Module 7: Vocal Production and Recording

Techniques for recording and processing vocals

Recording and processing vocals require careful attention to capture a clean and polished performance. Here are some techniques for recording and processing vocals:

Recording Techniques:

Microphone Selection: Choose a microphone that suits the vocalist and the desired sound. Dynamic microphones are generally more robust and handle high sound pressure levels well, while condenser microphones capture more detail and nuances.
Microphone Placement: Position the microphone to capture the best sound from the vocalist. Start with the microphone placed about 6-8 inches away from the vocalist's mouth and experiment with slight adjustments to find the sweet spot. Avoid plosive sounds by using a pop filter.
Room Acoustics: Consider the room acoustics when recording vocals. A well-treated and acoustically controlled space minimizes unwanted reflections and helps capture a cleaner and more focused vocal sound.
Headphone Mix: Provide the vocalist with a comfortable headphone mix that includes the instrumental backing track and possibly a reference mix. Ensure they can hear themselves clearly without strain.
Performance: Encourage the vocalist to deliver their best performance. Create a relaxed and supportive environment to help them feel comfortable and confident.

Processing Techniques:

Editing: Start by editing the vocal takes to remove any mistakes, breaths, or unwanted noise. Use a digital audio workstation (DAW) to trim, cut, and arrange the vocal clips as needed.
Pitch Correction: If necessary, use pitch correction tools sparingly to correct minor pitch inaccuracies. Ensure that the correction maintains a natural and musical sound.
Equalization (EQ): Apply EQ to shape the frequency response of the vocals. Boost or cut specific frequencies to enhance clarity, reduce muddiness, or address any tonal issues. Pay attention to the presence and intelligibility of the vocals in the mix.
Compression: Use compression to control the dynamic range of the vocals and create a more consistent level. Apply gentle compression to even out the performance and add sustain if desired. Be mindful not to over-compress and squash the natural dynamics.
De-Essing: Reduce sibilance (harsh "S" or "T" sounds) with a de-esser. De-essers target specific frequency ranges where sibilance occurs and reduce the level without affecting the overall vocal performance.
Doubles and Harmonies: Record additional vocal tracks for doubling or harmonizing with the main vocal. Process these additional tracks similarly to the lead vocal to ensure a cohesive and blended sound.
Spatial Effects: Add subtle reverb or delay to create a sense of space and depth in the vocals. Use caution not to overdo it, as excessive effects can detract from the clarity and focus of the vocals.
Automation: Utilize automation to adjust volume levels, EQ, and effects parameters throughout the vocal performance. Automate to emphasize specific phrases, create dynamic changes, or address any mix imbalances.
Creative Processing: Explore creative processing techniques to add character or unique effects to the vocals. This can include subtle saturation, modulation effects, or experimental processing, depending on the artistic vision of the song.

Remember, the specific techniques and processing choices will depend on the genre, style, and desired aesthetic of the vocals. Trust your ears and make adjustments accordingly to achieve a clean, balanced, and emotive vocal sound in your mix.

Working with vocal harmonies and doubles

Working with vocal harmonies and doubles can greatly enhance the impact and depth of your vocal recordings. Here's an explanation of these techniques:

Vocal Harmonies: Vocal harmonies are additional vocal parts that complement the main vocal melody. They add richness, depth, and complexity to the overall vocal sound. Here's how you can work with vocal harmonies:

