===Audio conversion from light patterns=== The stroboscopic effect also plays a role in audio playback. [[Compact disc]]s rely on strobing reflections of the laser from the surface of the disc in order to be processed (it is also [[CD-ROM|used for computer data]]). [[DVD]]s and [[Blu-ray Disc]]s have similar functions. The stroboscopic effect also plays a role for [[laser microphone]]s.
