Each of us, when loading a new organ sample set will select 24-bit
unless we are limited in our computer RAM. However, is that
necessary or suppose we used lower resolution, say 16 bit or
even 14-bit. What would the result be? We are told lower
signal to noise ratio and a noticeable decrease in sound quality.
Really? Try this listening test where the bit resolution is reduced.
See IF you can determine which track is 24-bit, etc . Resoutiom
is varied between 24-bits and as low as 9-bits.

I'll reveal which is which later. You might follow on here with your results
first. This demonstration first appeared on the Yahoo VTPO group
list.
A very fascinating forum on You Tube about all of this is here:

This Forum runs for nearly an hour, but you might find
the time spent worth while. Note, the first fellow you see and
here in this Forum is the guy who put together the above
BitsTest piece. For the very interesting bit tests, click ahead
in the Forum to the 45 min 10 second point where a similar demo
to the first above is run, but going on down to even 4-bit and
lower resolution.
Note that the first Allen digital generation, their MOS-1 instruments,
used only 8-bit. But also used only a single pipe sample per rank,
and the circuitry only played out 1/2 of the signal wave form; it
was then inverted 180 degrees and played again to form the
complete sample wave! This was caused by the extreme high cost of
digital storage back in 1971. But still, the sound was reasonable,
so Allen sold a lot of MOS-1 organs over the following 10 years.
We ARE very fortunate to now live while this technology has come
so far, and is still advancing!
