Audio Support

Autodesk Scaleform provides full support for audio embedded in Adobe® Flash® SWF files. All embedded sounds play directly from Scaleform using any sound engine implementing the Scaleform C++ sound renderer interface. Sounds can also be easily played using the ActionScript 3 Sound class.

Autodesk Scaleform 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. (Please contact FMOD sales for licensing terms and conditions.) Autodesk Scaleform audio support handles both event and streaming sounds.

All methods of embedding and playing sounds inside a Flash® SWF file are supported by the sound renderer interface. Sounds from video playback will also be played via the sound renderer. You are free to plug your own sound library into Autodesk Scaleform using the sound renderer interface. Please verify the licensing terms of the sound library packaged with the end product
