Creating Chord Events from Audio Events

You can extract chords from audio events. This is useful if you have an audio file and want to show its harmonic structure, and use this file as starting point for further experimenting.

Prerequisite

  • You have added a chord track.

  • On an audio track, you have added an audio event with audio material that can be interpreted as chords, that is, with three or four different note pitches playing simultaneously. The audio material should contain western music with 12 pitches per octave, tuned in equal temperament.

Procedure

  1. In the Project window, select an audio event on an audio track.
    Note

    You cannot use audio parts.

  2. Do one of the following:
    • Drag the audio event and drop it on the chord track.

    • Right-click an audio event, and select Create Chord Events from the context menu.

    • Select Project > Chord Track > Create Chord Events.

Result

  • The chord events are added to the chord track. Depending on the length of the audio event, this may take a while.

  • The chord events that you created from audio events are indicated by a symbol in the upper right corner.

  • The created chord events match the positions and lengths of the corresponding chords in the audio event.

  • If the chord track already contained chord events, these are replaced within the position and length of the audio event. Chord events outside that range will be kept.
