How does automating the wet/dry ratio of a delay effect on vocals create a dynamic and engaging effect?

Automating the wet/dry ratio of a delay effect on vocals creates a dynamic and engaging effect by varying the prominence of the delay over time. The wet/dry ratio controls the balance between the original, unprocessed vocal signal (dry) and the delayed signal (wet). By automating this ratio, you can make the delay more or less noticeable at different points in the song, adding movement and interest to the vocal performance. A common technique is to increase the wet signal (more delay) during the ends of phrases or on specific words to emphasize them and create a sense of space and depth. Conversely, you might reduce the wet signal (less delay) during busier sections of the song to maintain clarity and prevent the delay from becoming overwhelming. This automation can be used to create a push-and-pull effect, drawing the listener's attention to certain parts of the vocal while allowing other parts to remain more grounded and intimate. For example, if a vocalist sings a particularly powerful or emotional line, increasing the delay on that line can amplify its impact and create a more dramatic moment. Conversely, decreasing the delay on a more subtle or understated line can help it blend seamlessly into the mix. Automating the wet/dry ratio allows you to use delay as a creative tool to shape the dynamics and emotional impact of the vocal performance, rather than simply applying a static effect.
