Sound Fun

Reorder the following

• You give it a numeric value based on its amplitude/loudness

• This number is then turned into a piece of binary data 1s and 0s.

• You record a sound sample

Reorder the following

• Turn the value into digital data so it can be stored on the computer.

• Check its amplitude and give it a value

• Measure the sound sample

Sound waves in nature have a continuous or analogue form. Computer systems can only store distinct values, i.e. sequences of _s and 0s. Therefore, sound needs to be converted into a digital format to be processed by a computer.

Sound waves in nature have a continuous or analogue form. Computer systems can only store distinct values, i.e. sequences of 0s and 1s. Therefore, sound needs to be converted into a _________ format to be processed by a computer.

First, sound is recorded using a __________ (e.g. a microphone) that can turn sound waves into an electrical signal. Then, measurements of the level of the signal, called samples are taken at regular intervals.

Sampling rate is defined as the number of _________ taken per second. It is measured in hertz (one hertz is equal to one sample per second)
