The 192 is really for low latency not for anything you can actually hear. You can't hear the difference past 48khz. An audio interface that can do 192 gets you down to 5ms latency where you can finger drum without being thrown off. But it has nothing to do with audio quality. Like if you use guitar rig you will have the lowest possible latency for realtime computer generated guitar effects at 192.

Where do you get the 5ms from? Why is 192 more likely to have lower latency? I would think the higher bandwidth required by 192 has the possibility to slow your computer down and cause more latency.

  I believe the parent might be referring to the myth about attack of signal falling "between the cracks" of digital sampling. This is debunked in the video linked elsewhere, in the chapter titled "bandlimitation and timing". I might be wrong about the parent poster's meaning, though.

  I believe the parent is referring to the latency of real-time effects used during performance: * With analogue equipment the latency between the input and output of the effect is often below 1 ms (unless the effect is supposed to have a delay). * Standalone digital effect equipment that processes the samples one at a time can also have a latency below 1 ms. (48kHz ≈ 0.02 ms) * If you use a computer for real-time effects, the samples are not transferred sample by sample from the audio interface, but in a block of many samples. The number of buffers and the size of them can usually be changed by the user. With a buffer of 1024 samples, the oldest sample is already about 21 ms old before the computer can process it. After the buffer is processed it has to be transferred to the audio interface, and that will add another 21 ms. So the minimum latency for any real-time effect in the computer is about 42 ms at 48 kHz if the size of the buffers is 1024 samples. Often it is much worse because the operating system adds more latency. If the equipment can handle a sample rate of 192 kHz, the same latency is about 10 ms. If the computer can handle smaller buffers, the latency can be lowered. With 256 samples per buffer the minimum latency will be about 11 ms at 48 kHz and 3 ms at 192 kHz.
