Music & Audio Advice EQ and Frequency Management 1 — Questions and Answers
Question 1: What does EQ stand for in audio production?
- Equalization (Correct answer)
- Electrical Quality
- Equal Quotient
- Electronic Quantizer
Correct answer: Equalization
EQ stands for Equalization, the process of adjusting the balance of individual frequency components within an audio signal.
Question 2: Which frequency range is generally considered 'sub-bass'?
- 250 Hz - 500 Hz
- 500 Hz - 2 kHz
- 20 Hz - 60 Hz (Correct answer)
- 2 kHz - 8 kHz
Correct answer: 20 Hz - 60 Hz
Sub-bass occupies roughly 20–60 Hz, producing the deep, felt-more-than-heard low-end energy in kick drums and bass instruments.
Question 3: A high-pass filter (HPF) allows high frequencies to pass while doing what to low frequencies?
- Boosting them by a fixed amount
- Attenuating frequencies below the cutoff point (Correct answer)
- Adding harmonic distortion to them
- Doubling their amplitude
Correct answer: Attenuating frequencies below the cutoff point
A high-pass filter attenuates (reduces) frequencies below the cutoff frequency, letting only higher frequencies pass through unaffected.
Question 4: What does the 'Q' parameter in a parametric EQ control?
- The overall quality rating of the plugin
- The amount of gain applied in decibels
- The bandwidth (width) of the frequency band being affected (Correct answer)
- The quantization depth of the audio signal
Correct answer: The bandwidth (width) of the frequency band being affected
The Q parameter controls the bandwidth of the EQ band — a high Q creates a narrow, precise boost or cut, while a low Q affects a wider range of frequencies.
Question 5: The 'presence' frequency range, commonly boosted to add clarity and intelligibility to vocals, is typically found around:
- 50–100 Hz
- 1–5 kHz (Correct answer)
- 10–16 kHz
- 100–300 Hz
Correct answer: 1–5 kHz
The 1–5 kHz presence range is where much of a vocal's clarity and articulation lives, and boosting here helps vocals cut through a dense mix.
Question 6: What does a 'low-shelf' EQ do to the audio signal?
- Affects only one specific frequency point
- Boosts or cuts all frequencies above a set point equally
- Boosts or cuts all frequencies below a set point equally (Correct answer)
- Applies EQ only to subwoofer speakers
Correct answer: Boosts or cuts all frequencies below a set point equally
A low-shelf EQ applies a uniform boost or cut to all frequencies below the shelf frequency, making it useful for adjusting overall bass weight.
Question 7: Which EQ type provides independent control over gain, center frequency, and Q for each of its bands?
- Graphic EQ
- Shelving EQ
- Parametric EQ (Correct answer)
- Fixed-band EQ
Correct answer: Parametric EQ
A parametric EQ allows full independent control of gain, center frequency, and Q (bandwidth) for each band, offering the most flexibility in frequency shaping.
