Detailed explanation-1: -If lower sampling rates are used, the original signal’s information may not be completely recoverable from the sampled signal or it may result in an audible artifact known as “aliasing.” (We’ll talk more about aliasing later in this article.)
Detailed explanation-2: -Sample rate is the frequency at which snapshots of an analog signal are recorded. Thus the more snapshots per second, the higher the sample rate and the better the quality.
Detailed explanation-3: -The higher the sampling rate, the more accurate the sound wave representation will be. Lower sampling rates mean fewer samples per second. With less audio data, the audio representation will be approximate, to some extent. The most common sampling rate values are 44.1 kHz and 48 kHz.
