Audio Support

Sid Meier's Civilization Revolution

Scaleform® GFx™ 3.0 provides full support for audio embedded in Adobe® Flash® SWF files. All embedded sounds in SWF and GFX files play directly from Scaleform GFx 3.0 using any sound engine implementing the Scaleform GFx 3.0 C++ sound renderer interface. Sound from Scaleform Video will also be played via the new sound renderer.

Scaleform GFx 3.0 allows you to easily play sounds embedded inside a Flash file using the sound engine of your choice. We provide a default implementation of our renderer interface with the widely used, cross-platform FMOD™ sound library. Scaleform GFx 3.0 audio support handles both event and streaming sounds.
