Where did 192 KHz come from? Why is anybody interested in anything that far over 2*44 KHz? It's common to have an audio ADC run much faster than Nyquist, but that's a hack to make it easier to build the cut off filter. You build a simple analog filter and a sharp digital filter and decimator so the output is 2x the target frequency. You get what you want without a fancy analog filter. -- These are my opinions.
