Music & Audio Advice EQ and Frequency Management 2 — Questions and Answers
Question 1: What is 'frequency masking' in the context of mixing?
- Applying a noise gate to suppress unwanted frequencies
- When one sound obscures or hides another sound in the same frequency range (Correct answer)
- The process of filtering out audio artifacts using a mask plugin
- Using compression to control frequency peaks dynamically
Correct answer: When one sound obscures or hides another sound in the same frequency range
Frequency masking occurs when two sounds sharing the same frequency range compete, causing one to drown out the other and reducing overall clarity in the mix.
Question 2: Which technique involves cutting a narrow frequency band from one instrument to create space for another instrument occupying the same range?
- Frequency stacking
- Sidechain compression
- Additive EQ
- Subtractive EQ (frequency carving) (Correct answer)
Correct answer: Subtractive EQ (frequency carving)
Subtractive EQ, or frequency carving, cuts unwanted or competing frequencies from one instrument so that another instrument can be heard more clearly in that range.
Question 3: What does 'additive EQ' refer to in mixing practice?
- Chaining multiple EQ plugins in series for cumulative effect
- Boosting certain frequencies to enhance desired tonal characteristics (Correct answer)
- Removing resonant frequencies to reduce harshness
- Adding a low-pass filter to the master bus
Correct answer: Boosting certain frequencies to enhance desired tonal characteristics
Additive EQ means boosting frequencies to emphasize certain tonal qualities, as opposed to subtractive EQ which involves cutting unwanted frequencies.
Question 4: 'Mud' or 'muddiness' in a mix is most commonly caused by a buildup of energy in which frequency range?
- 8 kHz – 16 kHz
- 200 Hz – 500 Hz (Correct answer)
- 60 Hz – 80 Hz
- 3 kHz – 6 kHz
Correct answer: 200 Hz – 500 Hz
The 200–500 Hz range is the primary source of 'mud' — excessive energy here from multiple instruments can make a mix sound thick, unclear, and lacking definition.
Question 5: What is the primary purpose of boosting 'air' frequencies (approximately 12–16 kHz) during mixing or mastering?
- To add warmth and body to the low end
- To remove harshness from cymbals
- To add openness, sparkle, and airy presence to a mix (Correct answer)
- To increase the perceived bass response of the track
Correct answer: To add openness, sparkle, and airy presence to a mix
A gentle shelf boost in the 12–16 kHz 'air' band adds an open, airy shimmer to a mix, making it sound more spacious and polished without introducing harshness.
Question 6: When EQ'ing a kick drum, which frequency range typically controls the 'attack,' 'click,' or 'snap' of the beater hit?
- 20–60 Hz
- 3–5 kHz (Correct answer)
- 10–12 kHz
- 800 Hz – 1 kHz
Correct answer: 3–5 kHz
The 3–5 kHz range on a kick drum captures the beater click or snap, which is responsible for the transient attack that cuts through a dense mix.
Question 7: What is the main advantage of a 'linear phase EQ' over a 'minimum phase EQ'?
- It uses significantly less CPU processing power
- It applies more aggressive filter curves for stronger cuts
- It introduces no phase shift, preserving transient integrity (Correct answer)
- It automatically adjusts gain based on input signal level
Correct answer: It introduces no phase shift, preserving transient integrity
Linear phase EQ processes audio without introducing any phase shift at EQ'd frequencies, which is especially important on the master bus or when phase coherence between tracks matters.
