A format conversion provider provides format conversion services
from one or more input formats to one or more output formats.
Converters include codecs, which encode and/or decode audio data,
as well as transcoders, etc. Format converters provide methods for
determining what conversions are supported and for obtaining an audio
stream from which converted data can be read.
The source format represents the format of the incoming
audio data, which will be converted.
The target format represents the format of the processed, converted
audio data. This is the format of the data that can be read from
the stream returned by one of the getAudioInputStream
methods.
