Understanding Sound Representation in Computer Systems

What is the basic definition of sound in terms of physics?

• A visual representation of air pressure

• A digital signal stored in binary

• A vibration that propagates as an audible wave

• A static wave of pressure

What is the process of converting an analog signal into a digital one called?

• Digital to Analog Conversion

• Sound Wave Propagation

• Binary Sound Transformation

• Analog to Digital Conversion

How is the sample rate of a sound wave measured?

• In bits

• In decibels

• In bytes

• In hertz

What happens to the file size when the sample rate increases?

• It increases

• It remains the same

• It decreases

• It becomes zero

What does sample resolution represent in digital sound?

• The number of samples per second

• The number of bits stored with each sample

• The frequency of the sound wave

• The duration of the sound file

How many different amplitudes can a 16-bit sample resolution store?

• 16384

• 1024

• 65536

• 256

What is the effect of increasing the sample resolution on sound quality?

• It decreases the quality

• It has no effect

• It increases the quality

• It makes the sound inaudible

Which formula is used to calculate the file size of a sound sample?

• Sample rate x Sample resolution x Duration

• Sample rate + Sample resolution + Duration

• Sample rate - Sample resolution - Duration

• Sample rate / Sample resolution / Duration

If a sound file has a sample rate of 6 Hz, a sample resolution of 4 bits, and a duration of 3 seconds, what is its file size in bytes?

• 18 bytes

• 9 bytes

• 24 bytes

• 12 bytes

What is the relationship between the number of samples per second and the quality of sound?

• More samples per second have no effect

• More samples per second make sound inaudible

• More samples per second increase quality

• More samples per second decrease quality
