Question 1

What is 'bit depth' in digital audio and how does it affect recordings?

Accepted Answer

The number of bits per sample, which determines dynamic range and noise floor

Answer

Higher bit depth provides more amplitude resolution, resulting in lower noise floor and greater dynamic range; 24-bit (144 dB theoretical range) is standard in professional recording.

Question 2

What does 'gain staging' mean in audio production?

Accepted Answer

Optimizing signal levels at each stage of the signal chain to avoid distortion and maximize signal quality

Answer

Proper gain staging ensures that signal levels stay in an optimal range—loud enough to avoid noise but not so loud as to clip—at every point from mic preamp through mixing and mastering.

Question 3

Which editing technique involves placing audio clips precisely on the grid to correct timing?

Accepted Answer

Quantization or grid-snap editing

Answer

Quantization snaps audio clips or MIDI notes to the nearest grid division, correcting timing inconsistencies relative to the tempo.

Question 4

What is a 'crossfade' used for when editing audio clips?

Accepted Answer

To create a smooth transition between two adjacent audio clips by overlapping and blending their edges

Answer

A crossfade overlaps the end of one clip with the start of the next, fading one down while the other fades up to eliminate clicks and create seamless edits.

Question 5

In spectral editing, what can an editor do that standard waveform editing cannot?

Accepted Answer

Remove or repair sounds at specific frequencies without affecting the rest of the audio

Answer

Spectral editing displays audio as a frequency vs. time spectrogram, allowing surgical removal of individual sounds like coughs or squeaks at their specific frequency and time location.
