Question 1

What is the primary advantage of using balanced audio cables (XLR) over unbalanced cables (RCA/TS) in corporate video productions?

Accepted Answer

Balanced cables cancel out electromagnetic interference and noise over long runs

Answer

Balanced cables use two out-of-phase signal lines that cancel common-mode noise when recombined, making them resistant to electromagnetic interference over long cable runs.

Question 2

In corporate video audio, what is 'sync sound'?

Accepted Answer

Audio recorded simultaneously with the video image, intended to be used as the primary sound

Answer

Sync sound refers to audio recorded at the same time as the picture on set, intended to be the primary dialogue and ambient sound used in the final edit.

Question 3

Which type of microphone polar pattern picks up sound equally from all directions and is useful for recording group discussions in corporate video?

Accepted Answer

Omnidirectional

Answer

Omnidirectional microphones pick up sound equally from all directions (360°), making them effective for capturing group discussions, round-table meetings, and ambient sound.

Question 4

What is the role of a 'noise gate' in corporate video audio post-production?

Accepted Answer

It mutes or attenuates audio signals that fall below a set threshold, reducing unwanted background noise between speech

Answer

A noise gate silences audio signals that fall below a defined threshold, effectively removing background noise during pauses in speech or other intended audio.

Question 5

For a corporate video where the presenter will be moving around, which microphone setup is most practical?

Accepted Answer

Wireless lavalier (body pack) microphone system

Answer

A wireless lavalier system transmits audio via radio frequency, allowing presenters to move freely without being restricted by cables while maintaining consistent audio quality.
