Only problem is that 192 kHz serves no purpose. No musical instrument produces over 70 kHz. Not only that, but as stated in Dan Lavry's 'Sampling Theory For Digital Audio
There is an inescapable tradeoff between faster sampling on one hand and a loss of accuracy,
increased data size and much additional processing requirement on the other hand.
AD converter designers can not generate 20 bits at MHz speeds, yet they often utilize a circuit
yielding a few bits at MHz speeds as a step towards making many bits at lower speeds.
The compromise between speed and accuracy is a permanent engineering and scientific
Sampling audio signals at 192KHz is about 3 times faster than the optimal rate.
It compromises the accuracy which ends up as audio distortions.
While there is no up side to operation at excessive speeds, there are further disadvantages:
1. The increased speed causes larger amount of data (impacting data storage and data
transmission speed requirements).
2. Operating at 192KHz causes a very significant increase in the required processing
power, resulting in very costly gear and/or further compromise in audio quality.
The optimal sample rate should be largely based on the required signal bandwidth. Audio
industry salesman have been promoting faster than optimal rates. The promotion of such ideas
is based on the fallacy that faster rates yield more accuracy and/or more detail. Weather
motivated by profit or ignorance, the promoters, leading the industry in the wrong direction, are
stating the opposite of what is true.
24/96 is all you need at max
. You can't reproduce things that aren't there in the first place!
In a practical sense, 96 kHz sampling rate is useful to capture every sound, including ultrasonics, in a recording [unless you are recording whales communicating with one another) and 24 bit is useful for VST use and if you use the digital volume control a lot, as lowering the digital volume control sheds off bits (1 bit = every ~6 dB). As the old saying goes: Record at 24/96, playback at 16/44.1.
It's the same as anything over 120Hz / 120 FPS serves no purpose for 'smoothness' ala motion detection for gaming or video due human physical limits. An eagle will notice the difference, not you. And men have greater motion detection on average than women, while women have greater colour perception on average.
