As part of our quest for the best possible sound we are planning an enhancement 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. Symmetrical 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. * EBC33 - Mullard -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.
