How does the Nyquist Theorem contribute to audio quality?

The Nyquist Theorem is crucial for maintaining audio quality because it establishes the necessary condition for accurate digital representation of analog signals. Specifically, the theorem states that to faithfully reproduce a sound without distortion, the sampling frequency must be at least twice the highest frequency present in the audio signal.

When audio is digitized, if the sampling rate satisfies this requirement, it captures all the essential details of the sound wave, allowing for accurate representation and playback. Adhering to the Nyquist Theorem prevents aliasing, which occurs when higher frequencies are misrepresented as lower frequencies in a digital recording, ultimately preserving the integrity of the audio. This principle is fundamental in areas such as music recording and playback systems, ensuring that listeners experience sound as it was intended to be heard.

The other options touch on different aspects related to audio technology, but they do not specifically relate to the role of the Nyquist Theorem in ensuring that audio is sampled correctly for high fidelity.
