| Keyword | Definition |
|---|---|
| limitation | lack of quality in a digital sound recording |
| resolution | the number of bits use to store each sample. A lower number means fewer levels of amplitude available to represent the audio recording which means a smaller file size but lower quality. |
| sampling frequency | the number of samples stored each second. A lower number means fewer samples stored per second which means a smaller file size but lower quality. |
