Bob,

It is possible. Just select the part you want to covert, then go to 
Effect / Change pitch and select the initial and final tuning frequency. 
Note that not necessarily the original tuning is 440 Hz. Particularly, 
much youtube music has a slight pitch shift to circumvent copyright 
violation prosecution.

This method may exhibit artifacts. If you are good with a slight tempo 
change, you can use resampling from Effect / Change speed, selecting 
432/440 = 1,0189 as speed multiplier. Resampling renders a better result 
for complex musical textures such as symphonic.

However you should be aware that most writings supporting 432 Hz vs. 440 
Hz are just nonsense. There is nothing special about 432 Hz tuning. No 
synchronization with the Universe or the ADN or the like. The second, as 
a unit of time, is an arbitrary unit and so is the Hz, so if there were 
a true frequency that is better than all other frequencies, the odds 
that it would be represented as a beautiful whole number such as 432 Hz 
are vanishingly small. If the exact perfect tuning were, say, 
432,1723... Hz, then using an exact value of 432 Hz would actually 
prevent any true synchronization since the phase between the vibration 
of the air caused by the sound source and the vibration of the Universe 
would slide permanently, oscillating between complete synchronization 
and complete desynchronization about each three seconds (in this 
example). Should that synchronization be important, it is clear that the 
situation would be, to say the least, distressing.

On the other hand, it would be almost impossible to ensure that the 
tuning is accurate enough to accomplish the alleged synchronization or 
whatever effect is sought.

Another concern is that our occidental chromatic scale uses uniform 
temperament, this means that the interval between a note like A and the 
next semitone, say A sharp is obtained by multiplying by the twefth root 
of 12, which is a irrational number, so may be the A 432 Hz vibrates 
with the Universe, but no other single note will be any closer to any 
relevant sychronization. If we used a natural scale there would be more 
chances that at least some harmonics of other notes could also 
synchronize...

So neither A 432 Hz is the best frequency nor A 440 Hz is an evil tuning 
designed by the nazis, as a conspiracy theory maintains.

Regards,

Federico Miyara
