Thanks for the info Steven, this will be interesting to "play" with. I'm always open to a testable new idea (i.e. swedishme's remarks), and then drawing my own conclusions.
For anyone's interest, that tuning pitch (432hz) is done by doing pitch adjust to -0.32 (exact -0.3176) in semitones, -31.766 in cents. Alternately, the same effect is claimed by doing a playback rate (NOT tempo) adjust of -1.82% (exact is -1.818%), or .98182 X, depending on what scale is provided. I tried the pitch method in another player but it resulted in noticeable audio "artifacts" so the testing ended, ahem, immediately; that player however did not use the BASS libraries.
