First step : start with something alot simpler than an FFT.

You should solve it in the following order.
1. Be familiar with your board and audio CODEC. 2. Write or get a module to drive the audio CODEC. Use it and understand it. 2. Choose between a pure hardware solution or a Nios II based solution. 3. If you have choosen a pure hardware solution there is a lot of stuff to study about fft implementation: Altera core, own core, open core. 4. If you have choosen a Nios II based solution you must connect your audio CODEC module as an slave peripheral. Internet is full of C language based FFT implementations.- Mark as New

You could try looking this two tutorials,
http://www.altera.com/literature/tt/tt_nios2_hardware_tutorial.pdf (http://www.altera.com/literature/tt/tt_nios2_hardware_tutorial.pdf) http://www.nioswiki.com/@api/deki/files/7/=my_first_nios2_software_tutorial_v72.pdf (http://www.nioswiki.com/@api/deki/files/7/=my_first_nios2_software_tutorial_v72.pdf) Nevertheless, here http://www.altera.com/literature/lit-nio2.jsp (http://www.altera.com/literature/lit-nio2.jsp) you will find all Nios II Stuff.- Mark as New

Why not use what's already on Terasic's website?
http://www.terasic.com.tw/cgi-bin/page/archive.pl?language=english&no=83 There are two audio examples near the bottom of this page. Cheers, - Brendan- Mark as New

You could use example module included in example suggested by Brendan, another option is the Altera University Program cores:
