Audio Editing Audio Editing MCQ 2 — Questions and Answers
Question 1: What does the term 'headroom' refer to in audio editing?
- The physical space above studio monitors
- The difference between the peak signal level and 0 dBFS (Correct answer)
- The amount of reverb applied to a track
- The frequency range reserved for high-end content
Correct answer: The difference between the peak signal level and 0 dBFS
Headroom is the buffer between the highest peak in your audio and 0 dBFS (digital full scale), preventing clipping.
Question 2: Which plugin type is specifically designed to reduce harsh sibilance ('s' and 'sh' sounds) in vocal recordings?
- Flanger
- De-esser (Correct answer)
- Exciter
- Tremolo
Correct answer: De-esser
A de-esser is a frequency-specific compressor that targets and reduces problematic sibilant frequencies, typically between 5–10 kHz.
Question 3: What is the purpose of using a high-pass filter (HPF) on a vocal track?
- To boost presence in the upper midrange
- To remove low-frequency rumble and mud below a set cutoff point (Correct answer)
- To add harmonic distortion for warmth
- To increase the stereo width of the vocal
Correct answer: To remove low-frequency rumble and mud below a set cutoff point
A high-pass filter removes frequencies below the cutoff, cleaning up low-end rumble, mic handling noise, and muddiness from vocal tracks.
Question 4: In a stereo audio file, what does 'mid-side (M/S) processing' allow an editor to do?
- Apply effects only to the left channel
- Independently process the center (mid) and the stereo difference (side) signals (Correct answer)
- Convert stereo to mono for compatibility
- Apply panning automation across a timeline
Correct answer: Independently process the center (mid) and the stereo difference (side) signals
M/S processing encodes a stereo signal into a center mono component (Mid) and a stereo difference component (Side), allowing independent control of each.
Question 5: What does 'clip gain' allow you to do that a channel fader does not?
- Automate volume changes over time
- Adjust the gain of a specific clip before it reaches the channel strip (Correct answer)
- Control the output gain of a plugin chain
- Set the master bus level independently
Correct answer: Adjust the gain of a specific clip before it reaches the channel strip
Clip gain adjusts the level of an individual audio region before it enters the channel's plugin chain, unlike the fader which adjusts post-processing output.
Question 6: Which type of noise reduction works by sampling a section of background noise and then subtracting that noise profile from the entire recording?
- Spectral repair
- Adaptive noise gate
- Broadband noise reduction (Correct answer)
- Dynamic range expansion
Correct answer: Broadband noise reduction
Broadband noise reduction (used in tools like iZotope RX) creates a noise profile from a noise-only sample and subtracts it across the full recording.
Question 7: What happens to audio when it is 'time-stretched' without pitch correction?
- The pitch rises as the tempo increases
- The audio is lengthened or shortened while the pitch changes proportionally (Correct answer)
- The tempo changes but the pitch remains unaltered
- The frequency spectrum is inverted
Correct answer: The audio is lengthened or shortened while the pitch changes proportionally
Basic time-stretching changes the duration of audio, but without pitch correction algorithms, pitch shifts up when sped up and down when slowed.
