In digital audio, what is 'dithering' and when should it be applied?
Answer: Adding low-level noise to mask quantization errors when reducing bit depth
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.
What is the primary function of a 'transient shaper' in audio editing?
Answer: To control the attack and sustain characteristics of percussive sounds
A transient shaper independently adjusts the attack (initial impact) and sustain (body) of a sound, making drums punchier or reducing room ambience.
Which audio editing concept describes aligning multiple recorded takes of the same performance to a common timing grid?
Answer: Phase alignment
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.
What does a 'limiter' do differently from a standard compressor?
Answer: It uses a very high ratio (typically ∞:1) to prevent signals from exceeding the threshold
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.
In audio restoration, what does 'spectral repair' allow an editor to accomplish?
Answer: Identifying and removing unwanted sounds from specific frequency ranges at specific times
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.
What is 'gain staging' in the context of a multi-track audio session?
Answer: Setting appropriate signal levels at each point in the signal chain to avoid clipping and noise
Gain staging means managing signal levels at every point in the chain — from clip gain to plugin inputs to faders to the master bus — to keep levels optimal and avoid noise or distortion.
When editing dialogue for a podcast, what is the best practice for handling an unwanted breath between words?
Answer: Reduce the breath's volume with clip gain or automation rather than deleting it entirely
Completely removing breaths sounds unnatural; reducing their level with volume automation or clip gain maintains a natural performance while controlling distracting sounds.
