Music & Audio Advice Mixing and Mastering Principles 2 — Questions and Answers
Question 1: What is the primary purpose of a high-pass filter on a vocal track in a busy mix?
- Add high-frequency sparkle
- Remove low-frequency rumble and mud to clear headroom (Correct answer)
- Increase overall vocal volume
- Add reverb tail
Correct answer: Remove low-frequency rumble and mud to clear headroom
A high-pass filter cuts unneeded low frequencies, reducing mud and freeing up space for the bass and kick.
Question 2: Which technique reduces frequency masking between two instruments competing in the same range?
- Complementary (subtractive) EQ (Correct answer)
- Boosting both at the same frequency
- Hard panning both to center
- Adding identical reverb
Correct answer: Complementary (subtractive) EQ
Cutting a frequency on one instrument where you boost it on another lets each occupy its own space.
Question 3: What does a compressor's 'attack' control determine?
- How loud the output is
- How quickly gain reduction engages after the threshold is crossed (Correct answer)
- The frequency being compressed
- How long the reverb lasts
Correct answer: How quickly gain reduction engages after the threshold is crossed
Attack sets how fast the compressor clamps down once the signal exceeds the threshold.
Question 4: Why is gain staging important before mixing?
- It makes tracks louder for streaming
- It keeps signal levels healthy to avoid clipping and preserve headroom (Correct answer)
- It adds harmonic distortion
- It replaces the need for a limiter
Correct answer: It keeps signal levels healthy to avoid clipping and preserve headroom
Proper gain staging keeps each stage in its optimal range, preventing clipping and noise buildup.
Question 5: What is the typical role of panning in a stereo mix?
- Control loudness
- Place sounds across the stereo field to create width and separation (Correct answer)
- Add low-end weight
- Set the tempo
Correct answer: Place sounds across the stereo field to create width and separation
Panning positions elements left-to-right, improving clarity and stereo width.
Question 6: Which element is usually kept centered (mono) in most mixes?
- Lead vocal, kick, snare, and bass (Correct answer)
- Hi-hats
- Background pads
- Overhead cymbals
Correct answer: Lead vocal, kick, snare, and bass
Low-end and lead elements are centered for mono compatibility and a solid foundation.
Question 7: What is the main goal of mastering as opposed to mixing?
- Balance individual tracks within a song
- Finalize and polish the full stereo mix for consistency and loudness across a release (Correct answer)
- Record new instruments
- Tune vocals
Correct answer: Finalize and polish the full stereo mix for consistency and loudness across a release
Mastering optimizes the finished stereo mix for translation, loudness, and cohesion across playback systems.
