A Stereo signal system creates an impression such that the listner imagines the source to be moving from left to right.This effect is called Panning .Write a program to take a mono audio input and create the Panning Effect



cud any one help in some C code for the above mentiooned prob

or any kind of c code related to the above prob

any kind of related is helpful
 

please use two channel for same data so you can make it in stereo mode.

then use one function who continuously change its weight in complementry order according to moving speed i.e.

x = original signal
x1 =x;
x2 =x;
g = gain factor;
g1 = g/2;
g2 = g/2;
for i =1:1:100
j = 100-i
y1 = g1*y1/i;
y2 = g2*y2/j;
end

then merge this two signal by interleaving them or play it in stereao mode.
