Essential Vocal Effects You Need to Know as a Music Producer

Introduction

Voice effects are key tools for any music producer aiming to elevate vocal tracks to a professional level. We asked our Musiversal experts to help us create this guide, covering the most widely used voice effects, explaining how they work, and offering practical tips for their application. Whether you're an experienced producer or just starting out, understanding these effects will help you enhance your vocal recordings effectively.

‍EQ (Equalization)‍

What Is An EQ?

EQ stands for equalization, which is the process of adjusting the balance between different frequency components within an audio signal. Equalization tools enable you to isolate specific frequencies in an audio file, eliminating unwanted sounds or amplifying the frequencies you wish to emphasize.

Types of EQs

‍ Dynamic EQ:

Parametric EQ:

Graphic EQ:

‍ Digital vs. Analog EQs: Digital and analog EQs can produce subtly different sounds. Digital EQs offer precision and repeatability, while analog EQs often impart a certain character or warmth to the audio signal.

How Can You Use an EQ?

Understanding how to effectively use an EQ involves applying various filters to either boost or cut specific frequencies. Here’s a breakdown of methods for using parametric, graphic, or dynamic EQs on vocals or across the entire frequency range of a track:

‍Subtractive and Additive EQ

Creative Filtering: EQ can also be used creatively, beyond technical adjustments. For instance, automating dynamic EQs to create custom filters can add interest and variation to your tracks.

Compression‍

What is Audio Compression?

Compression reduces the dynamic range of an audio signal. Vocal recordings naturally have a wide range of loud and soft parts, making them dynamic. Compression narrows this range, making the volume more consistent throughout. This results in the vocal sounding louder and more present in the mix without the loud parts peaking or the quiet parts getting lost. ‍

Common Uses for Vocal Compression

Compression is essential for vocals (or any part of your mix) that need dynamic control. The amount of compression used depends on the performance style and music genre.

If you're unsure how much compression to use, listen to a reference track in a similar genre. Analyze the vocal dynamics: if there are minimal changes, it's heavily compressed; if you can hear subtle dynamic variations, less compression is used.

Step-by-Step Guide to Setting Up a Compressor‍

By understanding and applying these principles, you can effectively use compression to enhance your vocal recordings and achieve a professional sound in any genre.

‍Reverb‍

‍What is Vocal Reverb?

Reverb is a time-based effect used to simulate the sound of sound waves reflecting off surfaces like walls, objects, or the floor. If you've ever noticed your voice sounding different in a large space like a church compared to a smaller room, that's due to the natural reverb characteristics of those environments. Reverb effects and plugins replicate this phenomenon in audio production, and they are commonly used across various genres on lead vocals, backing vocals, lead instruments, and more.

Components of Reverb

Every reverb effect comes with controls that allow you to shape different sonic atmospheres for your audio signal. Here’s an overview of the essential reverb settings:

Types of Vocal Reverb

Different types of reverb add unique characteristics to vocals:

Should Vocals Be Recorded With Reverb?

Unless capturing the natural reverb of a space, it’s best to record vocals dry (without effects). This approach gives you full control over the balance between the clean vocal and the processed signal during mixing.

Here is a great video that shows you different ways in which reverb can be used to enhance your vocals: ‍

How Much Reverb is Good for Vocals?

The amount of reverb depends on the context and genre of the vocal. Different reverb types will affect the signal uniquely. For instance, genres that call for a natural sound might use minimal reverb, while genres like shoegaze rely heavily on spacious reverb effects.

Tips for Using Vocal Reverb‍

Delay‍

What is Vocal Delay?

Vocal delay is an audio effect that repeats the vocal signal after a specified period, creating an echo-like effect. By delaying the vocal track, you can add depth, space, and rhythmic complexity to your mix. Unlike reverb, which simulates the natural reflections of sound in a space, delay creates distinct, repeated echoes that can be precisely timed to enhance various aspects of the vocal performance.

Key Parameters of Delay‍

Practical Uses for Vocal Delay‍

Delays can transform vocals, adding depth and rhythmic interest. They can accent hooks, fill silences, and enhance grooves. The key to using delays effectively is to experiment. Don’t use a delay just because it’s recommended; listen to how it interacts with your vocals and the rest of your mix. Sometimes, combining several delays or using both reverb and delay can yield the best results. Don’t be afraid to try new things and find what works best for your track.

Chorus‍

What is the Chorus Effect?

Chorus is an audio phenomenon that occurs when multiple similar sounds are heard simultaneously, like the massed voices of a choir or the rich, sparkling sound of a string orchestra. These similar sounds blend into one, creating a distinctive, shimmering quality that is pleasing to the ear.

In music production, the chorus effect emulates this sound using studio techniques. By duplicating a sound and altering the copies in subtle ways, it creates the impression of hearing multiple"voices"at once. This adds thickness and sparkle to the original sound, making it seem larger and more vibrant.

‍How Do You Get the Chorus Effect?

