I am looking to use the cross correlation function to find the delay between two
signals.. I am a bit confused by the output of the function.. The vdsp manual says
"The signals to be correlated are given by the input vectors samples_x
and samples_y. The length of the input vectors is given by
sample_length. The functions return the result in the array correlation
with lags elements."
What is the correlation array and lags elements? I thought it would just return a shift
size to the maximum correlation between the two signals in samples_x and samples_y?
Any help would be great,
