Once you get the text you want to make into a subliminal, it's really very easy. First you need a cover noise. You can generate white noise in Audacity, which sounds like static, use some free loopable sounds from online like the sound of a waterfall or running water (just make sure the sound is not copyrighted if you plan to distribute the completed file,) or even-- if you plan to use the file for yourself only-- use music as your cover sound. Then you just import both tracks into Audacity, repeat the cover sound enough times to last the length of the speech track, then adjust the relative volumes so that the speech track is barely audible under the cover sound. It's very, very simple.
