Understanding the Role of Vocals in a Mix

The Purpose of Vocals in Different Genres

Vocals are often the centerpiece of a song, acting as the primary vehicle for the song’s message and emotional expression. In genres like pop, rock, and R&B, the vocals are typically the focal point, requiring a clear and upfront presence. In contrast, in genres such as electronic dance music (EDM) or ambient, vocals may serve more as an atmospheric element, blending with the instrumental layers. Understanding the role that vocals play in your specific genre is crucial to mixing them effectively.

How Vocals Interact with Other Elements in a Dense Mix

In a dense mix, numerous elements compete for space in the frequency spectrum. Instruments like guitars, synths, and percussion often occupy the midrange frequencies, where vocals also predominantly reside. This overlap can lead to masking, where the presence of one sound diminishes the clarity of another.

To ensure that vocals cut through the mix, it's essential to manage these interactions carefully. This involves techniques such as EQ, compression, and panning to create space for the vocals and make them stand out without overwhelming the other elements.

Effective use of tools like FUSER can help resolve frequency clashes by intelligently sidechaining and carving out space for the vocals, ensuring they remain clear and prominent.

Additionally, automation can be used to adjust the vocal levels dynamically, keeping them consistent throughout the track and enhancing their interaction with other mix elements.

Preparing Your Vocals for Mixing

Editing and Cleaning Up Vocal Tracks

Before diving into the mix, it's crucial to ensure your vocal tracks are clean and free from unwanted noise. Start by removing any background noise, breaths, and other extraneous sounds that might have been captured during recording.

Tools like noise gates and spectral editors can be incredibly useful for this task. Additionally, use de-essers to tame harsh sibilance that can become prominent once the vocals are processed and amplified in the mix.

Using Tools Like De-Essers and Pitch Correction

De-essers are essential for controlling sibilance, which refers to the harsh 's' sounds that can occur in vocal recordings. By selectively compressing these frequencies, de-essers help maintain the natural tone of the vocals while reducing harshness.

Plugins like RESO can dynamically control problematic frequencies, ensuring a smooth and balanced sound.

Pitch correction tools, such as Melodyne or Antares Auto-Tune, can correct intonation issues, making sure your vocals are in tune without sounding robotic. Subtle pitch correction can enhance the professional quality of your vocals, ensuring they blend seamlessly with the instrumental elements.

Using FUSER to Carve Out Space in the Mix

FUSER is an invaluable tool for resolving frequency clashes between vocals and other elements in your mix. By analyzing the frequency content and sidechaining conflicting elements, FUSER helps create space for the vocals to breathe. This process involves:

• Loading FUSER on the submissive conflicting channels, such as guitars, synths, or pianos. (Group them if needed, or use individual FUSER instances for each channel)
• Sidechaining the vocal to ensure these elements dynamically duck in volume when the vocals are present.
• Fine-tuning the process by adjusting parameters like attack and release to maintain a natural sound.

Employing FUSER in this way ensures that your vocals remain clear and prominent, even in the densest mixes.

By meticulously preparing your vocals and using the right tools, you set a strong foundation for achieving a polished and professional mix. Next, we'll delve into setting the foundation with volume and panning techniques.

Setting the Foundation: Volume and Panning

Initial Volume Setting for Vocals

Setting the initial volume for your vocals is a critical step in the mixing process. Start by bringing your vocal track up in the mix until it is clearly audible but not overpowering.

It’s often helpful to begin by balancing the lead vocal against a single reference instrument, like the kick drum or bass, which helps maintain a consistent baseline level. Ensure that the vocals are neither too buried in the mix nor too forward, disrupting the balance with other elements.

Effective Panning Techniques to Create Space

Panning is an essential technique to create space in your mix and ensure that each element has its own place within the stereo field. Typically, lead vocals are panned centrally to maintain focus and clarity, as this is where listeners naturally expect them to be.

However, background vocals, harmonies, and doubles can be panned left and right to create width and depth.

