1
Q
What is basic signal flow with vocal production?
A
The journey your voice takes from the moment you sing into the microphone and when it’s captured by your recording software
2
Q
How do you record basic signal flow?
A
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
3
Q
What is clean signal path?
A
Means the audio signal travels without interference through each component of the recording chain
4
Q
How do you minimise reflections when recording vocals?
A
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
5
Q
What are two types of microphones?
A
- condenser
- dynamic
6
Q
What is a condenser microphone?
A
- 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
7
Q
What is a dynamic microphone?
A
- 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
8
Q
What is a pop filter?
A
- 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
9
Q
Placing your microphone:
A
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
10
Q
What is guideline 1 if microphone placement?
A
- 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
11
Q
What is guideline 2 of
A
- 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
12
Q
What is the 5 step recording checklist?
A
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
13
Q
What is performance with vocal production?
A
- the nuance and emotion of your vocals
- there is no amount of post production that can fix a rubbish performance
14
Q
How do you produce a great performance?
A
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

68
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
69
What is chorus?
- introduces a rich, lush quality to vocals
- it's like creating a vocal ensemble, making the voice sound larger than life

98
What is compression?
- a technique used to reduce the dynamic range of an audio signal
- compression evens out the volume levels of an audio signal by reducing the difference between the loudest and quietest part
99
How does compression relate to vocal production?
- leveling the dynamics of the wide dynamic range of vocals
- improve intelligibility: compression can bring quieter vocal details such as whispers or softer vocal phrases up in volume which improves the clarity in these areas without raising the overall volume
- controlling peaks: to tame vocals that often have harsh peaks within their vocals
- enhancing presence: by reducing the dynamic range of the vocal, compression can make the vocal sound more upfront and present in the mix
- increasing perceived loudness: compression can make vocals sound more louder and more prominent in the mix without actually increasing their peak volume - by reducing the dynamic range, producers can increase the volume of the vocal levels closer to the maximum without causing distortion of discomfort
100
What are common types of compression used on vocals?
- Optical compression
- VCA compression
- FET compression
- Tube compression
101
What is optical compression?

