What is the difference between oversampling and non oversampling?

What is the difference between oversampling and non-oversampling? The main difference is that oversampling increases its sample rate, whereas non-oversampling bypasses the increasing step and converts the digital signal to analog in its original form. Oversampling and non-oversampling (NOS) are two approaches in digital-to-analog conversion (DAC) for audio reproduction. Oversampling processes digital audio data by increasing its sampling rate before conversion, improving filtering, and reducing noise. On the other hand, non-oversampling skips this step, delivering a real, unprocessed signal that, according to some audiophiles, retains a more "natural" sound. Explanation: Are you a digital audio lover? As we know, when it comes to digital audio playback, the role of the DAC is critical. I know that you all already kno,w but still, a short intro that the DAC converts digital signals into analog sound that we can hear. The way this conversion is handled—either through oversamp...
