I am a newbie to audio technology, you might have answer to my queries below.

I have one tone(wav file) audio application  settings is 44.1khz sampling rate with 16 bit rate...

how can I make my tone to play at 20khz frequency that is not audible to human.

Is there any formula? or conversion algorithm?

anyone have a precise explanation on this differences? it might help me learn faster on this.

are you trying to generate a tone, or pitch shift an existing signal?
