Understanding Sound in Digital Media

What is bit depth in digital audio?

• The number of times audio is sampled per second

• The number of bits used to represent each audio sample

• The frequency range of the audio

• The duration of the audio file

How does increasing the bit depth affect audio quality?

• It decreases the file size

• It increases the dynamic range

• It reduces the sampling rate

• It has no effect on audio quality

What is sample frequency in digital audio?

• The number of bits used per sample

• The number of samples taken per second

• The length of the audio file

• The amplitude of the sound wave

Why is a higher sample frequency important in digital audio?

• It reduces the file size

• It captures more detail in the sound

• It decreases the bit depth

• It shortens the audio duration

How is sound represented in binary form?

• As a series of 0s and 1s

• As a series of letters

• As a series of decimal numbers

• As a series of hexadecimal numbers

What is the effect of increasing the sampling rate on audio quality?

• It decreases the dynamic range

• It increases the frequency range captured

• It reduces the bit depth

• It has no effect on audio quality

What is the main difference between digital and analogue sound?

• Digital sound is continuous, analogue is discrete

• Digital sound is discrete, analogue is continuous

• Digital sound is louder, analogue is quieter

• Digital sound is quieter, analogue is louder

Which of the following is a benefit of digital sound over analogue sound?

• Digital sound is more susceptible to noise

• Digital sound can be easily copied without loss of quality

• Digital sound requires more storage space

• Digital sound is harder to edit

What happens to the file size when the bit depth is increased?

• The file size decreases

• The file size increases

• The file size remains the same

• The file size becomes unpredictable

How does a higher bit depth affect the dynamic range of audio?

• It decreases the dynamic range

• It increases the dynamic range

• It has no effect on the dynamic range

• It makes the dynamic range unpredictable
