CMP Audio Recording and Editing 2 — Questions and Answers
Question 1: What is the primary purpose of a pop filter when recording vocals?
- To boost high frequencies
- To reduce plosive sounds caused by bursts of air (Correct answer)
- To add reverb to the signal
- To increase microphone sensitivity
Correct answer: To reduce plosive sounds caused by bursts of air
A pop filter diffuses bursts of air from plosive consonants (p, b) before they hit the microphone diaphragm, preventing distortion.
Question 2: What does 'comping' mean in audio recording?
- Applying compression to a track
- Selecting the best sections from multiple takes to create one ideal performance (Correct answer)
- Adding a compander to the signal chain
- Compensating for latency in a DAW
Correct answer: Selecting the best sections from multiple takes to create one ideal performance
Comping involves choosing the strongest phrases or notes from multiple recorded takes to assemble a single, polished composite performance.
Question 3: Which microphone polar pattern captures sound equally from all directions?
- Cardioid
- Figure-8
- Supercardioid
- Omnidirectional (Correct answer)
Correct answer: Omnidirectional
An omnidirectional pattern has equal sensitivity at all angles, capturing room sound and sources from every direction.
Question 4: In a DAW, what is the function of a 'crossfade' at an edit point?
- To fade the entire track to silence
- To smoothly blend two adjacent audio regions and eliminate clicks (Correct answer)
- To transpose the pitch of the edit region
- To apply sidechain compression at the edit boundary
Correct answer: To smoothly blend two adjacent audio regions and eliminate clicks
A crossfade overlaps the end of one region with the start of the next, creating a smooth transition and eliminating any click or pop at the edit point.
Question 5: What is 'gain staging' in a recording session?
- Increasing plugin gain to maximum before mixdown
- Setting appropriate signal levels at each stage of the signal chain to optimize headroom and noise (Correct answer)
- Recording each instrument at a different stage of the session
- Applying multiple gain plugins in series
Correct answer: Setting appropriate signal levels at each stage of the signal chain to optimize headroom and noise
Gain staging means setting each device in the signal chain (preamp, interface, DAW) to a healthy level — loud enough above the noise floor but with sufficient headroom to prevent clipping.
Question 6: When recording a drummer, which mic placement technique uses a single coincident pair above the kit to capture a natural stereo image?
- XY coincident stereo (Correct answer)
- ORTF spacing
- Binaural recording
- Mid-Side (MS)
Correct answer: XY coincident stereo
XY coincident stereo places two matched cardioid mics at 90° to each other at the same point, creating a phase-coherent stereo image of the drum kit.
Question 7: What is the noise floor in an audio recording context?
- The loudest signal a system can record before distortion
- The lowest level of background noise inherent in a recording system (Correct answer)
- The frequency at which a microphone rolls off bass
- The amount of latency added by a plugin
Correct answer: The lowest level of background noise inherent in a recording system
The noise floor is the residual self-noise of the recording system — the minimum sound level below which signals cannot be distinguished from system noise.
