*para_server*
-para_server streams binary audio data (MP3, OGG/Vorbis, OGG/Speex,
-M4A, WMA files) over local and/or remote networks. It listens on a
-TCP port and accepts commands such as play, stop, pause, next from
-authenticated clients. There are many more commands though, see the
-man page of para_server for a description of all commands.

It supports three built-in network streaming protocols
(senders/receivers): HTTP, DCCP, or UDP. This is explained in more
A command line HTTP/DCCP/UDP stream grabber. The http mode is
compatible with arbitrary HTTP streaming sources (e.g. icecast).
+In addition to the three network streaming modes, para_recv can also
+operate in local (afh) mode. In this mode it writes the content of
+an audio file on the local file system in complete chunks to stdout,
+optionally 'just in time'. This allows to cut an audio file without
+first decoding it, and it enables third-party software which is unaware
+of the particular audio format to send complete frames in real time.
*para_filter*
A small stand-alone program that prints tech info about the given
audio file to STDOUT. It can be instructed to print a "chunk table",
-an array of offsets within the audio file or to write the content of
-the audio file in complete chunks 'just in time'.

or raw audio player.
