DE2 Karaok Demonstration - Retrieve Sound Data

Honored Contributor I

Hi All, 


I would like to analyze the sound data that i captured from microphone. 

I noticed that on the DE2 Demonstration, there is a Karaok-Machine program. 


I tried to run the program. I found that i can only hear my own voice when i speak very near to the mic.. then it only works at some interval of times. 


May i know, any one here run the program smoothly b4?  



With the purpose to analyze the input sound signal, may i know which variable is indicating the sampled sound data? I tried to go through the code. But I found difficulties to understand it properly and identify which is the sound data... 


Many Thanks.
