I run the following code
f=wavread('tes.wav','native'); v=[1/sqrt(2) 1/sqrt(2)]; w=[1/sqrt(2) -1/sqrt(2)]; if mod(length(f),2)~=0 f=[f 0]; end d=length(f); m=1:d/2; a1=f(2*m-1).*v(1) + f(2*m).*v(2); d1=f(2*m-1).*w(1) + f(2*m).*w(2);
But something seems not right to me, the result:
the raw signal was = < 250608x2 int16 > but after i process it become like a1 < 1x125304 int16 > and d1 < 1x125304 int16 >, what i expected is like a1 < 125304x1 int16 > ? do you know how i can achieve this?
Why is that change from 250608x2 become 1x125304 anyway. m x n, m = number of sample and n=number of chanel right? why does it's exchange position?
