The audio titled "Convert the A to D using the Flange Method" begins with the strumming of an electric guitar playing the A chord. The method of conversion, known as the Flange Method, is then explained and demonstrated. The audio guides the listener through the process of transitioning from the A chord to the D chord on a guitar. This is done using a flange effect, which is a technique that involves bending the pitch to create a 'spacey' or 'nasty' sound. This effect is commonly used in electric guitar riffs to add richness and depth to the music. As the audio progresses, the electric guitar continues to play, demonstrating the various notes within the A and D chords. The strumming pattern changes to mimic the flange effect, which is clearly heard as a fluctuating pitch that adds a unique texture to the standard chords. By the end of the audio, listeners should have a clear understanding of how to use the Flange Method
