32 bit audio is higher resolution, it can have effects applied to it in higher detail. like subpixel coordinates might more clearly specify a pixels colours... anything beyond 16bit (which is streamed to your speakers) is not audible though in the sense of playing it to the speaker. it matters in processing (dsp).
