Question 1

What is the primary purpose of a high-pass filter during mixing?

Accepted Answer

To remove unwanted low-frequency rumble and mud

Answer

A high-pass filter attenuates frequencies below a set cutoff point, cleaning up low-end rumble and muddiness from tracks that don't need bass content.

Question 2

What does the term 'gain staging' refer to in mixing?

Accepted Answer

Setting proper signal levels at each point in the audio chain to avoid distortion and noise

Answer

Gain staging is the practice of managing signal levels at every point in the processing chain to maintain headroom and minimize noise or clipping.

Question 3

In mastering, what is the purpose of a limiter on the master bus?

Accepted Answer

To set a ceiling that prevents the audio from exceeding a specified peak level

Answer

A limiter sets an absolute ceiling for peak levels, preventing digital clipping while allowing the overall loudness to be increased.

Question 4

What is the Fletcher-Munson curve and why is it relevant to mixing?

Accepted Answer

It describes how human hearing perceives different frequencies at different volumes

Answer

The Fletcher-Munson curve (equal-loudness contour) shows that human ears are less sensitive to low and high frequencies at lower volumes, which affects mixing decisions at different monitoring levels.

Question 5

What is parallel compression and when is it commonly used?

Accepted Answer

Blending a heavily compressed signal with the dry original to add punch while preserving dynamics

Answer

Parallel compression mixes a heavily compressed copy of a signal with the unprocessed original, adding sustain and density while retaining natural transients and dynamics.
