\subsection{Using compressed audiofiles (MP3, Ogg Vorbis, Flac)}
|
|
|
|
\subsubsection{Using MP3 files for CD audio}
|
|
|
|
Use LAME or some other mp3 encoder to rip the cd audio tracks to files. Name
|
|
the files track1.mp3 track2.mp3 etc. ScummVM must be compiled with MAD support
|
|
to use this option. You'll need to rip the file from the CD as a WAV file,
|
|
then encode the MP3 files in constant bit rate. This can be done with the
|
|
following LAME command line:
|
|
\begin{verbatim}
|
|
lame -t -q 0 -b 96 track1.wav track1.mp3
|
|
\end{verbatim}
|
|
|
|
|
|
\subsubsection{Using Ogg Vorbis files for CD audio}
|
|
|
|
Use oggenc or some other vorbis encoder to encode the audio tracks to files.
|
|
Name the files track1.ogg track2.ogg etc. ScummVM must be compiled with vorbis
|
|
support to use this option. You'll need to rip the files from the CD as a WAV
|
|
file, then encode the vorbis files. This can be done with the following oggenc
|
|
command line with the value after q specifying the desired quality from 0 to 10:
|
|
\begin{verbatim}
|
|
oggenc -q 5 track1.wav
|
|
\end{verbatim}
|
|
|
|
|
|
\subsubsection{Using Flac files for CD audio}
|
|
Use flac or some other flac encoder to encode the audio tracks to files.
|
|
Name the files track1.flac track2.flac etc. In your filesystem only allows
|
|
three letter extensions, name the files track1.fla track2.fla etc.
|
|
ScummVM must be compiled with flac support to use this option. You'll need to
|
|
rip the files from the CD as a WAV file, then encode the flac files. This can
|
|
be done with the following flac command line:
|
|
\begin{verbatim}
|
|
flac --best track1.wav
|
|
\end{verbatim}
|
|
%
|
|
Remember that the quality is always the same, varying encoder options will only
|
|
affect the encoding time and resulting filesize.
|
|
|
|
|
|
\subsubsection{Compressing MONSTER.SOU with MP3}
|
|
|
|
You need LAME, and our extract util from the scummvm-tools package to perform
|
|
this task, and ScummVM must be compiled with MAD support.
|
|
\begin{verbatim}
|
|
extract monster.sou
|
|
\end{verbatim}
|
|
%
|
|
Eventually you will have a much smaller monster.so3 file, copy this file
|
|
to your game directory. You can safely remove the monster.sou file.
|
|
|
|
|
|
\subsubsection{Compressing MONSTER.SOU with Ogg Vorbis}
|
|
|
|
As above, but ScummVM must be compiled with OGG support. Run:
|
|
\begin{verbatim}
|
|
extract --vorbis monster.sou
|
|
\end{verbatim}
|
|
%
|
|
This should produce a smaller monster.sog file, which you should copy to your
|
|
game directory. Ogg encoding may take a considerable longer amount of time
|
|
than MP3, so have a good book handy.
|
|
|
|
|
|
\subsubsection{Compressing MONSTER.SOU with Flac}
|
|
|
|
As above, but ScummVM must be compiled with Flac support. Run:
|
|
\begin{verbatim}
|
|
extract --flac --best -b 1152 monster.sou
|
|
\end{verbatim}
|
|
%
|
|
This should produce a smaller monster.sof file, which you should copy to your
|
|
game directory. Remember that the quality is always the same, varying encoder
|
|
options will only affect the encoding time and resulting filesize. Playing
|
|
with the blocksize (-b <value>), has the biggest impact on the resulting
|
|
filesize -- 1152 seems to be a good value for those kind of soundfiles. Be sure
|
|
to read the encoder documentation before you use other values.
|

\subsubsection{Compressing sfx/speech in Simon the Sorcerer 1 and 2}
|
|
|
|
Use our simon2mp3 util from the scummvm-tools package to perform this task.
|
|
You can choose between multiple target formats, but note that you can only use
|
|
each if ScummVM was compiled with the respective decoder support enabled.
|
|
|
|
\begin{tabular}[h]{ll}
|
|
simon2mp3 effects &(For simon1acorn)\\
|
|
simon2mp3 simon &(For simon1acorn)\\
|
|
simon2mp3 effects.voc&(For simon1talkie)\\
|
|
simon2mp3 simon.voc &(For simon1talkie)\\
|
|
simon2mp3 simon.wav &(For simon1win)\\
|
|
simon2mp3 simon2.voc &(For simon2talkie)\\
|
|
simon2mp3 simon2.wav &(For simon2win)\\
|
|
simon2mp3 mac &(For simon2mac)\\
|
|
\end{tabular}
|
|
|
|
For Ogg Vorbis add --vorbis to the options, i.e.
|
|
\begin{verbatim}
|
|
simon2mp3 --vorbis
|
|
\end{verbatim}
|
|
%
|
|
For Flac add --flac and optional parameters, i.e.
|
|
\begin{verbatim}
|
|
simon2mp3 --flac --best -b 1152
|
|
\end{verbatim}
|
|
%
|
|
Eventually you will have a much smaller *.mp3, *.ogg or *.fla file, copy this
|
|
file to your game dir. You can safely remove the old file.
