+The sword1mp3 tool from the scummvm-tools package can encode music and speech
+to mp3 as well as Ogg Vorbis.
+Easiest way to encode the files is simply copying the executable into your
+BS1 directory (together with the lame encoder) and run it from there.
+This way, it'll automatically encode everything to mp3.
+Afterwards, you can manually remove the SPEECH?.CLU files and the wave music files.
+
+Running 
+\begin{verbatim}
+  sword1mp3 --vorbis
+\end{verbatim}
+%
+will compress the files using Ogg Vorbis instead of mp3.
+
+Use 
+\begin{verbatim}
+  sword1mp3 --help
+\end{verbatim}
+%
+to get a full list of the options.