Melodic and Interval Selection: Determine the melodic lines and intervals that harmonize with the main vocal melody. Consider using basic harmonies such as thirds, fifths, or octaves, or explore more complex harmonies depending on the musical style and arrangement.
Recording Multiple Tracks: Record each vocal harmony part separately, ensuring precise pitch and timing. It's often helpful to provide a reference track of the main vocal melody for the vocalist to follow.
Layering and Balance: Layer the recorded vocal harmony tracks, adjusting the volume levels and panning positions to create a balanced blend. Experiment with different panning positions to create a wide stereo image or to place specific harmonies in certain positions within the mix.
EQ and Processing: Apply EQ and other processing techniques to the vocal harmonies. Use similar processing as the main vocal to maintain consistency, but also consider slight variations to make the harmonies sit well within the mix. Avoid excessive processing that may detract from the natural and blended sound of the harmonies.
Arrangement and Expression: Pay attention to the arrangement and expression of the vocal harmonies. Ensure that they complement the main vocal and other instruments in the mix. Experiment with different harmonization techniques, such as parallel movement, counterpoint, or call-and-response patterns, to add interest and musicality.

Vocal Doubles: Vocal doubles involve recording an additional take of the main vocal melody to create a thicker and fuller vocal sound. Doubles can add depth, texture, and a sense of presence to the vocals. Here's how you can work with vocal doubles:

Recording Multiple Takes: Record the main vocal melody multiple times to capture different performances of the same part. Aim for consistency in pitch and timing, while allowing for subtle variations in delivery and expression.
Layering and Alignment: Layer the recorded vocal double tracks, aligning them with the main vocal for precise timing and phrasing. Use editing techniques like crossfades or time-stretching to ensure a seamless blend between the double tracks.
Panning and Processing: Experiment with panning positions to create a wider stereo image. Pan the main vocal and its double towards the center for a focused sound, while slightly widening the panned positions of the additional doubles. Apply similar processing techniques used on the main vocal to maintain cohesiveness.
Blend and Balance: Adjust the volume levels of the main vocal and its doubles to create a balanced and blended sound. Be mindful not to overpower the main vocal with the doubles, but rather to enhance the overall vocal presence and impact.
Automation and Expression: Use automation to fine-tune the blend and expression of the vocal doubles. Make subtle volume adjustments or apply selective EQ automation to maintain a smooth and balanced mix.

Vocal harmonies and doubles can elevate the emotional impact and musicality of your vocal recordings. Experiment with different harmonization techniques, layering approaches, and processing choices to achieve a compelling and well-integrated vocal arrangement. Trust your ears and make adjustments that best serve the song and its desired artistic vision.

Editing and comping vocal takes

Editing and comping vocal takes are important steps in the vocal production process that involve selecting the best parts from multiple takes and creating a cohesive and polished vocal performance. Here's an explanation of these techniques:

1. Editing Vocal Takes:

Trimming and Arranging: Start by listening to all the recorded vocal takes. Trim the beginning and end of each take to remove any unwanted noise or extraneous sounds. Then, arrange the takes in your digital audio workstation (DAW) to have them easily accessible for comping and editing.
Pitch Correction: If there are any noticeable pitch issues in specific sections of a take, use pitch correction tools sparingly to correct minor inaccuracies. Be careful to maintain the natural and musical quality of the vocal performance.
Breath and Noise Removal: Edit out any excessive breaths, clicks, pops, or other unwanted noises that may distract from the vocal performance. Use crossfades or fades to ensure smooth transitions between edited sections.
Time Alignment: Align vocal phrases and sections that may have slight timing discrepancies. This helps to create a tighter and more cohesive vocal performance. Use time-stretching or nudging techniques to align the waveforms precisely.

2. Comping Vocal Takes:

Take Selection: Listen to each recorded vocal take and identify the sections or phrases with the best overall performance. Focus on aspects such as pitch accuracy, tone, emotion, and delivery. Select the best parts from each take to build a composite or "comped" vocal track.
Creating a Composite Track: In your DAW, create a new track or playlist where you will compile the selected sections from the different takes. Copy and paste the chosen sections from each take into the composite track, ensuring smooth transitions and crossfades between the segments.
Crossfading and Blend: Use crossfades or fade-in/fade-out techniques to create seamless transitions between the edited sections. Pay attention to the timing and overlap of the crossfades to avoid any audible artifacts. Adjust the volume levels of the comped sections to ensure a balanced and cohesive vocal performance.
Refinement and Fine-Tuning: Once the comped vocal track is created, listen to it in the context of the mix. Make any necessary additional edits, such as removing redundant breaths, adjusting timing, or addressing any remaining pitch inconsistencies.
Post-Comping Processing: Apply any additional processing required for the comped vocal track, such as equalization (EQ), compression, or effects. Ensure that the processing remains consistent across the comped sections, maintaining a cohesive and natural sound.

