Chord Detector is an app that will analyse audio sources and automatically detect the musical chords within it.

With Chord Detector you can learn to play any track in your devices music library or Dropbox folder providing its not DRM encoded.

Chord Detector can also analyse and detect the chords within a YouTube video or a SoundCloud sound.

Chord Detector is aimed at musicians of any ability to help you learn to play many more songs, especially those whose chords arent readily available on the internet.

Please note that iTunes Match and Apple Music is not supported due to technical constraints.

With our update Chord Detection engine its now much quiker and easier to get most accurate results possible (up to 95% in ideal conditions). Chord Detector can recognise many different chord types including major, minor, augmented, dimimished, diminished7, dominant7 and minorMajor7.

To get started just pick one of the four audio source options:

● iPod Music Library
● Dropbox
● YouTube
● SoundCloud

You can then select any track from your iPod Music Library(†), Dropbox folder, select a YouTube video or a SoundCloud sound. Chord Detector will then analyse the selected music source and within minutes (if not quicker) you will be presented with a view of the detected chords containing within that music source.

You have the option to view the detected chords in two different forms, scrolling and tabular. In both of these views you are able to play the track and the chords will move or be highlighted as the song is playing.

You can now start to view the chords of a track when analysis is still ongoing. Also you can queue up tracks to be processed, so while you are learning to play one song the chords are being generated for your other tracks in the background.

The following controls are available on the chord view screens:-

● Play/Pause - play or pause the track.
● Rewind 30s - rewind the track by 30 seconds.
● Forward 30s - forward the track by 30 seconds.
● Tempo Adj. - slow down the track without affecting the pitch by a variable amount down to 1/4 of its original speed.
● Capo Adj. - transpose the chords according to which fret you want your capo on

Now ukulele, banjo and mandolin chord diagrams are available via an in-app purchase.

† The following audio file formats are supported, MP3, AAC, WAV and AIFF. DRM protected content is not supported. Tracks must by syncd to your device. If you use iTunes Match you must ensure that the track you wish to use in Chord Detector is first downloaded to your device (otherwise you may see a DRM warning)

Pros and cons of The Chord Detector app for iPhone and iPad

The Chord Detector app good for

.... But random performance. Chords are recognized at about 50%, and unfortunately the app doesnt allow you (yet) to edit the missing or wrong chords. An export function would be a great add-on to, and possibilities to search the library or filter via other criteria than song name. And it works fine on iPad but for know only in "double" iPhone screen. Keep on with the good work!
Really nice app.... really accurate on the chords.... totally the new guitarist best friend!
I had some songs my kids love and I could not find the chords anywhere on the net... Im not really good at finding the chords just by listening to a song... This app is wonderful! It works fine and customer service is incredible! This saved me a lot of time and money! A great investment!
In 4 years, Ive never written a review. Until now. I found this app on a whim, took a chance in downloading it and am very pleased indeed! The real-time note-by-note transcription and the ability to slow down the song with no variance in the pitch will be invaluable to my learning. Much appreciated on a job well done!
Ive been buying several music apps over a two year period now... THIS ONE IS THE BEST!!!!! Thank you so much!
Holy #%%%# this is every musicians dream !! I have a show coming up and we are learning a bunch of covers.. This app saved me the terrible task of finding a lagit or learning it by ear. Thanks much !!!! Ive been waiting for this sorta software for years!

Some bad moments

This app Works prety well but I dont see any export facility on the web site or on the cloud.
This app is horrible. I uploaded two songs and it got it so wrong. It cant tell the difference between a Gm and a Gmaj9?! Its useless. Maybe its one for those simple 3 or 4 major chord songs but this apps practical usefulness is horrible. I wish I could get my money back.
This app is terrible, it does not have anything more than generic chords. I took a song I knew incredibly well and it was entirely wrong. It would not pick out the fact that it was a cadd9 chord or anything more than major minor chords. This app is not worth your money, it doesnt do what it says it does.
I have just bought it, after i installed it, it did not work , restarted the ipad , same problem , i click on the icon but the program does not run ,,,
Cool idea, but needs to do a better job of catching all of the changes without skipping any or falling behind.
This app is horribly buggy and not worth the 2.99 paid for it. It doesnt even support microphone input. Deleted almost immediately.
