In fact, high quality audio converters operating at sample rates no higher than 96 KHz offer results that are very close to the desired theoretical limits. Yet, there are many who subscribe to the false notion that operating above the optimal sample rate can improve the audio. The truth is that there is an optimal

Multistage Sample-Rate Conversion of Audio Signals ...

https://www.mathworks.com/help/audio/ug/multistage-sample-rate-conversion-of-audio-signals.html

The sample rate conversion from 96 kHz to 44.1 kHz produces 147 samples for every 320 input samples. Because the chirp signal is generated with frames of 64 samples, an asynchronous buffer is needed. The chirp signal is written 64 samples at a time, and whenever there are enough samples buffered, 320 of them are read and fed to the sample rate converter.

Digital Audio Basics: Audio Sample Rate and Bit Depth

https://www.izotope.com/en/learn/digital-audio-basics-sample-rate-and-bit-depth.html

The sample rate of 44.1 kHz technically allows for audio at frequencies up to 22.05 kHz to be recorded. By placing the Nyquist frequency outside of our hearing range, we can use more moderate filters to eliminate aliasing without much audible effect. Other audio sample rates: 48 kHz, 88.2 kHz, 96 kHz, etc.

2. Open REW, set sample rate to 48 kHz. 3. Play a sweep from 10 kHz to 20 kHz. There are many spurious tones, ascending and descending, throughout the sweep. Sounds like an alien spaceship. Files are attached so you can hear the difference. These were recorded using a loopback in Audacity. You can see there are problems just by looking at the waveform.