The chorus effect works by copying a signal and delaying this copy by a small amount (around 15–35 milliseconds). An LFO (low-frequency oscillator) changes the delay time over time, also altering the pitch of the copied signal, making it slightly out of tune with the original. The processed signal is then recombined with the original, creating the illusion of multiple instruments or voices playing together.

When the dry and processed signals combine, they produce a distinctive shimmering effect due to phase interference between the two signals. This phase relationship changes from moment to moment, creating the characteristic chorus sound.

The Difference Between Chorus, Flanger, and Phaser

Chorus is often confused with flanger and phaser effects. While they have similar sounds and are used in similar contexts, they differ in their technical implementation:

Check out this video to hear what chorus, flanger and phaser sound like:

Famous Songs Using the Chorus Effect

Chorus has been a staple in music production for decades, especially on guitars but also on other instruments:

Chorus Parameters

Understanding and mastering the basic parameters of chorus plugins will help you achieve the desired sound:

How to Use the Chorus Effect

Chorus can serve your productions in numerous ways. It can add depth and ambience to pads or atmospheric sounds, thicken up vocals, or widen the stereo image. However, it's easy to overdo it. A chorus effect that sounds exciting at first might become tiring on the ear. Use the mix knob to blend the chorus effect back into your dry signal for a more balanced sound.

Applying Chorus to Vocals

Chorus can enhance vocals by thickening a lead vocal or pushing backing vocals to the sides of the stereo field. Use subtle settings for lead vocals and more extreme settings for backing parts to create space and depth.

Now that you know what chorus is, how it works, and how it has been used in music, you can start applying it to your productions. Chorus can add depth, width, and character to your tracks, making them more engaging and immersive. Experiment with different settings and applications to find the perfect chorus effect for your music.

Vocal De-Esser‍

‍What is Vocal De-Esser?

De-essing is the process of reducing the volume of sibilance (s’s and t’s, or “esses”) in a vocal recording. A de-esser is a frequency-dependent compressor that identifies the frequencies where sibilance occurs and reduces them once they exceed a specified threshold.

Sibilance is the bright, high-frequency sound caused by certain consonants like s’s, t’s, d’s, and z’s during speaking, rapping, or singing. The frequency range of sibilance varies for each voice, influenced by factors such as language, dialect, and accent. Harsh sibilance can result from the microphone type, EQ settings boosting the brightness or high-mids of a vocal, or the natural sound of the vocalist’s esses. ‍

Why Do You Need a De-esser?

A de-esser is crucial for taming loud and prominent sibilance, making the vocal less harsh and more pleasant for listeners. Many professional recordings feature a de-esser somewhere in the vocal chain. However, not every vocal recording requires a de-esser. Overly harsh sibilance might not occur with every vocalist. Trust your ears to decide whether a de-esser is necessary. If sibilance is bothering you, especially when mixing on headphones, try using a de-esser.

Key Parameters of a De-esser

De-essers have straightforward parameters, but it takes experimentation and a tuned ear to use them effectively. ‍

Watch this video to see how de-essing vocals works: ‍

How to Use a De-esser Plugin

Using a plugin is the easiest way to de-ess. Loop a section of the vocal where the esses are most prominent. Use the “listen” function or your ear to set the target frequency. Adjust the threshold to set the de-esser’s sensitivity and the max reduction if needed. Listen back both in solo and in the context of the mix, and tweak accordingly.

Where to Put a De-esser in the Effects Chain

The placement of a de-esser in the vocal chain is often debated, but it’s generally recommended to place it before a compressor and after an EQ. Since de-essers use dynamic changes to identify sibilance, a compressed vocal might make it harder for the de-esser to work. If you’re adding brightness with an EQ, the de-esser should account for that when reducing sibilance.

If a single de-esser doesn’t catch all the sibilances, consider automating it. It’s rare for one de-esser to handle all sibilances in a vocal performance, so automation ensures that every harsh ess is addressed.

‍Should You De-ess Manually?

Some producers and engineers prefer to manually reduce sibilance due to its unpredictable nature. This involves identifying harsh sibilance in the waveform, cutting the audio, and reducing the volume with clip gain or a similar process. While time-consuming, this method allows for a more customized and thorough result.

De-essing is a critical step in vocal production. By understanding how to use a de-esser effectively, you can ensure your vocals are smooth, clear, and free of harsh sibilance, resulting in a more polished and professional sound.

Pitch Correction‍

What is Pitch Correction?

Pitch correction is the process of fixing notes that are out of tune. This is achieved in two primary ways, depending on the plugin used. The first method involves analyzing the incoming pitch, determining if it is too low (flat) or too high (sharp), and automatically adjusting the pitch to be centered on the correct note. This is how plugins like Auto-Tune and Nectar 4 operate, typically processing the entire track as a global effect.

The second method allows for more detailed control by enabling the user to adjust notes individually. This note-by-note adjustment is how Melodyne operates, providing a more fine-tuned approach rather than a broad, global effect.

