You can add options in the "Audio" setting multi-band equalizer with presets to make it sound a little better, "lively" or, for example, in order to enhance the bass and percussion instruments more clearly heard, and thus a better feel the rhythm. Also, as an experiment you can try to build in the game DSP manager. The idea of built-in equalizer took out LunaticRave2, but about the very thought of a preset.