The goal of editing and comping vocal takes is to create a polished and coherent vocal performance. Take your time to listen critically, make thoughtful selections, and craft a comped vocal track that showcases the best moments from the recording sessions. Remember to maintain the integrity of the original performance and always prioritize the emotional impact and musicality of the vocals.

Mixing vocals in the context of a song

Mixing vocals in the context of a song involves balancing the vocals with the instrumental elements, creating a clear and impactful vocal presence, and ensuring that the vocals sit well within the overall mix. Here's an explanation of the key aspects of mixing vocals:

1. Balancing Levels: Start by setting the level of the vocals in relation to the other instruments in the mix. Adjust the vocal fader to achieve a balanced blend where the vocals are audible and clear without overpowering or getting lost in the mix. Pay attention to the dynamic changes within the vocal performance and ensure they remain consistent in relation to the rest of the song.

2. EQ and Tonal Balance: Use EQ to shape the frequency response of the vocals and achieve a balanced tonal mix. Here are some considerations:

Cutting Unwanted Frequencies: Use EQ cuts to remove any unnecessary low-end rumble or high-frequency harshness that might be present in the vocal recordings.
Boosting Presence: Add gentle boosts in the upper midrange (around 2-5 kHz) to enhance the presence and clarity of the vocals, making them cut through the mix without sounding harsh.
Addressing Muddiness: Make subtle cuts in the lower midrange (around 200-500 Hz) to reduce any muddiness or boxiness that could affect the intelligibility and overall vocal clarity.

3. Compression and Dynamics: Apply compression to control the dynamic range of the vocals and achieve a consistent and polished sound. Here's how compression can be used on vocals:

Evening out the Performance: Use gentle compression to even out the levels of the vocal performance. This helps to tame loud peaks and brings up softer phrases, resulting in a more balanced and controlled vocal sound.
Adding Sustain: Apply a moderate attack and release time to allow the compressor to shape the sustain of the vocals, adding smoothness and presence to the overall performance.
De-essing: Use a dedicated de-esser or a dynamic EQ to reduce sibilance and taming harsh "s" or "t" sounds that can be distracting. Set the de-esser to target the specific frequency range of sibilance and control it transparently.

4. Stereo Placement and Effects: Consider the stereo placement of the vocals and the use of effects to enhance their presence and space within the mix. Here are some techniques:

Centered Vocals: Keep the main lead vocals centered in the stereo field to maintain focus and clarity. This helps ensure that the vocals remain the primary focus of the mix.
Stereo Widening: Add subtle stereo widening effects or use stereo enhancement plugins on vocal doubles or harmonies to create a wider stereo image. Be cautious not to overdo it, as excessive widening can compromise the center focus and coherence of the vocals.
Reverb and Delay: Apply reverb and delay to create a sense of depth and space for the vocals. Use them subtly to place the vocals in a natural or desired sonic environment. Consider using different reverb or delay settings for different vocal elements, such as lead vocals, harmonies, or ad-libs.

5. Automation and Expressiveness: Utilize automation to fine-tune the vocal performance throughout the song. Make adjustments to the volume levels, panning, and effects parameters to emphasize certain phrases, enhance dynamics, or create special moments within the vocals.

Remember, the goal of mixing vocals is to ensure that they serve the song and convey the intended emotion and message. Continuously reference the vocals within the context of the entire mix, make critical listening evaluations, and trust your ears to achieve a balanced, clear, and impactful vocal presence in your final mix.
