+	<name>DC shift</name>
+	<description>Apply a DC shift to the audio.
+This can be useful to remove a DC offset (caused perhaps by a hardware problem in the recording chain) from the audio.
+The effect of a DC offset is reduced headroom and hence volume. The astats filter can be used to determine if a signal has a DC offset.</description>
