- 2How do computers store sound?They must convert analogue sound waves into digital values to store sound
- 3What is used for this process?An analogue to digital converter
- 4What is sampling?The process of recording sound and storing it digitally
- 5What is the sample rate?The frequency at which the sound is sampled, or measured
- 6What happens the more frequently the sound is sampled?The more accurate the recording of the sound is to what you hear
- 7What is the digitally stored sound presented as?Binary
- 8The greater the number of bits used to store the samples, _____The more detailed each of the samples are
- 9What is the bit depth?It describes the number of bits used to store each sample
Sometimes referred to as Sample Resolution - 10What is sound synthesis?The term used to describe the process of taking digital sound files and playing through a speaker in a way that we can hear
- 11What is interpolation?A process used to 'fill in the gaps' between samples and produce a more complete sound
