Delay is an essential tool in the audio engineer’s toolkit, offering a way to add depth, texture, and dimension to vocal tracks. When used correctly, delay can transform a flat, uninspiring vocal into a rich, engaging performance. Here are five quick tips to help you master the art of using delay on vocals.
1. Choose the Right Delay Time
The delay time, measured in milliseconds, determines how quickly the delayed signal follows the original vocal. Here’s a simple guide to selecting the right delay time:
• Short Delays (50-100ms): These can add a subtle thickness and richness to the vocal without being noticeable as an echo.
• Medium Delays (100-300ms): These create a more pronounced echo effect, which can add a sense of space and depth to the vocal.
• Long Delays (300ms and above): These are often used for special effects, creating distinct echoes that can add drama and interest to certain vocal lines.
Experiment with different delay times to see what fits your track best.
2. Sync Delay to the Song’s Tempo
Most delay plugins and hardware units offer a tempo sync feature. By syncing the delay to the tempo of your track, you ensure that the echoes fall in time with the music, which helps maintain the groove and rhythm. This is particularly useful for rhythmic delays where the echo repeats are designed to complement the beat.
3. Use Feedback Wisely
Feedback controls how many times the delay repeats. Here’s how to use it effectively:
• Low Feedback (1-3 repeats): Adds a sense of space without cluttering the mix.
• Medium Feedback (4-6 repeats): Creates a more noticeable echo, which can enhance specific vocal phrases or add a dreamy quality.
• High Feedback (7+ repeats): Can create a cascading effect, ideal for experimental or psychedelic tracks.
Be careful with high feedback settings as they can quickly overwhelm your mix if not used judiciously.
4. Apply EQ to the Delay
Using EQ on the delayed signal helps to avoid frequency buildup and keeps the delay from muddying your mix. Common EQ strategies include:
• High-Pass Filter: Cuts low frequencies from the delayed signal to prevent bass buildup.
• Low-Pass Filter: Reduces high frequencies to create a warmer, more vintage-sounding delay.
• Mid-Range Scoop: Reduces certain mid frequencies to make the delay sit better in the mix without competing with the original vocal.
5. Automate for Dynamic Effects
Automation allows you to change the delay settings dynamically throughout your track, adding interest and variation. Some ways to use automation include:
• Delay Throws: Automate the send level to the delay so that only specific words or phrases are affected, creating a dramatic echo effect at key moments.
• Feedback Changes: Increase feedback during certain sections for a more intense echo effect and reduce it during verses for clarity.
• Delay Time Modulation: Change the delay time slightly during different sections to add a sense of movement and evolution to the vocal.
• Panning: Automate the delay’s panning to introduce intriguing movement within your mix.
Conclusion
Using delay on vocals is a powerful way to add depth, character, and dimension to your tracks. By choosing the right delay time, syncing to the tempo, using feedback wisely, applying EQ, and automating for dynamic effects, you can create professional-sounding vocal tracks that stand out. Remember, the key to using delay effectively is subtlety and taste. Less can often be more when it comes to creating a polished and engaging mix.
