Publisher's Description

Chordec does chord recognition for songs from your iOS device. Its algorithm accuracy is among the highest published algorithm accuracies till at least the end of 2012.
*Note: Chordec cannot load DRM encrypted music and it may lead to a crash of the app.

Chord recognition accuracy under default "chordec sensitivity":
80% if counting only major and minor chords,
65% if counting only maj, min, aug, dim, 7, maj7 and min7

Load a song from your iOS device, and chordec solves the chord for you. You can then learn the chord using the speed-variable playback. Can't figure out how to rewind or fast forward? Move the cursor or scroll/zoom the tape to navigate to anywhere in the song.

You may also tweak the sensitivity of chordec to get the right chord complexity for the song or for yourself. Generally, the more maj7/min7/aug/dim the song might contain, the higher the sensitivity should be set to.
