A codec can encode and/or decode audio data.  It provides an
AudioInputStream from which processed data may be read.

Its input format represents the format of the incoming
audio data, or the format of the data in the underlying stream.

Its output format represents the format of the processed, outgoing
audio data.  This is the format of the data which may be read from
the filtered stream.
