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 aren't 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 sync'd 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)

How cool is this?

Would be 5 stars but unfortunately it can't cope with DRM protected tracks and some of my favourite songs I was hoping to use are protected this way. However, this is very cool and I have spent all afternoon converting some of my favourite tunes. I am a beginner with the guitar but was amazed at how simple this is and I'm now playing a bit of pink flood like a pro, well, almost!. One other gripe is that you can only search your iTunes by track, which is a bit of a bind. Admins, please update so I can search by artist. In all a great and clever app for 69p

Great idea

Really seems to work. Throws in a few spurious chords every now and then at a chord transition point (although if you could play those passing chords quick enough they would probably be in tune) but apart from that, really pleased to be able to get the chords quickly to my favourite songs. Thanks for making it.

Very good

Especially because it lets you put a capo on different frets and hence shows easier ways of playing a song. Have tested with 4 songs so far, the chords for all of which this program successfully detected. £1.99 very well spent compared to similar and much more pricy PC equivalents with which I've had less success determining correct chords. Thank you for this software as it's really a great aid in learning guitar and learning songs.
