RealSound

From Wikipedia, the free encyclopedia

RealSound is a patented technology for the PC created by Access Software during the late 1980s. RealSound enables digitized PCM-audio playback on the PC speaker. The first video game to use it is World Class Leader Board which was released in 1988. At the time of release, sound cards were very expensive and RealSound allowed people to get life-like sounds and speech with no additional sound hardware, just the standard PC speaker.

Examples of games using RealSound:

  • Legend Entertainment:
    • Spellcasting 101

RealSound was a good technology but as soundcards got cheaper, Access Software stopped supporting it. Nevertheless, it inspired other PC video game developers like Legend Entertainment, who liked the idea of digitized-audio on the PC-speaker. This feature found its way into a decent number of PC games up until the early 1990s, when add-in sound cards began a baseline requirement for gaming PC-audio.
