	You need double the sampling rate as the highest frequency in the sound.	This stems from the Nyquist-Shannon sampling theorem.
	Digital-to-Analog Conversion, the process of returning to an analog signal.	Great job!
	We can reasonably expect no human can hear frequencies above 22,050 Hz.	This doesn't answer the question.
	Analog-to-Digital Conversion, the process of going from an analog signal to a digital signal.	The other way around.
