The Platform Manager, seen below, allows you to define the platforms for your game. A platform consists of a platform name and a base SDK. You can specify as many platforms as desired for any listed SDK.
Wwise includes a list of base platforms which cover the primary SDKs used with Wwise, and you are free to create your platforms according to all the base platforms pertinent to your project. But, additionally, you may wish to add multiple platforms with the same base platform in order to accommodate differences.
For example, you may have both iPhone and iPad platforms to develop in your project. They are not exactly the same even though they are fundamentally iOS platforms. To facilitate your management of these distinct project types, you could create two iOS-based platforms: one specific to iPad and another specific to iPhone.
