Question 1

What is the effect of setting a compressor's 'release time' too short on a mix?

Accepted Answer

It can cause audible 'pumping' or 'breathing' as the gain rapidly recovers

Answer

A very short release causes the compressor to rapidly restore gain after each transient, creating an audible pumping artifact as the gain repeatedly surges and falls.

Question 2

When editing audio for broadcast in the US, which loudness standard is most commonly required?

Accepted Answer

ATSC A/85 (-24 LKFS integrated)

Answer

ATSC A/85 specifies a target of -24 LKFS integrated loudness for US broadcast television, mandated to prevent jarring volume differences between programs and commercials.

Question 3

What is a 'room tone' and why is it recorded on professional audio productions?

Accepted Answer

The natural ambient sound of a recording location, used to fill gaps and maintain continuity in edits

Answer

Room tone is a recording of the ambient silence of a location; editors use it to fill cuts and transitions so the background sound doesn't abruptly drop to dead silence.

Question 4

In audio post-production, what does ADR stand for?

Accepted Answer

Automated Dialogue Replacement

Answer

ADR (Automated Dialogue Replacement) is the process of re-recording dialogue in a studio to replace unusable production audio, with actors syncing their performance to picture.

Question 5

Which audio editing technique is used to remove the click or pop caused by a waveform not crossing zero at an edit point?

Accepted Answer

Using zero-crossing snapping or applying a short crossfade at the edit point

Answer

Edit clicks occur when a waveform is cut at a non-zero amplitude point; snapping cuts to zero-crossings or adding a short crossfade smoothly transitions between clips and eliminates the pop.
