+<para>
+This audio filter exports the incoming signal to other processes using memory
+mapping (<literal>mmap()</literal>). Memory mapped areas contain a header:
+
+<programlisting>
+int nch                      /*number of channels*/
+int size		     /*buffer size*/
+unsigned long long counter   /*Used to keep sync, it's updated
+                               every time new data is exported.*/
+</programlisting>
+
+The rest is payload (non-interleaved) 16bit data.
