Sampling Rate

Sampling rate refers to how often a signal is measured or sampled within a given period, usually expressed in samples per second (Hz). In audio, for instance, a higher sampling rate means more frequent captures of sound waves, resulting in better quality and more accurate reproduction of the original sound. Common sampling rates include 44.1 kHz for CDs and 48 kHz for video. In essence, sampling rate affects the detail and clarity of digital recordings, whether in music, speech, or other audio formats.
