Q: Representing Sound GCSE

Which description most accurately describes ‘Sampling’?

What is meant by the term ‘Bit Depth’?

What will be the difference between a sound file sampled at 100 times per second compared to a sound file sampled at 1000 times per second?

What will be the difference between a sound file with a bitrate of 100kbps compared to a sound file with a bitrate of 1000kbps?

If a sound file had a bit rate of 100kbps and was 100 seconds in length, what would be the size of the file in megabytes?

If a sound was sampled at 320kbps, how many bits of data would there be after 10 seconds?

There are 2 sound files, both 1 min in length. File 1 has a bitrate of 56kbps and a sampling frequency of 31kHz. File 2 has a bitrate of 192kbps and a sampling frequency of 28kHz. Which has the better sound quality?

Sound that has been sampled is also known as…

A higher bitrate means that the samples of sound recorded will be of…

Which of the following files uses compression?
