I am working on a program using the Essentia library for audio analysis. I've implemented the Cross Correlation algorithm (here: http://essentia.upf.edu/documentation/reference/std_CrossCorrelation.html), but I'm not sure if I really understand the output. Sadly, barely any of the description on that page makes sense to me. I do not have a math background, and only a cursory understanding of frequency analysis / signal processing.
So... can anyone explain what the optional parameters (minLag, maxLag) do here?
