Vocal production Flashcards
What is basic signal flow with vocal production?
The journey your voice takes from the moment you sing into the microphone and when it’s captured by your recording software
How do you record basic signal flow?
Step 1: the microphone
Step 2: connecting to the audio interface
Step 3: adjusting input level on the audio interface (aim for around -10dB to -6dB)
Step 4: the DAW - make a new track and have it connected to your audio interface
Step 5: monitoring your voice - listening to your voice in real time with headphones
What is clean signal path?
Means the audio signal travels without interference through each component of the recording chain
How do you minimise reflections when recording vocals?
1: know your echo enemies - understanding where these reflections come from. Hard surfaces like ceilings and floors can bounce sound around and we want to soften these bounces
2: blankets / pillows - hang up some blankets and utilise soft materials to help catch sound and make sure it doesn’t bounce around too much
3: Magic traps for low end frequencies - stick bass traps in the corners where low end reflections like to hide making your singing sound more clear
4: use sound bouncers (diffusers) - diffusers are like sound bouncers, they scatter reflections without making your room too quiet
5: Place your mic in the right spot - place it away from walls and reflective materials
6: utilise a carpet as they are great for soaking up sound
7: use DIY tricks as sound catchers - minimise the sound of the room as much as possible especially behind the singer, around the microphone as well as above and below you - this will give you that tight, clean, upfront sound
What are two types of microphones?
- condenser
- dynamic
What is a condenser microphone?
- capture a wide range of frequencies and nuances making them ideal for detailed recordings especially for softer sounds like vocals and acoustic instruments
- these microphones are a lot more sensitive so they’re very suitable for studio environments that are controlled with forms of isolation surrounding the singer
What is a dynamic microphone?
- for more robust performance
- they handle higher sound pressure levels making them perfect for louder environments like live performances, micing guitar amps as well as drums
- their robust construction makes them less prone to damage from rough handling or accidental drops
- when there’s less acoustic treatment in the room, a dynamic mic may prove to be a better option for recording
What is a pop filter?
- noise protection filter for microphones
- they reduce popping sounds caused by mechanical impact of fast moving air on the microphone from plosives during recorded speech or singing
Placing your microphone:
Experimenting with the angle and distance to feel your sweet spot where your voice comes through crisply with minimised background noise and reverberation is the art
What is guideline 1 if microphone placement?
- the proximity effect: refers to the change in the tonal characteristics of a microphones response when the sound source gets closer to the microphone
- as a sound source gets closer to the microphone, there is an increase in low end frequency response - this results in a warmer and richer tone in the recorded sound
- it’s crucial to find a balance with distance and experiment with the mic placement
- if you are looking for a more spacial effect with your vocals, try experimenting with a bit more distance
What is guideline 2 of
- experiment with different angles
- tilt the mic slightly up or down until you find the angle that captures the voice just the way you intended
What is the 5 step recording checklist?
1: pick the right mic for the job
2: find the sweet spot for the distance
3: experiment with angles
4: isolate reflections in your room
5: check the gain coming through your audio interface into your DAW making sure you’re hitting the -10dB to -6dB range at the loudest peaks of your singing
What is performance with vocal production?
- the nuance and emotion of your vocals
- there is no amount of post production that can fix a rubbish performance
How do you produce a great performance?
1: set the scene - make yourself comfy and at ease, the more relaxed you are, the better your vocals will flow
2: hydration is key - sip water before and during your vocal session helping your voice stay fresh
3: warm up you voice - warm up as if you are a vocal athlete and give it a gentle wake up call
4: focus on emotional intent to connect the trust and the song to the listener
5: embrace the mistakes
6: experiment with different takes e.g. emotions and tones
7: break it down section by section and then piece it together
8: create an open communication loop - understand what the artist is needing in the moment - you need to facilitate the best performance that you can
What is comping?
- assemble the best parts from multiple takes into a single seamless performance
- a solution to the limitations of one take recordings
- results in a seamless and polished final recording
How do comping work?
- listen and analyse all takes
- select the best parts of each take
- combine into one seamless ‘master’ take
- most refined representation of the artists true potential
What is the workflow for comping?
- make a general composite on an initial listen to all the vocal tracks
- listen again to listen out if you hear any local issues, so any phrases or one word that could be potentially problematic, then you can consider comping
- then you can fade or bring down breaths with gain automation
- remove any mouth clicks - use Rx mouth de-click plugin
- revisit any problem areas again
- when listening to this, listen with auto tune so you can focus on emotion and performance
What is time aligning?
- technique used to synchronise different vocal tracks
- adjusting the timing of individual vocal tracks
- aiming to achieve tight cohesion
How does time aligning work?
- listen and analyse the waveforms to identify timing discrepancies
- carefully adjust the timing of each vocal track in context with the music and lead vocal
- bring all elements into perfect alignment
Why carry out time aligning?
