This module computes the most usual cross-functions between channel left and right: autocorrelations, cross correlation, impulse responses h1, h2 and h3.
The result can be optionally Hilbert-transformed, for showing the magnitude envelope. During the processing a "following filter" can be applied to the signal, tracking the peak frequency of one of the two channels. This can be very useful for improving the S/N ratio in measurements conducted with the sine sweep method.
This is the user's interface of the Cross-functions module:
