Audio Editing Audio Editing MCQ 4 — Questions and Answers
Question 1: What is the role of 'bus compression' applied to a drum bus in mixing?
- To add artificial reverb to individual drum hits
- To glue the individual drum tracks together and add punch and cohesion (Correct answer)
- To remove resonant frequencies from toms and snare
- To convert the stereo drum mix to mono
Correct answer: To glue the individual drum tracks together and add punch and cohesion
Bus compression on a drum group subtly reduces the dynamic range of all drum elements together, making them feel more cohesive and energetic as a unified kit.
Question 2: What is 'parallel compression' (also called New York compression)?
- Applying identical compressor settings to two separate tracks
- Blending a heavily compressed version of a signal with the original uncompressed signal (Correct answer)
- Using two compressors in series on a single channel
- Compressing only the mid channel in an M/S processing setup
Correct answer: Blending a heavily compressed version of a signal with the original uncompressed signal
Parallel compression mixes a heavily squashed signal with the dry original, preserving natural transients and dynamics while adding density and sustain.
Question 3: Which sample rate is most commonly used for professional audio production intended for streaming or CD distribution?
- 22,050 Hz
- 44,100 Hz (Correct answer)
- 96,000 Hz
- 192,000 Hz
Correct answer: 44,100 Hz
44,100 Hz (44.1 kHz) is the standard sample rate for CD audio and most streaming platforms, providing full reproduction of frequencies up to ~22 kHz per the Nyquist theorem.
Question 4: What editing technique involves selecting the best phrases or sections from multiple recorded takes to assemble a single ideal performance?
- Quantizing
- Comping (Correct answer)
- Normalizing
- Bouncing
Correct answer: Comping
Comping (composite editing) involves reviewing multiple takes of the same part and selecting the best moments from each to build one final, polished performance.
Question 5: In audio editing software, what does 'non-destructive editing' mean?
- Editing that only affects frequencies below 200 Hz
- Edits are applied without permanently altering the original audio file on disk (Correct answer)
- A mode that prevents any plugins from processing the audio signal
- Editing that removes silence without changing the waveform shape
Correct answer: Edits are applied without permanently altering the original audio file on disk
Non-destructive editing stores edit decisions as instructions in the project file, leaving the original audio file untouched and allowing unlimited undo.
Question 6: What does 'inter-sample peak' (ISP) refer to in mastering?
- A peak that occurs between two adjacent audio tracks in a playlist
- A transient peak that occurs between digitally sampled points and can cause clipping during D/A conversion (Correct answer)
- The maximum allowable peak level set by a streaming platform
- A peak that is shared identically across both channels of a stereo file
Correct answer: A transient peak that occurs between digitally sampled points and can cause clipping during D/A conversion
Inter-sample peaks occur at points between digital samples; they can exceed 0 dBFS when reconstructed by a DAC and cause distortion even if the digital file shows no clipping.
Question 7: Which type of reverb plugin algorithm simulates the acoustic characteristics of a real physical space by using recorded impulse responses?
- Algorithmic reverb
- Spring reverb
- Convolution reverb (Correct answer)
- Plate reverb
Correct answer: Convolution reverb
Convolution reverb uses recorded impulse responses (IRs) of real rooms, halls, or hardware units and mathematically convolves them with the audio signal to recreate that space.
