Question 1: What does the 'knee' setting on a compressor control?
- How gradually the compressor transitions from uncompressed to compressed signal (Correct answer)
- The maximum output level of the compressor
- The speed at which the compressor releases gain reduction
- The frequency range affected by compression
Correct answer: How gradually the compressor transitions from uncompressed to compressed signal
The knee setting determines whether compression engages abruptly (hard knee) or gradually (soft knee) as the signal approaches the threshold.
Question 2: In parallel compression, what is blended with the compressed signal?
- The original uncompressed signal (Correct answer)
- A delayed version of the signal
- A high-pass filtered signal
- White noise
Correct answer: The original uncompressed signal
Parallel compression mixes the dry, uncompressed signal with a heavily compressed copy to retain transients while adding sustain and density.
Question 3: What is the typical dynamic range of a commercial pop recording after mastering?
- 6-10 dB (Correct answer)
- 20-30 dB
- 40-50 dB
- 60-70 dB
Correct answer: 6-10 dB
Modern commercial pop masters typically have a dynamic range of about 6-10 dB due to heavy compression and limiting during the mastering process.
Question 4: What happens when you set a compressor's ratio to infinity:1?
- It functions as a limiter, preventing signal from exceeding the threshold (Correct answer)
- It completely mutes the signal
- It inverts the phase of the audio
- It doubles the output gain
Correct answer: It functions as a limiter, preventing signal from exceeding the threshold
An infinity-to-one ratio means no signal passes above the threshold, which is the defining behavior of a brick-wall limiter.
Question 5: Which parameter would you adjust to prevent a compressor from clamping down on every drum transient in a mix bus?
- Increase the attack time (Correct answer)
- Decrease the ratio
- Increase the threshold
- Lower the release time
Correct answer: Increase the attack time
A slower attack time allows the initial transient of each drum hit to pass through before the compressor engages, preserving punch and impact.
Question 6: What is 'gain staging' in the context of dynamic range management?
- Setting appropriate signal levels at each point in the audio chain to maintain headroom and minimize noise (Correct answer)
- Automating volume faders throughout a song
- Applying equal compression to every track
- Boosting the master output to maximize loudness
Correct answer: Setting appropriate signal levels at each point in the audio chain to maintain headroom and minimize noise
Gain staging ensures each device or plugin in the signal chain receives an optimal input level, preserving dynamic range and preventing distortion or excessive noise.
