Virtual Sources in Front of the Array

In all cases considered so far, the virtual sources (primary sources) have been restricted to be behind the speaker array by some minimum distance for valid sampling. We can now extend as in WFS to allow sources between the array and the listener, but we still must maintain the same minimum distance, but now from the other side of the array. There are differences, however, to keep in mind relative to the behind-the-array case. For simplicity, consider a line or plane array as a starting point.
