Digital Representation of Sound Quiz

What is the purpose of converting continuous analogue sound data into discrete digital data?

• To provide a better representation of the original sound

• To reduce the file size

• To improve the quality of the sound

What does the sample rate determine in the quality of the recorded sound?

• The duration of the sound

• The amplitude of the sound wave

• The accuracy of the representation

How does a higher sample rate affect the file size of a sound recording?

• It increases the file size

• It decreases the file size

• It depends on the bit depth

What does the bit rate represent in the storage of sound data?

• The number of bits used to store one second of sound

• The number of channels in the sound

• The duration of the sound

How does increasing the bit rate affect the file size of a sound recording?

• It decreases the file size

• It depends on the sample rate

• It increases the file size

What have the lessons in section 1.2.4 covered?

• Numbers, colors, and shapes

• Characters, images, and sound
