Oversampling Explained — Sage Audio

Oversampling is an increasingly common function in most plugins, which increases the sampling rate of the signal it’s processing by a fixed multiple like 2 or 4. So if the sampling rate of your session is 48kHz, a 2x oversampling setting will make the sampling rate 96kHz.
What is oversampling? - Audio Hertz
https://audiohertz.com/2020/01/06/what-is-oversampling/
Oversampling is when a plugin converts the audio to a higher sample rate for processing. Processing at the higher sample rate usually removes some of the negative artifacts associated with processing digital audio; mainly aliasing. Aliasing happens when information outside of the frequency response range of the digital converters and sample ...
What is "Oversampling"?

The data stored on a standard Red Book audio CD is 16-bits, at 44.1 kHz. While oversampling might result in a better A/D conversion when making the CD master, and an oversampling CD player might result in better D/A playback, this is a function of the converters, not the data on the CD.
Upsampling vs. Oversampling for Digital Audio | Audioholics
https://www.audioholics.com/audio-technologies/upsampling-vs-oversampling-for-digital-audio
By sufficiently oversampling at the ADC, we can design a very simple, linear phase, digital filter that has no problems with our audio signal. There has been much misinformation surrounding upsampling and many claims have been made that state that upsampling is necessary to allow for such a desirable digital filter.
Oversampled Peak Detection | Universal Audio
https://www.uaudio.com/blog/oversampled-peak-detection-explained/
For a signal x, which would barely fit on an audio CD, the peak signal value is about 22dB above the largest sample value! The situation is further complicated by the fact that the calculated oversampled peak value depends on the length of window used in the oversampling filter.
Upsampling or Oversampling? | Stereophile.com

In the years since then, the audio industry has settled on an 8x-oversampling ratio, the 44.1kHz CD data being converted to a 352.8kHz datastream before D/A conversion by such popular chips as the Pacific Microsonics PMD-100. Companies like Theta, Wadia, and Krell have used proprietary filter algorithms, but these, too, oversampled the data.
