I want to change voice of file as quick as posibly. I used follow code:

result = system-\>playSound(sound, 0, 0, &channel);  
ERRCHECK(result);  
//Spped 10 times  
float frequency;  
channel-\>getFrequency(&frequency);  
frequency = frequency \* 60;  
channel-\>setFrequency(frequency);

But it seems doesn’t work. Could you give me some advice? I really need it to develop a tool for file voice changing.

Thanks.