114
What is multi and compression?
A technique that divides the audio signal into multiple frequency bands and applies compression independently to each band
115
How does multiband compression work?
- splitting the signal: the audio signal is split into multiple frequency bands using crossover filters - each frequency band covers a specific range of frequencies such as bass, mid range and treble
- compression: a compressor is applied to each frequency band independently, this means that compression settings such as threshold, ratio, attack and release can be adjusted separately for each band
- processing: compression is applied to each frequency band based on the level of the signal within the band - this allows for targeted compression of specific frequency ranges such as controlling low end rumble, taming mid range hard frequencies or smoothing out sibilance in the high end
- recombining the signal: after compression is applied to each frequency band, the processed bands are recombined to create the final compressed audio signal
116
Why use multiband compression?
- greater control
- reduced pumping and artifacts
- versatility
117
How does multiband compression relate to vocals?
- De-essing: multiband compression can be used specifically to target and control sibilance in vocal recordings by compressing only the high frequency bands
- taming resonances: multiband compression allows engineers to isolate and compress specific frequency bands where resonances occur
- balancing tone: multiband compression enables producers to independently adjust the dynamics of different frequency ranges within the vocal signal which can be useful for balancing the tonal characteristics of the vocal e.g. boosting presence in the mid range
- controlling dynamics: multiband compression offers precise control over the dynamics of vocals across different frequency ranges
- enhancing clarity: by selectively compressing specific frequency bands, multiband compression can help enhance the clarity and intelligibility of vocals
118
What is a De-esser?
- used to remove excessive sibilance from vocal recordings
- works by detecting the frequencies associated with sibilant sounds and then applying dynamic equalisation or compression to reduce their intensity - mostly between 4-10KHz
119
What are the parameters of a De-esser?
- frequency range: specifies the range of frequencies the De-esser will target for processing
- threshold: determines the level at which the De-esser begins to attenuate or compress sibilant frequencies
- detection mode: includes peak detection, RMS detection and spectral analysis. Peak detection responds to the transient peaks in the signal, while RMS detection analyses the overall level of the signal over time. Spectral analysis examines the frequency content of the signal to identify sibilant frequencies more accurately
- processing type: includes dynamic equalisation, compression and frequency dependant gain reduction
- attack and release times: controls the speed at which the De-esser responds to changes in the input signal
- ratio: determines the amount of gain reduction applied to sibilant frequencies above the threshold level
120
What is saturation?
An audio processing effect that introduces harmonic distortion to audio signals, mimicking the characteristics of analog tape, tubes or other analog hardware
121
How does saturation work?
- soft clipping: where the peaks of the audio are gently rounded off rather than abruptly clipped - when the signal exceeds a certain level, the waveform is smoothly compressed resulting in a more rounded shape - this soft clip creates harmonies which are additional frequencies that are multiples of the original signals frequencies
- harmonic generation: As the audio signal passes through a saturator, non lineararities in the processing circuitry cause the generation of harmonics and these add complexity to the sound by introducing frequencies that were not present in the original signal
- dynamic response: different saturators have varying dynamic responses meaning they may react differently to changes in the input level - some saturators respond dynamically to the input signal adjusting the amount of distortion based on it's amplitude - this dynamic response can add further musicality and complexity to the saturation effect
- frequency dependence: some saturators are suppose to emphasize certain frequency ranges more than others - for example, tape saturation plug-ins often accentuate low frequencies white tube saturation may emphasize mid-range frequencies - this frequency dependence can contribute to the characteristic tone and colouration of the saturation effect
- mix control: allows users to blend the saturated signal with the dry unprocessed signal
122
How does saturation relate to vocal production?
- warmth and depth: introduces harmonics and subtle distortion - can help to enrich the sound of vocals making them sound more full - bodied and organic particularly in genres such as soul, jazz and folk
- tonal enhancement: saturation can add richness and colouration to the sound - by emphasizing certain harmonics, and frequencies, saturation can help vocals cut through the mix and stand out while maintaining a natural and pleasing tonal balance
- character and texture: saturation can impart a distinctive character and texture to vocals giving them a sense of character and personality
- glue and cohesion: saturation can act as a sonic glue blending individual vocal tracks with the rest of the mix and creating a cohesive sound by adding subtle compression and harmonics, saturation can help vocals form a more unified sound
- emulation of vintage equipment: saturation plug-ins often include emulations of vintage analog equipment such as tape machines, tube preamps or analog consoles - these emulations can provide authentic, vintage sounds or textures allowing producers to create the sonic characteristics of classic recordings and add a nostalgic vibe to modern vocal productions
123
What is limiting?
Works by reducing the gain of the signal when it reaches or exceeds the threshold, effectively limiting it's peak altitude
124
How does limiting work?
- threshold: a threshold level is set above which the limiting action takes affect, any audio signal that exceeds the threshold will be subjected to gain reduction
- gain reduction: when the amplitude of the audio signal crosses the threshold, the limiter automatically reduces the signals gain to prevent it from exceeding the threshold level
- attack time: determines how quickly it responds to signals that exceed the threshold - a fast attack allows the limiter to react quickly to sudden peaks
- release time: determines how quickly it returns to the normal gain after the signal falls below the threshold
- ceiling level: specifies the maximum amplitude to which the signal is limited, any audio signal that would exceed this level are effectively limited to the ceiling, preventing clipping and distortion
125
How does limiting relate to vocal production?
- dynamic control
- prevention of clipping
- increased loudness
- consistency in performance
126
What is parallel processing?
A technique used to blend a heavily processed signal with the original dry signal
127
How does parallel processing work?
- duplicate the signal: original audio signal is duplicated creating two identical copies of the audio track
- apply processing: heavy compression, EQ or distortion are applied to one of the duplicated signals - the processing is usually more extreme than what you would apply directly to the original sound
- blend the signals: the processed signal is then blended back with the original dry signal using a fader or mixer - the blend control allows the audio engineer to adjust the balance between the processed and dry signals determining the amount of processing applied to the overall sound
128
What are common parallel processing uses?
- compression: parallel compression is a popular technique used to add weight, pressure and impact to individual tracks or the overall mix by blending a heavily compressed signal with the original dry signal - you can have great control over the dynamics of the mix whilst preserving the natural sound
- equalisation: by blending the EQ signal with the dry signal, engineers can achieve tonal balance and enhancement without compromising the integrity of the original sound
- saturation and distortion: can help to add warmth, depth and character to individual tracks or the overall mix enhancing the sonic texture and vibe of the music
129
What is reverb?
- a natural phenomenon that occurs when sound waves reflect off surfaces in an environment creating a complex.pattern of multiple rapidly decaying echoes
- in audio production, reverb refers to the artificial replication or simulation of this phenomenon
- it's used to add depth, dimension and a sense of space to audio recordings
130
How does reverb work?
- reflections: in a real acoustic space, sound waves emitted from a source bounce off surfaces - these reflections blend together creating a sense network of echoes that give the perception os space and ambience
- early reflections: the initial reflections of sound waves arrive at the listeners ears within a very short time after the direct sound - these early reflections give special cues about the size and shape of the environment
- reverberation: as sound waves continue to reflect off surfaces, they gradually lose energy due to absorbtion and diffusion, resulting in a decay of reverbation over time
131

