whew. left this thread for awhile. got busy.
while i do not entirely agree on some things being said about 432hz, i think this has benefits (with matching cons as well).
as a listener, you don't pull out your tuners and check how these songs are tuned. so on the listener's point of view, it doesn't really matter. anyone would enjoy the music first before anything else.
i remember several occasions when i was younger (when i had no idea or concept of reference pitches). all i know is i used tuners, or if i have no tuner within reach, i would use particular songs for my reference for tuning. and there were times that there were some songs that didn't really "fit like a glove" when i tried playing along with them, that i had to resort to re-tuning my guitar in reference to that particular song. what's worse was i couldn't re-tune my acoustic piano (obviously). so i was puzzled and sometimes disappointed in such a predicament.
on the producing side of things, this would be a major hassle particularly on retuning instruments, especially on pianos and harps (though a workaround would be shifting a sound down by roughly 31 or 32 cents, though that would take away a bit of being "organic" of any sound). if i am not mistaken, i think most of the keyboards / digital pianos have tuning capabilities (mine can do it). i just don't know for MIDI - but i am sure there is a way. but i think most of the advantages lie on the vocalist. it doesn't seem to be much of a difference numerically, but i've worked with several singers who have delivered better on a slightly lower pitch than the standard - this mainly depends on they key of the song and the range of their vocals. and for me it certainly spells the difference between singing at A = 432hz and at G# = 415hz (standard) that i would really take note of.
now that i have been aware of this, i admit that i enjoy hearing some songs at different reference pitches. and i am actually in the middle of producing a song in my band's album at A = 432hz (amidst of everything else recorded at A440), but it does not work on everything. heck some songs would be sounding better at an even lower reference pitch, or maybe a higher one. i don't know if you guys would agree with me but i think we are just clamped down to this standard A440 for the sake of convenience (well the way how most popular instruments are designed - a standard would be a need at some point). as
Everdying has mentioned, tuning is relative - and that includes also all frequencies in between the standards.

i've heard of this before...
but i think it only applies in the standard tuning we all are familiar with?
if you're talking about the 12-tone equal temperament (standard chromatic?), then i'd say yes it applies to that

but i guess in the end, tuning is relative...and as long as the whole band is in tune...no harm trying...
just that in future should someone else try to dictate ur stuff, they would just say u are slightly flat

hope they bring their tuners with them
