Audio Editing Audio Editing MCQ 3

Question 1

In digital audio, what is 'dithering' and when should it be applied?

Accepted Answer

Adding low-level noise to mask quantization errors when reducing bit depth

Answer

Dithering adds a small amount of shaped noise to randomize quantization errors when reducing bit depth (e.g., from 24-bit to 16-bit), preserving perceived audio quality.

Question 2

What is the primary function of a 'transient shaper' in audio editing?

Accepted Answer

To control the attack and sustain characteristics of percussive sounds

Answer

A transient shaper independently adjusts the attack (initial impact) and sustain (body) of a sound, making drums punchier or reducing room ambience.

Question 3

Which audio editing concept describes aligning multiple recorded takes of the same performance to a common timing grid?

Accepted Answer

Phase alignment

Answer

Phase alignment (or timing alignment) ensures that multiple takes, overdubs, or mic placements are time-aligned so their waveforms don't cancel or comb-filter each other.

Question 4

What does a 'limiter' do differently from a standard compressor?

Accepted Answer

It uses a very high ratio (typically ∞:1) to prevent signals from exceeding the threshold

Answer

A limiter is essentially a compressor with an extremely high ratio (often ∞:1), acting as a hard ceiling that prevents signals from exceeding the set threshold.

Question 5

In audio restoration, what does 'spectral repair' allow an editor to accomplish?

Accepted Answer

Identifying and removing unwanted sounds from specific frequency ranges at specific times

Answer

Spectral repair tools (like those in iZotope RX) let editors visually select and remove clicks, pops, or specific noises from exact time-frequency areas on a spectrogram.
