Question 1

With digital recording, the sound is measured and converted into mathematical units.

Accepted Answer

With digital recording, sound is first measured by an analog-to-digital converter, which converts the analog signal (sound waves) into mathematical units called "samples." These samples are then stored as digital data, allowing for accurate reproduction of the original sound.

Question 2

A volume unit (VU) meter measures amplitude.

Accepted Answer

A volume unit (VU) meter measures the amplitude or strength of an audio signal. It is commonly used in audio production and broadcasting to ensure that levels are within acceptable limits and to prevent distortion.

Question 3

An LED meter measures ambient noise.

Accepted Answer

An LED meter measures the level of light, not ambient noise. A sound level meter or SPL meter would be used to measure ambient noise.

Question 4

DVDs are sometimes used in audio production since they can hold a lot more data than a CD.

Accepted Answer

DVDs have a higher data storage capacity than CDs, making them useful in certain audio production situations where a larger amount of data needs to be stored.

Question 5

The Golden Age of radio broadcasting began in the 1920s, but had played out by World War II.

Accepted Answer

The Golden Age of radio broadcasting began in the 1920s and continued through the 1940s, with many of the most popular shows and broadcasts occurring during World War II.
