<H2><A NAME="s12">12. Listening to MP3's.</A></H2>
<P>So, hopefully, you should now have some MP3 files ready to listen to, and have the choice of playing from file or stream.
<P>
<H2><A NAME="ss12.1">12.1 Playing from File</A>
</H2>
<P>
<P>Playing from file is reasonably straight-forward with all players. The only big difference is some are command-line based and some are X based.
<P>Playing an MP3 file from file requires you to pass the mp3 file as a parameter, like so:
<P>
<HR>
<PRE>
[dj@megajukebox]$ mpg123 /mp3_files/SampleFile.mp3
or
[dj@megajukebox]$ xaudio /mp3_files/SampleFile.mp3
</PRE>
<HR>
<P>If you want to play a series of files, pass them in as a list:
<P>
<HR>
<PRE>
[dj@megajukebox]$ alsaplayer /mp3_files/SampleFile1.mp3 /mp3_files/SampleFile2.mp3
</PRE>
<HR>
<P>To play all the tracks in a directory, just wildcard the file selected, like so:
<P>
<HR>
<PRE>
[dj@megajukebox]$ xmms /mp3_files/*.mp3
</PRE>
<HR>
<P>
<H2><A NAME="ss12.2">12.2 Playing from MP3 Streams</A>
</H2>
<P>
<P>Playing from a MP3 stream is quite easy, just replace the file with the streams url and port number:
<P>
<HR>
<PRE>
[dj@megajukebox]$ mpg123 http://localhost:8000
or
[dj@megajukebox]$ freeamp http://megajukebox:2711
</PRE>
<HR>
<P>
<H2><A NAME="ss12.3">12.3 Capturing MP3 Streams</A>
</H2>
<P>A stream from a MP3 server can be captured and save locally using the following:
<P>
<H3>Streamripper</H3>
<P>
<P>To capture an MP3 stream using streamripper, type the following:
<P>
<HR>
<PRE>
[dj@megajukebox]$ streamripper -h megajukebox -p 8000
Press CTRL-C to stop

<P>eMixer gives you the ability to mix MP3's in a similar manner to a DJ's mixing desk.
