The sampling frequency or sampling rate, fs, is the average number of samples obtained in one second, thus fs = 1/T. Its unit is sample per second or hertz e.g. 48 kHz is 48,000 samples per second. Reconstructing a continuous function from samples is done by interpolation algorithms.

What is meant by sampling frequency?
Sampling rate or sampling frequency defines the number of samples per second (or per other unit) taken from a continuous signal to make a discrete or digital signal.
Why is sampling frequency important?
If the signal contains high frequency components, we will need to sample at a higher rate to avoid losing information that is in the signal. In general, to preserve the full information in the signal, it is necessary to sample at twice the maximum frequency of the signal.
What sampling frequency should I use?
Overall, recording at 44.1kHz is a safe option that will provide you with high-quality recordings, regardless of the type of audio project you're working on. 44.1kHz is the most common sample rate for music CDs. It captures the entire audible frequency spectrum accurately.
