Audiobook Production Audiobook Production MCQ 3 — Questions and Answers
Question 1: What is 'punch-and-roll' recording in audiobook production?
- A technique where the narrator physically stops between chapters
- A method where playback rolls into the mistake and the narrator re-records over it seamlessly (Correct answer)
- A mixing technique that boosts the low-mid frequencies
- A way to sync multiple microphones with a clap track
Correct answer: A method where playback rolls into the mistake and the narrator re-records over it seamlessly
Punch-and-roll lets the narrator hear the preceding audio and punch in to re-record only the flawed section, maintaining natural continuity.
Question 2: What is the ACX maximum allowed noise floor for audiobook audio?
- -50 dBFS
- -60 dBFS (Correct answer)
- -70 dBFS
- -80 dBFS
Correct answer: -60 dBFS
ACX requires the noise floor to be -60 dBFS or lower during periods of silence in the finished audio.
Question 3: Which of the following best describes 'room tone' in audiobook production?
- The tonal quality of the narrator's voice
- The ambient sound of the recording environment captured without narration (Correct answer)
- The EQ curve applied to the master bus
- A reference tone used to align playback devices
Correct answer: The ambient sound of the recording environment captured without narration
Room tone is a few seconds of ambient silence recorded in the booth, used to fill gaps or smooth edits during post-production.
Question 4: What effect does a 'de-esser' plugin address in audiobook mastering?
- Removes background hiss from analog tape recordings
- Reduces harsh sibilance on 'S' and 'SH' sounds (Correct answer)
- Corrects pitch drift in the narrator's voice
- Eliminates plosive pops from 'P' and 'B' consonants
Correct answer: Reduces harsh sibilance on 'S' and 'SH' sounds
A de-esser is a frequency-specific compressor that targets and attenuates excessive sibilance in the upper frequency range.
Question 5: In audiobook production, what does 'chapter room tone' refer to?
- A unique EQ preset applied to each chapter
- One second of silence at the beginning and end of each chapter file (Correct answer)
- The ambient noise recorded at the start of each recording session
- A compression setting that varies per chapter
Correct answer: One second of silence at the beginning and end of each chapter file
ACX and other distributors require one second of room tone (silence) at the head and tail of every chapter file.
Question 6: What is meant by 'normalization' in audio post-production?
- Reducing dynamic range by applying heavy compression
- Adjusting the overall gain so the loudest peak reaches a target level (Correct answer)
- Removing all frequencies below 80 Hz from the signal
- Converting the file from stereo to mono
Correct answer: Adjusting the overall gain so the loudest peak reaches a target level
Normalization scales the entire audio file up or down so its loudest peak or integrated loudness hits a specified target value.
Question 7: Which of these issues is most likely caused by a microphone placed too close to a narrator's mouth without a pop filter?
- Excessive room reverb
- Plosive distortion on 'P' and 'B' sounds (Correct answer)
- High-frequency roll-off on consonants
- Phase cancellation between channels
Correct answer: Plosive distortion on 'P' and 'B' sounds
Plosives are bursts of air pressure that hit the mic capsule directly, causing low-frequency thumps or clipping without a pop filter.
