First post, sorry if I'm doing something wrong.



I recently got a ADAU1761 eval board.


I want to take an input signal, and play it back at half or twice speed.  I basically want a frequency halver / doubler. So a 220Hz sound wave in sounds like a 110 or 440 Hz out.


Is this possible?  I'm brand new to DSP.


Thank you
