Windows phone 8 play sound according to bit array

I have a textbox in my app, and for example it contains: "Hello World!". I have a wav file that represents a beep(1 ms). In accordance to the "Hello World" bits representation I want to play the beeps in this manner: play beep if '1' or wait for 1 ms(silence). What is the best way to achive this? Thanks.
