulich 10.09.2013 | 30 tracks in 5 mins. Boom |

| Kari Spindel 04.09.2013 | New version 1.24 is up It fixes a tagging crash on WAV files, adds a load of tests for tagging so fewer issues should appear in future, and includes some new localisations. Enjoy! |
| Kari Spindel 06.08.2013 | Version 1.23 is up. It includes the option to filter batch jobs by file extension, which has been requested a few times. It also fixes a few tagging bugs. Enjoy. |

It includes a fix for a fairly serious batch crash (sorry about that one), improved behaviour for Serato libraries on secondary Mac volumes, and some UI bugs. Also, Mac localisations now obey the Language settings as opposed to Region. I'm afraid I missed all the messages here since last week; DJTT seems to have stopped notifying me of new posts. So, a quick set of responses: xerorane: I'm not going to be supporting Mavericks until after launch, sorry. If you can't donate via the Paypal button on the site, you could consider buying some music at the bandcamp site in my sig. niknok: 1: you're welcome. 2: it works here; have you tried right-clicking and using the option from the context menu? 3: that's fixed in this release. slayformoney: I just fixed this language issue on Mac but Windows is less flexible. Can you let me know how all your language/location stuff is set up in Windows? Are your language and localisation settings consistent? |
| Latoria Kavulich 19.07.2013 | 1.21 working perfect here mate. |
| Isa Erik 17.07.2013 | tried 1.21 on winXP SP3 - works with no problem, loads faster had a problem with language (don't like using my native language on PC) so I had no other option but to delete all language files but the ENG one |
| Pierre Massner 17.07.2013 | If you have a Japan Paypal acct you can't donate..go figure...look at the reply my comment on the same problem above and you can buy something from Bandcamp instead. 3 things with new version 1.21 1. append key to track title tag - already! thank you so much! 2. select a track in KF and hit delete/backspace doesn't seem to delete rfom the list 3. dropping folders onto KF seems to work but if there's anything other than audio files in the folder KF crashes when I hit run batch analysis. OSX 10.6.8 thanks again Ib |
| Mozella Valinski 15.07.2013 | also where can I donate? |
| Mozella Valinski 15.07.2013 | Hello I decided to be an early adopter to OSX mavericks now i'm having an issue when launching Keyfinder 1.21 it automatically crashes I also have v1.16 that runs fine but when I try to go onto Preferences nothing happens I can't edit any information for Keyfinder. Just wanted to give you a heads up. Process: KeyFinder [8245] Path: /Applications/KeyFinder 1.21.app/Contents/MacOS/KeyFinder Identifier: com.yourcompany.KeyFinder Version: ???

| Kari Spindel 14.07.2013 | v1.21 is up It fixes a few memory leaks, and a bug with the cmd+comma sequence on Mac localisations. Everything else is background stuff to make my life easier, and will hopefully lead to fewer bugs in the future =) |
| Kari Spindel 06.07.2013 | KeyFinder 1.20 is now available. This version allows you to write to the Title, Artist and Album tags, which has often been requested, though I do not know why =) It also fixes the frame rate exception with video files, and should no longer corrupt mp4 tags. |

| Kari Spindel 05.07.2013 | Anyone who had an immediate crash from yesterday's Windows build, please try downloading again, I've added some missed dependencies to the package. Works on all my Windows boxes now. |
| Latoria Kavulich 04.07.2013 | Sweet! will do some testing and get back to you for the windows version |
| Kari Spindel 03.07.2013 | Right, here are two things I didn't expect to be saying quite so soon: * KeyFinder 1.19 is now available. It's just a patch release, I found a weird bug with certain decoders. * After many, many hours of poking and prodding, it's available for Windows, sort of. As always, I can't guarantee complete compatibility, or even that it'll work on your machine. It doesn't work on my old XP laptop. But hopefully it's better than nothing; give it a try and see how you get on. |
| Kari Spindel 03.07.2013 | Thanks man, much appreciated |
| Pierre Massner 02.07.2013 | Thanks, O Fortuna bought just now. |

| Pierre Massner 01.07.2013 | Key tags in flacs - fantastic! That's one less process to my process. Thanks so much always for your work, very much appreciate your way of doing things....I just tried donating again but PPal doesn't support donations from Japan...wtf? Anyways, not for want of trying and of course purely personally motivated, one relatively straightforward feature I'd love to see would be the ability to append key info to the end of the track name tag rather than only the file name and key tag, reason being that in Traktor I always look at the track name for key info on current playing track before using the key tag column in the browser for possible next tracks - the current track is always in a fixed location so having current key there is a great help. Another advantage is that when converting files to use in another format/app ie Djay on the iPad, as there's no key tag available there that I currently know of, so having it simply appended to the track name would be a great start, even if track lists aren't searchable by tag. Make sense? Thanks again and if there's a way I can donate I will. |
| Latoria Kavulich 29.06.2013 | Dang. Gotta admit, kinda gutted there are no plans to continue the windows versions, been using this since you released it and been very happy with it. Still, at least 1.17 works perfectly for me |
| Isa Erik 29.06.2013 | glad to hear that |
| Kari Spindel 29.06.2013 | Hey hey. Very sorry for the long silence, but the new version 1.18 is now available, for Mac only. This includes: * a slightly faster analysis process, with a much, much smaller memory footprint; it should be easier to run KF alongside other apps now (although it's still very CPU intensive, obviously) * a hack for the key tag in FLAC files, using the de facto standard among DJ apps * the preservation of ID3 v2.3 tags, rather than automatically upgrading them to v2.4 * lots of new localisations * a load of bug fixes and minor new features. The delay has been largely due to my working with a DJ software house to integrate the KeyFinder algorithm into their packages. The upside of this means that all the improvements I've made for them get passed on to you! Also... this release is not for Windows. I still haven't got the time or the interest to do the Windows work, so it may be a long time coming unless a Windows dev steps up to help out. Sorry about that. All intelligent feedback gratefully received. |
| Alfreda Muenster 01.06.2013 | Just installed this on Windows 8, 64-bit, can't drag and drop audio files into window for analysis? Is there a write up for a how to use guide? |
| Dani Gutsche 22.05.2013 | Likewise, thanks! |
| Valentina Joline 04.04.2013 | Awesome, was very helpfull for me! cheers |
| Rolando Chriss 15.03.2013 | Hi guys, I did this little translation of the key codes for Keyfinder, so you can use the famous Camelot Key codes from other key detection softwares to match your songs! Hope can be useful, bye keyfinder.JPG |

It's much better in my opinion than the Rapid Evolution and a few programs I tested before them. I use it all the time, but I'm not sure will I use it when I get a hold of Traktor 2.6.1 version. Anyway, if you need some help with coding it, I'm your guy! Hit me up at [email protected] and I'll be honored to help you out or be a tester or something (I'm a Windows user, I have Windows 7 x64 Ultimate version on a laptop, Windows XP x86 Service Pack 3 on my desktop and I have Ubuntu 12 installed on my desktop as well but I don't use it frequently). Pretty good with Visual Basic, Delphi and HTML/CSS/PHP (in case you need some fancy website or something). Also pretty good with Pascal and Basic, but that won't be very useful to you I guess. Solid in C and C++ programming. |
