In ADX2, there are two Pan Types, Pan [5.1]<\/b> and 3D Positioning [3D]<\/b>. Pan [5.1]<\/b> can be considered a 2D pan type, like typical stereo panning, where the level sent to each speaker controls the spatial image. 3D Positioning<\/b> works similarly and additionally allows for dynamic volume control based on the distance between source and listener. <\/p>\n
In general, we might use Pan [5.1] <\/b>for something static like music, perhaps making full use of 5.1, or simply using it to reproduce a balanced \u201cstereo\u201d playback. Conversely, 3D Positioning <\/b>might be used in a 3D game where the character can move around objects which produce a sound. This approach creates a more immersive experience that allows the player to understand the world around them. <\/p>\n
The drawback of both Pan Types is that they assume the player has a 5.1 surround sound system to reproduce the spatial effect. And a consequence of this approach is that, when using headphones, sounds directly left of the player will be hard-panned to the left speaker. Fortunately, ADX2 offers a DSP effect that simulates surround sound listening with headphones. This creates a deeper and more natural listening experience.<\/p>\n
In this blog, we will create a togglable system showcasing the above effect. And since this approach uses Snapshots, it could even be implemented in-game, allowing players to chose the system that best matches their setup. <\/p>\n
