According to Nyquist’s Theorem, for an accurate digital representation of a sound wave, the sample rate must be, at least, two times bigger than the highest frequency going to be recorded. As the highest sound a human can hear has a frequency of 20 kHz, the minimum sample rate must be 40 kHz to be possible to digitalize this frequency.

The Nyquist sampling theorem states that to avoid aliasing the sampling frequency must be at least twice that of the highest frequency which is to be represented. If we return to the example of CD audio, a sampling frequency of 44.1 kHz means that the highest frequency which can be represented without aliasing is 22.05 kHz.

The Nyquist Sampling Rate is known as the minimum sampling rate that can be used without having aliasing. The sampling rate for an analog signal must be at least two times the bandwidth of the signal.. For example, an audio signal with a bandwidth of 50 kHz must be sampled at a frequency of at least 100 kHz to avoid aliasing.

As humans can hear 20–20,000 Hz range; this is why audio waveform and early professional audio equipment manufacturers chose sampling rates at 44.1kHz, the “standard” sampling rate for many digital formats. Increasing the sampling rate generally improves the sound quality, but it also increases the disk space required to store.

The accurate description is that the sampling frequency must be twice the bandwidth of the input signal. In audio, we normally include 0 Hz in the frequency band, making it a baseband signal (think lowpass range down to 0 Hz, rather than a bandpass range), so for our purposes the optimal audio bandwidth we wish to recreate is 0-20,000 Hz, so we may say that a sampling …

the sampling rate must be at least twice as high as the highest frequency you want to represent. One way to think about this is to imagine a high-frequency sine wave for which we sample exactly two points per cycle: the crest (top) of the waveform, and the trough (bottom) of the waveform.