- enhances the overall tightness, groove, and clarity of the vocal
- eliminates phrase issues and ensures that every word hits simultaneously
- the result is a more polished and professional sound
Summary for time aligning:
- the key to achieving precision and synchronisation in vocal performances
- elevates the overall quality of the recording aiding the listeners journey free of distraction
- when something feels late timing wise, it creates a perception of groove
- when something feels a little rushed, often times we perceive this as a mistake
What is an alternate way to align vocals?
An alternate way to align vocals (especially when working with doubles), is a vocal alignment plugin which allows you to side chain your double vocal track with your lead vocal to which is will align on whatever strength you select
What is tuning for vocal production?
- adjustment of a vocalists pitch to achieve a flawless and harmonically accurate performance
- crucial step in modern music production
How does tuning work?
- use tuning software to analyse and adjust the pitch of recorded vocals
- the goal is to create a pitch perfect performance
- navigate the nuances of each vocal track without compromising the expressiveness of the artist
What’s the difference between manual and auto pitch correction?
- the degree of control and precision afforded to the user
What is manual pitch correction?
- manual tuning allows more control and precision
- helps preserve the natural nuance of the vocal
- addresses specific pitch discrepancies
What is auto pitch correction?
- relies on software algorithms to automatically detect and correct pitch errors across the entire performance
- while the approach is more quicker and efficient, it may lack the finesse and tailored adjustments achievable with manual tuning
What approach for tuning is better with manual or auto?
- it depends on the desired outcome
- manual = more control
- auto = more streamlined
- common approach is to use both in tandem
- manually finessing the pitch and tightening up overall pitch with auto tune
Why should you carry out vocal tuning?
- plays a pivotal role in achieving pitch perfect vocals
- elevates the overall production quality
- results in a polished professional sound
What is melodyne?
- the leading manual tuning plugin
What is flex pitch?
The stock version of melodyne
What is ‘input type’ on Antares auto tune pro plugin?
- the type of signal you’re putting in (included pitch such as soprano,alto and tenor)
What is the ‘key’ on Antares auto tune plugin?
The key of your piece for your auto tune to lay in
What is ‘retune speed’ on Antares auto tune plugin?
- how quickly you move to those target pitches that are being told to the auto tune with the key and the scale you are in
What is ‘flex time’ on Antares auto tune plugin?
- allows for expression to come through, so if you have slides up and down or any sort of growls, this tool is going to be much more forgiving for that expression
What is ‘natural vibrato’ on Antares auto tune plugin?
The more you push this up, the more it will accentuate natural vibrato’ and vice versa
What is ‘humanise’ on Antares auto tune plugin?
Adds realism to sustain notes with a higher retune speed so that you don’t create a very robotic effect
What is gain automation?
- do not skip this step
- separated beginners from pros
- gain automation involves adjusting the volume of a vocal track to create a more consistent balanced performance
- aims to address variations in volume that naturally occur during a vocal recording
How does gain automation work?
- producers use automation tools to manually adjust the volume levels of sections within a vocal track
- the goal is to create a consistent volume by mitigating sudden spikes and dips that distract from the overall listening experience
Why carry out gain automation?
- a crucial step in achieving a consistent and balanced vocal performance before compression
- ensures the subsequent compression process operates on a more stable foundation
What is the importance of a gain balanced vocal?
- the compressor may unintentionally emphasize or attenuate certain elements leading to an unnatural and less pleasing results when the gain of the vocals are inconsistent
- gain automation acts as the preliminary sculpture, preparing the vocal track for compression by creating a smooth and controlled dynamic range
- use faders when slicing when making gain changes to prevent any sort of popping
Vocal editing tips:
- edit as many vocals as possible
- take regular breaks to keep your mind fresh for the editing phrase
- give yourself a time limit
- don’t fear being heavy - handed with backing vocals e.g. alot more abrupt edits as it wants be picked up in the context of the mix
- aim for clean takes when comping
- pay close attention to consonant timing - especially in doubles or harmonies with ‘s’ or ‘t’ sounds in relation to the main vocal which will distract the listener
What are doubles and harmonies?
- doubles involve recording the same part twice
- harmonies introduce additional notes that compliment the main melody
- doubles and harmonies provide a fuller, more immersive listening experience
- used in various genres to enhance vocal vocal or instrumentation performances
How do you create doubles?
- recording a second identical take of the vocal, known as a traditional double
- altering certain parameters in the second take, such as using a different microphone, adjusting the pitch slightly, or changing the performance style - this is know as a modified double
What are techniques for capturing doubles?
- 1 single take in unison and layering that with your lead vocal
- recording 2 and sometimes 4 or more doubles, with the intention of spreading those out in the stereo field with panning
What is LCR panning with vocals?
- lead vocals in the center
- doubles and harmonies are panned out hard left and hard right
How do you create harmonies?
- layering harmonies involves careful consideration of each notes role in the chord
- they add emotional depth, create a sense of space, and enhance the overall experience for the listener
What should you consider when using doubles and harmonies?
- make sure to place them where it’s needed
- you will add and cut tracks and doubles and harmonies throughout your piece rather than having them all play continuously crafting a music journey
- it’s much better to be intentional with subbing and harmonies to dial in the emotion of the song
What are gang vocals?