144
Why use delays?
- creates spacial enhancement
- rhythmic effects
- doubling and thickening
- emotional impact
145
How does delay work?
- captures an audio signal, storing it temporarily in a buffer, and then playing it back at a specified period of time
- input signal: the process begins with an input signal
- buffering; the input signal is sent to a buffer which is a temporary storage space in the audio processing system - the buffer holds the audio signal for a certain amount of time
- delay time: determines how long the audio signal is stored in the buffer before being played back
- play back: after the delay time elapses, the buffer signal is played back through the audio signal - this creates a series of delayed copies of the original input signals
- feedback: in some delay effects a portion of the delayed signal is fed back into the buffer, creating multiple repetitions of feedback loops - this can lead to the signal decaying over time or sustaining indefinitely
- mixing: the original input signal and the delay signal are mixed together to achieve a desired balance
- output: the combined signal is sent to the output of the audio processing system
146
How does delay relate to vocal production?
- depth and dimension

What are inserts?
- direct processing: inserts apply the reverb or delay effect directly to the vocal track itself - this means the effect is applied solely to the vocal signal on the track where the insert is placed
- control: inserts provide precise control over the level and the parameters of the effect for each individual vocal track - this allows for tailored adjustments to fit the specific need of each vocal performance
- resource intensive: having a reverb/delay on every single insert on all of your tracks may cause issues with your DAW especially if you're working with a large project
168
What are sends?
- parallel processing: this sends a portion of the vocal signal to a separate auxillary track often referred to as a return track where the reverb or delay effect is applied - this allows for parallel processing where the dry signal remains unaffected and the wet signal with the effect is blended in
- flexibility: sends offer greater flexibility and efficiency, especially when using the same reverb or delay effect across multiple vocal recordings
- consistency: sends ensure consistency in the reverb or delay effect across multiple vocal tracks as they all share the same return track - this helps maintain coherence and balance in the mix
- resource management: much more efficient for CPU by not using so many plug-ins on inserts
169
Considerations for mixing vocals with spacial effects:
- blend and balance: experiment with the blend of the dry, unaffected vocals and wet effected vocals to achieve the desired balance - adjust the send level to control the amount of reverb or delay effect applied to the vocals
- pre-delay and decay time: pay attention to these with a reverb effect to ensure they compliment the vocal performance without masking the clarity of the vocals
- EQ and filtering: use these to shape the frequency response of the effect - this can help to prevent build up of the low frequencies and tame any harsh or muddy frequencies that may interfere with the vocals
- automation: use automation to dynamically adjust the send levels of reverb and delay throughout the song
170
What is a vocal chain?
- refers to a series of audio processing effects and plug-ins applied to a vocal track to enhance it's sound
- the purpose of a vocal chain is to sculpt the vocal sound, correct any imperfections, and achieve the desired tone and clarity
171
What goes on a vocal chain?
- preamp/input gain: the vocal signal is first routed through an input or preamp stage to boost its level, and bring it to an optimal recording level
- equalisation: altering the tone and sonic energy within an audio signal with boosts and cuts on the frequency spectrum
- compression: applied to control the dynamic range of the vocal signal, reducing the level of loud peaks while simultaneously boosting the quiet passages
- De-essing: employed to detect any problematic or sibilant frequencies improving overall clarity and smoothness
- saturation and harmonic enhancement: can help to emulate the pleasing qualities of analog recording equipment
- effects (reverb/delay): can be applied to add spatial dimension, depth and ambience
- final processing and mixing: the final vocal is balanced and integrated into the mix with further potential processing with EQ, automation and general level balancing
172
