Frequency / Pitch change.
Hi.
I’m a clinical hypnotherapist and want to make recordings for my clients.
I need to have my voice at a frequncy to be unaudible to the human ear, but will still be picked up on a subconscious level. i.e. subliminal messaging.
Can anyone tell me how I can achieve this please.

You’ll need begin by recording a voice that you can’t hear.
but. I’m sure you’re aware that the normal human hearing range falls between 20hz and 20khz and that the human voice frequencies are strongest around 7kh. Try recording your voice and then play around with n-T’s graphic eq. As you start to chop away the frequencies, you’re going to lose amplitude (you’ll need to keep cranking the volume up). The highest frequencies are dead giveaways and low thuds will blow your cover. In the end, I guess, so long as you can’t hear it but you can see movement in your VU meters, you’ve cracked it.
PS. Isn’t there an easier way to bury the key words?
Is it really frequency that you want to mess with? Low enough and your speakers will not reproduce it, and high enough and the system as a whole won’t reproduce it, since anything about 20K Hz is simply chopped off in digital recording. Aren’t subliminal things usually just buried way down in the mix without messing with the frequency of it? Anyway, if you really want to mess with frequency, you can use a pitch alternation plug in to move the frequency up or down. But I still don’t think that that’s what you want.
I would investigate mixing the message with white noise. This way the message is masked by the white noise, but the information is still in the mix.
Google white noise to see if there is a sample that you can use.
rpx, is there any actual scientific evidence for the efficacy of this sort of thing?

depends upon how susceptible you are to the cocktail party syndrome;-)
I’m sorry, did you say something, Tony? I was distracted for a moment there. 
doubtless, distracted , by the sound of an unfurling chocolate wrapper across a crowded room, perhaps?

Am I missing the point here? Are we suggesting that our ears can hear frequencies outside of what is considered to be the normal hearing range, but our brain filters those "unwanted" frequencies out?
Otherwise how is the subliminal effect going to be transmitted to the brain?

Pardon?

It's all very subjective - isn't it? - and a good one. As TomS said, the standard methods included volume sublimity, and the images were/are microscopically brief.

Sadly, it was not a chocolate wrapper. Chocolate is a forbidden sin for me.

"Microscopically brief" describes my motivation to work today, quite nicely.

Heard what?
the key word
Well, I dunno, is there any convincing (tony eat some chocolate) evidence that subliminal tricks like that actually (tony eat some chocolate) work? I’m still waiting for (tony eat some chocolate) our original poster to chime in.
