Wow this is fantastic!! The next step is to implement 128bit @192 KHz
sampling rate in Yoshimi to get crystal audiophile grade hyper harmonics.
And that should hopefully open the path to also have 432 Hz tuning in
Yoshimi.

As part of our quest for the best possible sound we are planning an enhancementYoshimi source code is available from either:
that passes bits through a grading process (the well known 'Enharmonic Bit
Comparator' - version 33)* thus ensuring that any bit asymmetry is removed. In
laymans terms, this has a heater to agitate the bits, then an amplifier to
highlight the errors, and rectifiers to remove them. Symetrical bits produce
significantly less quantum noise so reduce the possibility of alignment
boundary collisions, giving a much warmer, smoother presentation.
Such advanced technology has a cost of course, so to gain the greatest benefit
from this process it is necessary for Yoshimi to now use only audiophile grade
bits, rather than the standard ones and zeros present in ordinary programs. Bit
quality is heavily dependent on the source so we recently did a line-by-line
review of the code, feeding it to our Delta Orthogonal Grader.
Finally, there is the open-source BitShine engine (BS). This 'clarifies'
individual zeroes and ones passing through it, making them sharper, so should
give greater precision when passed on to the DA converter. This is available
under the 'Multi User Grant' license. As it appears to be GPL compatible we are
looking at it for possible inclusion.
I should point out that there is only a narrow window for discussion as we
expect to be committed by lunch time today.