The method you choose will depend on the singer’s performance and your goals for pitch correction. Understanding how pitch is measured is also crucial. Pitch is measured in cents and semitones, where 100 cents make up one semitone, the equivalent of a half step on a piano. ‍

Ways to Use Pitch Correction

Pitch correction can be used in various ways. Often, you won't even notice its subtle application to fix a note or two in a performance. However, genres like pop and hip hop frequently use heavy pitch correction as a vocal effect. You can also use pitch correction creatively, such as copying a vocal track, tuning one copy, and leaving the other un-tuned to create a double track. Additionally, pitch correction can quickly create vocal harmonies.

While this tutorial focuses on vocals, pitch correction can be applied to other instruments as well, including bass, horns, and strings. Most techniques for vocal pitch correction will work for almost any monophonic source, so feel free to experiment with various sounds, even drum samples!

How to Use Pitch Correction on Vocals

Tuning vocals is one of the first steps in making your vocals sound professionally mixed. Typically, pitch correction should be the first insert on a track, before any EQ or compression. This is important because, in plugins like Melodyne, you transfer your vocal track’s audio into the plugin. If EQ or compression is applied before pitch correction, those effects will also transfer, requiring rework if you change settings later.

Nectar operates differently, so plugin order is less critical. However, I prefer to EQ the tuned vocal, especially for creative applications, because the tuner can add its own EQ curve that may need adjustment to fit the mix.

Common Questions About Pitch Correction‍

Using pitch correction can help your music sound polished and professional, ensuring every note is perfectly in tune while also offering creative possibilities to enhance your sound.

Saturation‍

What is Saturation?

Audio saturation adds warmth and richness to your recordings by mimicking the pleasant distortions that happened with old analog equipment. When audio is pushed too hard, it creates extra harmonics and gently compresses the sound, making it fuller and more pleasing. Today, we use digital plugins to recreate these effects.

Types of Audio Saturation‍

Even and Odd Harmonics‍

Check out this video to hear how vocal saturation works: ‍

Saturation vs. Distortion

Saturation is a subtle form of distortion that enhances audio by adding warmth and richness. While all distortion alters the shape of the audio waveform, saturation specifically adds harmonic content and soft compression. Other types of distortion, like digital distortion, can be harsher and less pleasant to the ear.

Benefits of Using Saturation on Vocals‍

How to Use Saturation on Vocals‍

Should You Always Apply Saturation on Vocals?

While saturation can add warmth and depth to vocals, it’s not always necessary. If your vocals were recorded with high-end analog gear, additional saturation might not be needed. However, for clean digital recordings, saturation can significantly enhance the vocal sound. Use it wisely to avoid over-saturating and muddying the mix.

By experimenting with different types and settings of saturation, you can transform your vocals, making them richer, fuller, and more engaging. Whether you’re aiming for a classic analog warmth or a modern, punchy sound, saturation can be a powerful tool in your vocal production toolkit.

Vocal Doubling‍

What is Vocal Doubling?

Vocal doubling is a recording technique used to add richness and texture to vocals. By layering multiple vocal takes over each other, you create a fuller sound that helps the singer stand out in a mix. This effect can be achieved naturally by recording the same part multiple times or by using a vocal doubler plugin.

Using a Vocal Doubler

While recording multiple vocal takes can produce excellent results, using a vocal doubler plugin is a great alternative, especially when working on a tight deadline or when a more processed sound is desired. Vocal doubler plugins can emulate the effect of double tracking without needing the singer to perform multiple takes. These tools provide a professional sound quickly and efficiently. Watch this video to hear what they sound like: ‍

How Vocal Doublers Work

Vocal doublers create the illusion of multiple vocal performances by taking a single vocal track and replicating it. The duplicate is then slightly altered in time and pitch to mimic the natural variations of multiple takes. Here’s a simple breakdown of the process:

Practical Tips for Using Vocal Doublers

‍ Achieving the Best Doubled Effect:

Slight timing and pitch discrepancies enhance the doubled effect, giving a sense of thicker vocals without sounding unnatural.

‍ Integrating with Virtual Instruments:

Blend seamlessly by adjusting the level of your doubled vocals to complement the virtual instruments. Apply EQ cuts to virtual instruments and boosts to vocals as needed to ensure they sit well together.

Vocal Transient Shaper‍

What is Transient Shaping?

Transient shaping is an audio processing technique used to manipulate the attack and sustain characteristics of an audio signal. While it is commonly used on percussive elements like drums, it is also highly effective on vocals to enhance their clarity and presence in a mix. By adjusting the transients, you can make a vocal track sound punchier and more defined, helping it cut through the mix.

How Transient Shaping Works

Transient shapers work by detecting the transient elements (the initial, sharp parts of a sound) and allowing you to adjust their levels independently of the rest of the signal. This manipulation can enhance or soften the attack of a vocal, as well as control the sustain (the tail end of the sound).
