Audio game history

The term "electronic game" is commonly understood as a synonym for the narrower concept of the "video game." This is understandable as both electronic games and video games have developed in parallel and the game market has always had a strong bias toward the visual. The first electronic game, in fact, is often cited to be Cathode-Ray Tube Amusement Device (1947) a decidedly visual game. Despite the difficulties in creating a visual component to early electronic games imposed by crude graphics, small view-screens, and power consumption, video games remained the primary focus of the early electronic game market.

As video games flourished and became increasingly common, however, amateur game designers began to adapt video games for the blind via sound. In time audio game programmers began to develop audio-only games, based to a smaller and smaller degree on existing video game ideas and instead focussing on the possibilities of game immersion and feedback with sound.
Specifically, 3-dimensional positional audio (binaural recording

. To effect this, a sound is played in the left, center, or right channel to indicate an object's position in a virtual gaming environment. Generally, this involves stereo panning of various sound effects, many of which are looped to serve as indicators of hazards or objects with which the user can interact. Volume also plays a major role in 3D audio games primarily to indicate an object's proximity with reference to the user. The pitch of a sound is often varied to convey other information about the object it symbolizes. Voice talent is used to indicate menu items rather than text. These parameters have allowed for the creation of, among other genres, side scrollers, 3D action adventures, shooters, and arcade style games.
