Working on Silent Subliminal Messages

I guess maybe I should be asking about the alternative as well. Let’s say we get nowhere with ultra low frequencies, how do I change the frequency of the audio file to be just above human range of hearing? Say, above 20khz. Normal speech speed, but higher in frequency; dog range of hearing, but just outside of human. Thanks!
