+  <para>
+    The polarity of a track can be inverted in the Mixer Window by clicking
+    on the track name button of a Mixer Strip and choosing

+    When the polarity of a track is inverted a <literal>Ø</literal> will
+    appear before the track name in the Mixer Strip.

+  <para>
+    This could be used to correct the polarity of an input signal due to
+    incorrect wiring or to prevent two signals that are out of phase with
+    respect to each other resulting in cancellation when mixing.

-      The polarity button, when pressed, inverts the phase of the signal as
-      it leaves the track and enters the mixer strip. it has no effect on
-      the signal being recorded to disk. It has no effect on the timing of
-      the signal, either.
