| Sound wave | an audible vibration that travels through air or water. |
| Frequency | Number of waves to pass a point in one second. |
| Amplitude | Distance from rest to crest to rest to trough. |
| Wavelength | Distance from crest to crest. |
| Crest | Point that exhibits maximum amount of upward displacement from the rest position. |
| Trough | Point that exhibits maximum amount of download displacement from the rest position. |
| Pitch | The quality of the sound determined by the rate of vibration. |
| Sampling | process used to convert analog sound waves into digital data to be used by computers. |
| Sample rate | the number of samples taken per second, often measured in Kilohertz (kHz). |
| Bit rate (Depth) | the number of computer bits process per unit of time. |
| Sample size | the number of bits used to save one sample. |
| Channel | single audio stream consisting of a sequence of samples. |
| Mono | one channel; audio is a single channel, where sound comes from a single direction. |
| Stereo | two channels; creates the impression of sound being heard from various directions, as in human hearing. |
| Audio file size | determined by the sample rate, sample size and number of channels used. |