When panning, consider the overall stereo image:

• Center: Place lead vocals, kick drum, snare, and bass in the center to anchor the mix.
• Left and Right: Spread backing vocals, harmonies, and other supporting elements across the stereo field. This can enhance the perception of space and prevent the mix from sounding cluttered.

Utilizing Automation for Consistent Vocal Levels

Automation is a powerful tool for maintaining consistent vocal levels throughout a track. Relying solely on compression can make vocals sound unnatural and overly processed. Instead, use automation to manually adjust the vocal volume in response to the track's dynamics.

Here’s how to implement effective automation:

• Volume Automation: Smooth out any volume discrepancies by manually raising or lowering the vocal level where necessary. This ensures that softer parts of the performance are audible without making louder sections overpowering.
• Effect Automation: Automate effects like reverb, delay, and EQ to enhance specific parts of the vocal performance, adding interest and dynamics without overwhelming the mix.

Using a gain plugin for automation is one of the most time-intensive production processes, but it's one the best return on time-investment sonically speaking. Keeping the vocals at a consistent level is the first step to making sure they sit well within the context of the entire track.

Making Pro-Level EQ Decisions

Understanding Why It Hard To Make Good Decisions

Millions of producers struggle with trusting their monitors and the response they get in their studio spaces. This is often due to the unique way speakers reproduce audio in untreated rooms, leading to echoes and reflections. These issues can cause frequency boosts and dips, resulting in mixes that sound good in the studio but poor elsewhere.

Setting a Sonic Target

One major mistake producers make is mixing without a specific sonic target. Mixing without a reference can lead to disappointing results because humans are not good at maintaining a frame of reference for sound characteristics. Listeners will compare your music to other professionally produced tracks, so it's essential to have a clear sonic target. This can include elements like:

• Bright vocals
• Wide, slightly darker synths
• Punchy kick with deep sub-bass
• Bass that translates well on small speakers

Finding the Perfect Reference Track

Choose a reference track that closely matches your genre, vibe, and instrumentation. The right reference track should have similar elements to your mix to avoid creating a harsh or unbalanced sound when attempting to match it.

Remember To Start With Balance

Before touching an EQ, set the correct level for each channel. Adjusting levels first can get your sound 80-90% there, reducing the need for extensive EQing. Proper balancing of channels can make elements appear brighter or darker relative to others.

Using REFERENCE for Balance

1. Load REFERENCE Plugin: Use the REFERENCE plugin on your master channel and import your reference track.
2. Loop the Chorus: Compare the chorus of your track with the reference track.
3. Jump Between Mix and Reference: Focus on balancing the vocal in the context of the whole mix. Adjust your mix to match the reference track's balance.

EQing Your Mix for Tonal Balance

1. Remove Unneeded Frequencies: Use a high-pass filter to cut unnecessary low-end energy from vocals and synths to decongest the mix.
2. Compare EQ and Tonal Balance: Use REFERENCE to match the EQ and tonal balance of your mix to the reference track. Adjust each element to ensure your mix sounds comparable to the reference.

Using MIXROOM for Tonal Balance Matching

1. Select A Vocal Preset: Click the presets in the bottom left corner of MIXROOM and monitor your audio to analyse and suggest targets.
2. Analyze and Adjust: Use MIXROOM’s smart bands to make EQ adjustments that align your mix with the reference stem.

Using Compression to Control Dynamics

Importance of Vocal Compression

Compression is the finishing touch when controlling the character and dynamic range of vocals, ensuring that softer parts are audible while louder sections do not overpower the mix. A well-compressed vocal track can maintain a consistent level throughout the song, making it easier to blend with other elements. However, it's important to use compression judiciously to avoid making the vocals sound unnatural or lifeless.

Setting the Right Attack, Release, and Ratio

The attack and release settings on a compressor significantly impact how it responds to the vocal performance. A slower attack allows the initial transients to pass through, preserving the natural impact of the vocals, while a faster attack can help tame overly sharp peaks. The release time should be set so that the compressor returns to a neutral state between phrases, maintaining a smooth and natural sound.

