Cocos2d-x 3.4 in its experimental phase had a new audio engine built from scratch in order to add more functionalities and flexibility. The new audio engine of Cocos2d-x is now available for the Android, iOS, the Mac OS, and the win-32 platforms. It is able to reproduce up to 24 simultaneous sounds on the Android platform; this number may change depending on the platform.
