====== reogg - Prepare audio-files for radio loops ======

Did you ever want to automate live audio streaming from the command-line? Well, I do. To cut it short the requirements here were:
  * command-line (terminal) only
  * generate one long stream - concatenate all songs
  * retain (id3) tags
  * stream [[wp>Ogg/Vorbis]] to an [[http://icecast.org|icecast]] server
  
In principle one can simply concatenate OGG files and use [[http://v2v.cc/~j/oggfwd/|oggfwd]] to send it to icecast. However most players (in particular mplayer) will produce garbled output when mixing OGG files with different bitrate/samplerate/channels in one stream. Furthermore some input files may not be OGG/Vorbis encoded in the first place.

To remedy the situation, here's a simple shell-script that converts all files in a given folder to a common format and copies over the id3 tags. You'll need to have ''oggenc'', ''oggdec'', ''mpg321'', ''flac123'' and ''id3tool'' installed.

You can [[http://gareus.org/gitweb/?p=scripts.git;a=blob_plain;f=reogg.sh|download the script from the repository]], but it's simple enough to be printed here:
<code|h view reogg.sh source>
extern>http://gareus.org/gitweb/?p=scripts.git;a=blob_plain;f=reogg.sh;hb=HEAD
</code>
\\

To transmit the converted files repeatedly to an icecast server I run the following shell script in a [[wp>Gnu_Screen|GNU Screen]]:
<code|h view loop_ice.sh source>
extern>http://gareus.org/gitweb/?p=scripts.git;a=blob_plain;f=loop_ice.sh;hb=HEAD
</code>

If you find these scripts useful or want to suggest some improvements.. drop me a word:
