From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

That is not what 96khz means. It doesn't just mean it can store frequencies up to that frequency, it means that there are 96,000 samples every second, so you capture more detail in the waveform.
Having said that I'll give anyone £1m if they can tell the difference between 48khz and 96khz. 96khz and 192khz should absolutely be used for capture but are absolutely not needed for playback.
It means it can capture any frequency up to half the sample rate, perfectly. The "extra detail" in the waveform is higher frequencies beyond the range of human hearing
That is what it means. Any detail in the waveform that is not captured by a 48kHz sample rate is due to frequencies that humans can't hear.
this is a misconception about how waves are reconstructed. each sample is a single point in time. But the sampling theorem says that if you have a bunch of discrete samples, equally spaced in time, there is one and only one continuous solution that would hit those samples exactly, provided the original signal did not contain any frequencies above nyquist (half the sampling rate). Sampling any higher than that gives you no further useful information. There is stil only one solution.
tldr: the reconstructed signal is a continuous analog signal, not a stair step looking thing
