- Any idea about coding a "waveform visualizer" while the music is playing, much like Winamp or WindowsMediaPlayer styles? You know, the wave is draw while the music plays, or some artistic graphics.
A basic oscilliscope view is incredibly easy and requires no real calculations. Just plot a point based directly on the output sample (-32768 = bottom, 0 = center, 32767 = top). I've done them this way in the past and they look fine.
