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) email: feedback@chord-detector.com www: http://www.chord-detector.com twitter: http://twitter.com/chorddetector fb: http://facebook.com/chorddetector