A ratio of around 3:1 or 4:1 is a good starting point for vocals, providing enough compression to control dynamics without overly squashing the signal. Adjust the threshold to ensure that the compressor engages only during the louder parts of the performance.

Parallel Compression for Added Punch

Parallel compression is a technique that blends a heavily compressed version of the vocal with the original, uncompressed signal. This approach allows you to add body and sustain to the vocals without losing the natural dynamics. To achieve this, duplicate the vocal track and apply aggressive compression to the duplicate. Then, blend this compressed track back with the original vocal, adjusting the levels to taste.

Automating Vocal Volume for Consistency

While compression helps control dynamics, it can sometimes sound unnatural if overused. As mentioned earlier, use automation to manually adjust the vocal volume throughout the track. This allows for precise control over the vocal level, ensuring consistency and clarity without relying solely on compression.

By using a gain plugin to automate the vocal volume, you can make fine adjustments that keep the vocal presence consistent, even during dynamic shifts in the song. This technique helps maintain a natural and expressive vocal performance.

Adding Depth with Reverb and Delay

Choosing the Right Type of Reverb

Reverb adds a sense of space and depth to your vocals, making them feel as though they are part of a larger environment. The type of reverb you choose can significantly affect the overall feel of the mix.

Plate reverbs are great for adding a smooth, dense reverb that works well on vocals, while hall reverbs can provide a grand, expansive sound. Room reverbs offer a more intimate and natural space, which can be ideal for genres requiring a more personal vocal presentation.

When selecting a reverb, consider the genre and the emotional context of the song. A lush, long reverb might suit a ballad, while a shorter, tighter reverb might be better for an upbeat pop track. Experiment with different reverb types and lengths to find what complements the vocal and the song best.

Balancing Wet and Dry Signals

Achieving the right balance between the wet (reverb) and dry (original vocal) signals is crucial for maintaining clarity while adding depth. Too much reverb can make vocals sound distant and washed out, while too little can leave them sounding flat and disconnected from the mix. Start with a subtle amount of reverb and gradually increase it until the vocals sit well within the mix without losing their clarity. 

Pro Tip: Check on Monitors, headphones, and laptop speakers in both mono and stereo and find a the best compromised balance for all environments.

Using pre-delay on the reverb can help keep the initial attack of the vocal clear while allowing the reverb to fill in afterwards. This technique can create a sense of depth without muddying the vocal clarity.

Advanced Techniques: Pre-Delay and Ducking

Pre-delay is the time between the original vocal sound and the onset of the reverb. Setting a longer pre-delay can create space for the vocal to remain clear before the reverb tail kicks in, enhancing intelligibility and presence. This is particularly useful for fast-paced vocals where clarity is essential.

Ducking reverb and delay effects can also be beneficial. Ducking involves reducing the reverb or delay level while the vocal is present and bringing it up in the gaps between phrases.

To set this up, ensure your effect is on it's own channel (use a send) then add FUSER to your effect channel and sidechain the original vocal. Play the audio and click resolve conflicts, in FUSER. Now you're affect will duck momentarily, whenever the vocal is heard, ensuring that the vocal remains upfront and clear, with the effects providing depth only when the vocal is not active.

Using Delay to Enhance Vocals

Delay can add depth and rhythmic interest to vocals without the smearing effect of reverb. Short delays can create a doubling effect that thickens the vocal, while longer delays can add echoes that enhance the spatial perception of the track. Syncing the delay to the tempo of the song can create a cohesive and musical effect.

Using stereo delays with different delay times for the left and right channels can widen the stereo image of the vocals, making them sound more expansive and engaging. This technique can be particularly effective in genres like pop and electronic music, where a wide vocal presence is desirable.

By carefully selecting and balancing reverb and delay effects, you can add depth and dimension to your vocals, making them sound rich and engaging within the mix. 

