Audiobook Production Audiobook Production 3 — Questions and Answers
Question 1: What is a 'de-esser' plugin used for in audiobook post-production?
- Removing low-frequency rumble
- Reducing harsh sibilant 'S' and 'SH' sounds (Correct answer)
- Eliminating mouth clicks
- Boosting vocal presence around 3 kHz
Correct answer: Reducing harsh sibilant 'S' and 'SH' sounds
A de-esser is a frequency-specific compressor that targets and reduces overly harsh sibilant sounds like 'S', 'SH', and 'CH' in vocal recordings.
Question 2: Which of the following best describes 'breath editing' in audiobook production?
- Removing all audible breaths from the recording
- Selectively reducing or removing distracting breath sounds while keeping natural ones (Correct answer)
- Adding synthetic breath sounds for realism
- Compressing breath sounds to match dialogue volume
Correct answer: Selectively reducing or removing distracting breath sounds while keeping natural ones
Professional breath editing selectively attenuates only the most distracting inhales while preserving natural breathing to maintain a human, unprocessed feel.
Question 3: What does 'dynamic range compression' do to a vocal recording?
- Increases the difference between loud and soft passages
- Reduces the difference between the loudest and softest parts of a signal (Correct answer)
- Adds harmonic distortion for warmth
- Removes frequencies below 80 Hz
Correct answer: Reduces the difference between the loudest and softest parts of a signal
A compressor reduces the dynamic range by attenuating loud peaks, resulting in a more consistent volume level throughout the narration.
Question 4: A narrator is recording in a home studio with noticeable HVAC noise. What is the most effective solution?
- Apply heavy noise reduction in post-production
- Turn off the HVAC system during recording sessions (Correct answer)
- Record at a higher gain to mask the noise
- Use a high-pass filter set to 500 Hz
Correct answer: Turn off the HVAC system during recording sessions
Eliminating the noise source at its origin — turning off the HVAC during recording — produces far better results than trying to remove noise in post-production.
Question 5: What is 'LUFS' used to measure in audiobook mastering?
- Frequency response of the recording space
- Integrated loudness of an audio program (Correct answer)
- Latency between input and output in a DAW
- Level of ultrasonic frequencies above 20 kHz
Correct answer: Integrated loudness of an audio program
LUFS (Loudness Units relative to Full Scale) measures perceptual loudness, and streaming platforms use it to normalize audio to target levels like -16 LUFS.
Question 6: Which microphone polar pattern is most commonly preferred for solo audiobook narration in a treated studio?
- Omnidirectional
- Figure-8
- Cardioid (Correct answer)
- Hypercardioid
Correct answer: Cardioid
Cardioid microphones pick up sound primarily from the front and reject room noise from the sides and rear, making them ideal for studio narration.
Question 7: What is a 'pop filter' designed to prevent?
- Sibilance from 'S' sounds
- Plosive bursts of air from 'P' and 'B' sounds (Correct answer)
- Microphone feedback from monitors
- High-frequency distortion from overloading the capsule
Correct answer: Plosive bursts of air from 'P' and 'B' sounds
Pop filters diffuse the burst of air from plosive consonants like 'P' and 'B' before it reaches the microphone capsule, preventing low-frequency thumps.
