The standard for tuning in western music has evolved over centuries. A440 is now regarded as the reference pitch. However, not all recordings will necessary conform to that, especially those from the analogue era when producers sometimes used varispeed on the mastering deck if they wanted to alter a recordings tempo.
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.....
