if you don't know what the original was tuned to, how will you know how much to change the pitch by so as to tune it to "A 432"?
More importantly, how will you know if it really is tuned to "A 432" and not, say "A 415"?

I think the proponents of the 432 Hz doctrine know that all they can reasonably recommend is to apply a Pitch change of -1.818% (because the music was tuned to 440 Hz in the first place and you can't undo that).

If it's important to you, look at a score for the song you are interested in, select an individual note in the waveform (a solo instrument or voice would be best) then look to see what pitch Change Pitch thinks that note is. Write down the percentage change needed to make that note the pitch the score says it is. Cancel Change Pitch, select all the song, open Change Pitch then apply the percentage change you wrote down. Then do your -1.818 % change on the entire audio.

You won't achieve what you thought you would achieve but at least you will know you have the song in the correct key and at 1.818 % lower pitch.

The best way to re-tune a piece is to search for a MIDI version.
Those songs can not only be transposed but have their own tuning scale.

I've tried some of the various tunings (there are a lot) on some pre-Bach "Spinett" pieces.
It's a remarkable difference since the fifth are very strong (natural tuning), when played in the right key. If not, you'll experience the famous "Wolfs-Quint" or in other words, the Pythagorian Comma.

The thing that I find so ironic about the whole issue of "432 Hz tuning" is that proponents of this frequently claim that the "A 440" standard was invented by the Nazis in 1939, and that "A 432" tuning was popularised by Verdi (1813 - 1901). Both of those statements are myths created by the American political extremist Lyndon LaRouche (1922 - present), who is considered by many to be a neo-fascist and anti-Semite. These myths are actively promoted by the "Schiller Institute", a German political organisation founded by Helga Zepp-LaRouche (wife of Lyndon LaRouche) in 1984.

This post really is off-topic, but the answer to the original question has already been given (use "Change Pitch" or "Change Speed" with "Percent change = 1.818").
I'll not post links to support the statements above - they are all well documented facts that can be easily confirmed by historical records.

How can I put a song in 2 hz ? Thank You, please help!

Mario,

This is a very old thread... What are you REALLY trying to do???

How can I put a song in 2 hz ?

No...

1. A song doesn't have a single-frequency. There are always harmonics and most music contains several simultaneous notes-frequencies. Normal music is tuned to A = 440Hz so all of the musicians can play in-tune. There is another 'A' at 220Hz and 880hz, etc. I believe there are 8 A-notes on the piano. But a particular song may not have any A-notes, depending on the key & scale of the song.

2. 2Hz is not "sound". It's below the range of hearing. And, it's very difficult to reproduce such a "soundwave"...

You can generate a 2-Hz wave and if your sound system can pass it through to your speakers you'll probably see the woofer move at 2-cycles per second, but if you hear anything at all you'll be hearing distortion. (And, if you have a high-power amplifier you might fry your speaker.)
