audio, plus a single channel of music. Supported formats include FLAC, MOD,
MIDI, Ogg Vorbis, and MP3.
This package supports two MIDI backends, selectable at runtime. To use the
newer @code{fluidsynth} library, install a soundfont such as @code{fluid-3}
and specify it using the @code{SDL_SOUNDFONTS} environment variable. For the
legacy @code{timidity} backend, install a patch set such as @code{freepats}
and set the path to the configuration file with @code{TIMIDITY_CFG}.")
