This is nothing but a silly wheeze. If the instruments had been tuned to 432hz, the resulting overtones would have been part of the recording. Simply electronically transposing the recording cannot reproduce something that isn’t there. The whole thing smacks of marketing superstition
Why 432hz Tuning?
A while back I made a post about the 432-EVO streamer and it's ability to convert the signal to 432hz tuning. There was much discussion about why would you convert to 432hz from our current 440hz. This post is not about equipment but this conversion of tuning. I stumbled across this video that offers an excellent observation. This may be a bit deep for some of you and I get it but if you watch the whole thing I think a good argument can be made for 432hz tuning. Oh, and I really don't care if you agree or don't agree or whether you like it or don't like it, I'm merely providing information. Enjoy by removing the spaces.....