Enhancing Presence with Saturation and Exciters

Using Saturation to Add Warmth and Character

Saturation can be a powerful tool for adding warmth and character to your vocal tracks. It works by introducing subtle harmonic distortion, which can make the vocals sound richer and more full-bodied. Light saturation can help the vocals stand out in the mix without sounding harsh or overly processed.

To apply saturation, start with a plugin that allows for precise control over the amount and type of saturation. Gradually increase the saturation until you notice a slight warmth and enhancement in the vocal tone. Be careful not to overdo it, as too much saturation can lead to unwanted distortion and muddiness.

Employing Exciters for Additional Brightness

Exciters can add brightness and clarity to your vocals by enhancing the higher frequencies. This can help the vocals cut through the mix, especially in dense arrangements. An exciter works by generating high-frequency harmonics, which can bring out the details and nuances in the vocal performance.

When using an exciter, focus on the upper midrange and high frequencies. Start with subtle settings and gradually increase the effect until the desired brightness is achieved. It's important to monitor the overall tonal balance to ensure that the added brightness complements the vocal without making it sound too harsh or sibilant.

Combining Saturation and Exciters for Optimal Results

For the best results, combine the subtle use of saturation and exciters with the tonal shaping capabilities of MIXROOM. This combination can enhance the overall presence and detail of your vocals, ensuring they stand out clearly in the mix. By carefully balancing these effects, you can achieve a warm, bright, and clear vocal sound that complements the rest of your track.

Tackling Common Issues: Sibilance and Plosives

Effective Use of De-Essers

Sibilance refers to the harsh 's' and 'sh' sounds that can become overly prominent in vocal recordings. These frequencies typically reside in the 5-10 kHz range and can be particularly problematic when vocals are processed with EQ and compression. A de-esser is a specialized compressor that targets these frequencies, reducing their intensity without affecting the rest of the vocal performance.

To use a de-esser effectively, start by identifying the problematic sibilant frequencies. Adjust the threshold and frequency settings on the de-esser to target these areas, ensuring that sibilance is controlled without dulling the overall vocal clarity. By carefully fine-tuning these parameters, you can achieve a balanced vocal sound that is free from harsh sibilant peaks.

Techniques to Minimize Plosive Sounds

Plosives are the explosive sounds produced by letters like 'p' and 'b', which can cause distortion and excessive low-frequency energy in vocal recordings. These sounds occur when bursts of air hit the microphone diaphragm directly, creating a popping noise.

To minimize plosives, consider the following techniques:

• Microphone Placement: Position the microphone slightly off-axis from the singer's mouth, or use a pop filter to diffuse the air before it reaches the microphone.
• Editing: Use audio editing software to manually reduce the volume of plosive sounds. This can be done by zooming in on the waveform and applying a volume envelope to the affected areas.
• High-Pass Filter: Applying a high-pass filter can help remove the low-frequency energy caused by plosives. Set the filter to cut frequencies below 80-100 Hz to clean up the vocal without affecting its natural warmth.

Combining De-Essers and Manual Editing

For optimal results, combine the use of de-essers with manual editing techniques. While de-essers are effective for controlling sibilance, manually editing problematic sibilant peaks can provide additional precision. Similarly, while high-pass filters and pop filters can reduce plosive sounds, manual editing allows for fine-tuned control over the vocal performance.

Using RESO for Dynamic Resonance Control

RESO is a powerful tool for managing resonances dynamically, which can help address issues like sibilance and plosives without the need for excessive EQ cuts. By using RESO, you can target and reduce specific resonant frequencies as they occur, maintaining a natural and balanced vocal sound. This approach ensures that the vocal retains its clarity and presence while minimizing harshness and unwanted low-frequency energy.

By effectively managing sibilance and plosives, you can achieve a clean and professional vocal sound that enhances the overall quality of your mix.

 

Final Touches: Balancing Vocals in the Mix

Final EQ and Compression Tweaks

As you near the end of your mixing process, revisit the EQ and compression settings on your vocals to ensure they sit perfectly within the overall mix. As you progressively change the mix, the vocals will need constant attention to ensure they're still sitting well.

