The idea behind this feature request is well explained under te topic
"Cross-Correlation" on this paper:
  http://www.rs-met.com/documents/tutorials/StereoProcessing.pdf

In order to achieve what's explained there, one can use the spectrum plugin,
but as it is, is merges all channels into a single(mono) one.

The solution right now, is to deinterleave to get both monos out of a stereo
signal, pass each to the spectrum plugin and do the explained calculations
using both mono sources to achieve the goal proposed on this enhancement
request.