- gang vocals involve recording a group of singers simultaneously
- this technique is used widely across genres to add energy, intensity to a vocal section
- arranging gang vocals involves carefully planning harmonies, dynamics and the number of singers should you choose to work multiple singers
- the goal is to create a cohesive and impactful sound that enhances the overall emotional experience of the music
How do you create gang vocals?
- select a group of singers with diverse vocal tones
- you can do gang vocals yourself by being creative with your own vocal placement to mimic the different qualities that having multiple singers would have
- plan the harmonies ensuring that they compliment the main melody and add depth to the overall sound
- consider layering unison chants with harmonies, and strategically place accents to emphasize key moments in the song
What are techniques for gang vocals?
- recording gang vocals required strategic microphone placement to capture the energy and unity of the group
- capturing the genuine enthusiasm of the group contributes to the power of the gang vocals
Why use gang vocals?
- gang vocals inject a sense of unity and power into a song
- they create a sonic signature that resonates with listeners and enhances the emotional impact of the music
- great for capturing the collective spirit and delivering a memorable musical experience
What are choirs?
- choir-like arrangements involves creating a rich and harmonically complex vocal ensemble
- unlike gang vocals, which emphasize unity and power, choirs aim for a nuanced and intricate blend of voices
- arranging choirs requires meticulous attention to voicing, dynamics and the overall harmonic structure
What is counterpoint?
- counterpoint in music involves the combination of different, independent melodies that are played or sung simultaneously
What are techniques for producing choirs?
- demands a thoughtful approach to capture the subtleties of each voice
- encourage singers to deliver nuanced performances, allowing for dynamic expression
- the goal is to capture the delicate interplay of voices within the choir
Why use choirs?
- choir - like arrangements bring a level of sophistication and emotional depth to music
- convey a sense of grandeur, nostalgia or spirituality depending on the context
What is the difference between choirs and gang vocals?
- choirs emphasize intricate harmonies and nuanced voicings, creating a refined and classical aesthetic
- gang vocals focus on unity and power, often used in contemporary genres for anthemic choruses or energetic moments
What are ad-libs?
- Spontaneous and improvisational vocal embellishments
- they add flair, emotion and a distinctive touch to a song
What are techniques for creating ad libs?
- Experiment with layering ad libs, adjusting their volume and panning to create a dynamic and immersive experience
- encourage improvisation into a recording session, provide the artist with the freedom to experiment allowing for genuine and unrestrained expressions
Why carry out ad-libs?
- ad libs serve as a vehicle for artists to inject their personality and spontaneity into a song
What is pitch / formant shifting?
- pitch shifting changes the note
- formant shifting changes the colour or tonality, offering creative possibilities
- exploring advanced pitch shifting techniques involves manipulating tiny vocal fragments independently
- this method allows for subtle or extreme pitch alterations creating ethereal effects commonly found in electronic or experimental music
- formant shifting is a technique that can drastically alter vocal character without changing the pitch
- pitch and formant shifting are essential for pushing creative boundaries
- they are gateways to sonic exploration
- the formant essentially emulates the throat length of the vocalist
- the logic stock plugin for this is ‘vocal transformer’s
What is a vocoder?
- short for ‘voice encoder’
- vocoders combine the characteristics of a modulator (typically with a human voice) and a carrier (usually a synthesizer), creating a distinctive sound that merges both elements
- adds a robotic, or synthesized quality to vocals
What are vocoder techniques?
- consider vocoders in dynamic ways, such as creating harmonies, enhancing background vocals, or adding a futuristic touch to lead vocals
- automating vocoder parameters over time can introduce evolving textures and contribute to the overall sonic narrative
Why use vocoders?
- vocoders hold a unique place in vocal production because they offer a bridge between the organic and synthetic
- they push the boundaries of vocal creativity
What is modulation?
Effects of audio manipulation
What are the different types of modulation?
- flanger
- phaser
- chorus
What is a flanger?
- slight delay creates a sweeping jet-like sound
What is a phaser?
- produces a swirling, spacey effect and when applied to vocals, it provides a sense of movement / intrigue
- the first stage is splitting the signal so the incoming audio signal is divided into two parts or more
- the next part is phase shifting where the signal is sent through a series of filters called all pass filters which change the phase of certain frequencies within the signal, mixing the original signal, and the phase shifted signals are mixed back together
- this process creates peaks and troughs in the frequency spectrum which move up and down in frequency - these peaks and troughs give the characteristic of a swirling sound associated with a phaser
What is chorus?
- introduces a rich, lush quality to vocals
- it’s like creating a vocal ensemble, making the voice sound larger than life
- works by duplicating the original audio signal and then slightly delaying each duplicate and then modulating the pitch of each duplicate slightly
Why use modulation?
- they introduce motion, depth and character to vocal performances
- each type evokes a distinct emotion
What emotions can you relate to modulation?
- incorporating modulation begins by choosing the right effect for the desired emotional impact
- a flanger: might evoke a sense of anticipation or excitement
- a phaser: can create a dreamy and surreal atmosphere
- a chorus: introduces warmth and comfort