Listen critically to how the vocals interact with other elements, making subtle adjustments to enhance clarity and balance.

Small tweaks can make a significant difference, such as slightly boosting the high frequencies to add presence or cutting midrange frequencies to reduce muddiness.

Ensure that the compression settings are fine-tuned to maintain dynamic consistency without squashing the vocal’s natural expression.

Checking the Mix in Different Listening Environments

To ensure your vocals sound great across various playback systems, listen to your mix on different speakers and headphones. This includes studio monitors, consumer headphones, car audio systems, and smartphone speakers.

Each environment will reveal different aspects of the mix, helping you identify any issues that need addressing.

Pay attention to how the vocals sit in the mix in each scenario, making necessary adjustments to ensure they are consistently clear and balanced. Try to listen to reference tracks in these environments too to give your ears an idea of what a good vocal sounds like. 

Using REFERENCE for Comparison

Utilize our REFERENCE plugin to compare your vocal mix against professional tracks. By analyzing how your mix compares to a reference track, you can make informed decisions about final EQ, balance, and compression tweaks. The visual feedback provided by REFERENCE can guide you in achieving a professional-sounding mix that translates well across all listening environments.

Ensuring Cohesion with the Mix

Beyond technical adjustments, ensure that the vocals fit stylistically and emotionally with the rest of the track. This involves blending the vocals seamlessly with the instrumental elements, maintaining a cohesive sound. Adjust reverb and delay levels to match the ambience of the track, and ensure that any added effects enhance the vocal performance without drawing undue attention.

Final Listening Session

Conduct a final listening session with fresh ears to catch any last-minute issues. This is a crucial step to ensure that all elements of the mix, including the vocals, are balanced and polished. Take notes on any areas that stand out, whether they are too loud, too quiet, or need further adjustment. Making these final tweaks ensures that your mix is ready for mastering and eventual release.

By carefully balancing the vocals within the mix and making precise final adjustments, you can achieve a professional and cohesive sound. In the next section, we'll explore real-world examples and case studies to illustrate these techniques in action.

Case Studies

Example 1: Pop Vocal Mixing

In pop music, the vocal is often the focal point, requiring it to be clear, present, and full. Consider the mixing techniques used in a popular track like Ed Sheeran’s "Shape of You".

The vocals are processed with a combination of EQ cuts in the low mids to reduce muddiness and slight boosts in the high mids to add clarity and brightness. Compression is used to ensure consistent levels, and a touch of saturation adds warmth and character.

The use of reverb and delay is subtle, providing depth without overshadowing the vocal presence. This approach ensures the vocal sits prominently in the mix, cutting through the dense arrangement of instruments and electronic elements.

Example 2: Rock Vocal Mixing

In rock music, vocals need to compete with loud and aggressive instrumentals, such as distorted guitars and powerful drums. Take Foo Fighters’ "Everlong" as an example.

The vocals are heavily compressed to maintain consistency against the dynamic backdrop of the track. EQ is used to carve out space for the vocal by reducing frequencies around 300 Hz where the guitars dominate, and boosting around 3-5 kHz to add presence.

Reverb and delay are used more aggressively to create a sense of space and intensity that matches the energy of the music. Automation plays a crucial role in maintaining vocal clarity during both quieter verses and explosive choruses.

Example 3: Hip-Hop Vocal Mixing

In hip-hop, the vocal often drives the track, delivering rhythmic and lyrical content that must be clear and upfront. Kendrick Lamar’s "HUMBLE." is a great example of effective vocal mixing in this genre.

The vocals are processed with precise EQ cuts to remove any unnecessary low-end rumble and enhance clarity in the upper mids. Compression is used to keep the vocal tight and consistent, with parallel compression adding extra punch without losing dynamics.

Reverb and delay are minimal, maintaining a dry and intimate feel that keeps the focus on the lyrical delivery. Saturation is used to add a slight edge, making the vocal sound more aggressive and engaging.
