Free Audio Editing MCQ Question and Answers

Question 1

A limiter is described as

Accepted Answer

a compressor with a ratio that is 10:1 or higher

Answer

A limiter is essentially a type of compressor with a very high compression ratio, typically 10:1 or greater, often approaching infinity:1. Its primary function is to prevent an audio signal from exceeding a certain threshold, effectively 'limiting' its peak amplitude and preventing clipping or distortion. This makes it a crucial tool for mastering and ensuring consistent loudness.

Question 2

On a keyboard, what is the frequency connection between two notes that are an octave apart?

Accepted Answer

Half/Double

Answer

In music and acoustics, two notes that are an octave apart have a fundamental frequency ratio of 2:1. This means the higher note in an octave pair has exactly double the frequency of the lower note, and conversely, the lower note has half the frequency of the higher note. This fundamental relationship defines the octave interval.

Question 3

The tweeters of near-field speakers should be positioned so that they are

Accepted Answer

at ear level

Answer

For optimal stereo imaging and frequency response, near-field monitors should be positioned so that their tweeters are at the listener's ear level. This ensures that the high frequencies, which are more directional, are aimed directly at the ears, providing the most accurate and balanced sound reproduction. Proper speaker placement is crucial for critical listening.

Question 4

What audio issue is treated by reversing polarity?

Accepted Answer

Phase Misalignment

Answer

Reversing polarity (or inverting phase) is a technique used to correct phase misalignment issues between two or more audio signals. When signals are out of phase, their waveforms can partially cancel each other out, leading to a thin sound or frequency loss. Flipping the polarity of one signal can bring them back into alignment, restoring fullness and clarity.

Question 5

When, for instance, a loud cymbal crash and a softer fragment of human speech appear simultaneously in a mix, the speech becomes less understandable due to a psychoacoustic phenomenon known as:

Accepted Answer

Masking

Answer

Masking is a psychoacoustic phenomenon where the perception of one sound is affected by the presence of another sound. In this scenario, the loud cymbal crash 'masks' the softer speech, making it harder to hear or understand because the louder sound effectively covers up the quieter one within the auditory system. This is a common challenge in audio mixing.
