+	purpose = decode or process audio data from STDIN to STDOUT
+	[description]
+		This program allows to specify a chain of filters which transform the
+		audio stream read from STDIN. A common mode of operation is to decode
+		an mp3 file with the mp3dec filter, but many other filters exist which
+		transform the audio stream in different ways.

+			A filter specifier begins with the name of a supported filter,
+			optionally followed by zero or more options for the named filter.
+			Filter name and options must be separated by whitespace. If the
+			there is at least one option, the filter specifier needs to be quoted
+			like this:
+
+				--filter 'compress --inertia 5 --damp 2'
+
+			This option may be specified multiple times to 'pipe' the stream
+			through all given filters (in a single thread without copying the
+			data). The same filter may appear more than once, and order matters.
