SDL2_mixer is a sample multi-channel audio mixer library. It supports any number of simultaneously playing channels of 16-bit stereo audio, plus a single channel of music. It is safe to install alongside Slackware's SDL libraries. Optional dependencies are: * libmodplug (for MOD support) * fluidsynth or TiMidity++ (for MIDI suport) * smpeg2 (for MP3 support, not available on SBo)
