+#X text 288 427 Now take the FT of the forward window and multiply
+it by the unit complex number from above. The magnitude will be that
+of the forward window and the phase will be the previous output phase
+plus the phase difference between the two analysis windows -- except
+that if "lock" is on \, they will be modified to agree progressively
+better with the inter-channel phase relationships of the input.;
+#X text 249 242 If "lock" is on \, encourage neighboring channels to
+stay in phase by adding the two neighboring complex amplitudes. The
+result will tend toward the channel with the strongest amplitude. If
+the phase relationships between channels in the output and those in
+the input are in parallel \, then neighboring channels of the quotient
+will all have the same phase and this will not change any phases. (lrshift
+shifts the signal to the left or right depending on its argument.)
