Answer please in order

analogue; discrete; sampled; sample rate; bit depth; bit rate; quality; larger; file size.

Explanation:

Sound are mechanical waves that are highly dependent on matter for their propagation and transmission.

Generally, it travels faster through solids than it does through either liquids or gases.

Sound is a continuously varying, or analogue value. To record sound onto a computer it must be turned into a digital, or discrete variable. To do this, the sound is sampled at regular intervals; the number of times this is done per second is called the sample rate. The quality of the sound depends on the number of bits stored each time - the bit depth. The number of bits stored for each second of sound is the bit rate and is calculated by multiplying these two values (sample rate and bit depth) together - kilobits per seconds (kbps). The higher these values, the better the quality of the sound stored, but also the larger the file size.

that would be my answer.
