What is the primary purpose of converting analogue sound to digital format?
To increase the volume of the sound
So the analogue sound can be saved and used by digital devices.
To make the sound more natural
To change the pitch of the sound
Which of the following best describes the term "sample rate" in digital audio?
The number of bits used to represent each sample
The number of times per second the amplitude is measured
The duration of the audio file
The frequency of the sound wave
What is "bit depth" in the context of digital audio?
The number of samples taken per second
The number of bits used to represent each audio sample
The length of the audio file in seconds
The speed at which the audio file is played
How does increasing the sampling rate affect the quality of digital audio?
It decreases the file size
It increases the file size and improves audio quality
It has no effect on audio quality
It decreases the audio quality
Which of the following is a property of sound waves?
Amplitude
Bit rate
File format
Compression ratio
What does an analogue-to-digital converter (ADC) do?
It converts digital signals to analogue signals
It converts analogue signals to digital signals
It compresses audio files
It increases the volume of audio files
Which unit is commonly used to measure the sampling rate of digital audio?
Hertz (Hz)
Decibels (dB)
Bits per second (bps)
Kilobytes (KB)
What is the effect of increasing the bit depth in digital audio?
It decreases the file size
It increases the file size and improves the sound quality
It reduces the dynamic range
It has no effect on audio quality
