I think that the idea that you can't tell the difference between 8-bit and 24-bit audio to be rather preposterous. I think that the point that Chucky is making is greatly overstated. I assume that his main point is that the Surround Masters processing power, bit depth and sample frequency ect. are all far in excess of what is actually required.
From my standpoint there is a huge difference between 24-bit and 16-bit audio. While you can take a high rez file and down convert to 16-bit and possibly not be able to discern the difference between them, that misses the point. Negative effects are cumulative (more than just additive). Only by using as high a resolution as possible for our recording and processing can we guarantee a great result. Years ago I did all my recording and processing in 16-bit. My Creative Sound Blaster Audigy sound card was considered state of the art (for home use anyway), my recordings sounded fine. I then went to the Maya 44, also a 16-bit card so that I could record discrete quad. Latter still the Delta 44. With the (24-bit) Delta card the quality of the recordings noticeably improved. I am now using the Digigram VX882HR and can record at sample rates up to 192000, the results are superb!
The argument that high resolution is not required causes me to drift off to a somewhat similar topic. Amplifier distortion below 1% is said to be inaudible. So then it shouldn't be necessary to design audio equipment with specs below that figure? Those high end op-amps with their distortion figures of 0.00003% must be unnecessary overkill so we should just use the venerable 741?
Likewise while I doubt that any golden eared audiophile could hear the difference between a single low quality electrolytic coupling capacitor and an ultra expensive audio grade film capacitor in the same circuit, that does not mean that there is no difference. When a number of such "bad" capacitors are present in a circuit their negative effects cumulate becoming audible.
As for water divining, I believe that it does work. As a child our original water well was dug in a low spot on the property and it regularly went dry. My father wanted to have another well dug. It was suggested that he have someone dowse it first, which he did. The resulting location was near the top of a hill and it has produced an abundance of cool clear water ever since. Some individuals can even dowse for buried electrical cables. Even Albert Einstein believed that dowsing could work! Curious questions: Does water divining actually work? (N.B. Einstein thought it probably did...) - Country Life
