This file contains code from version 1.1 and 1.4 of MyOpenALSupport.h taken from Apple's oalTouch version. |
|||
The 1.4 version code is used for loading IMA4 files, however, this code causes very noticeable clicking |
|||
when used to load wave files that are looped so the 1.1 version code is used specifically for loading |
|||
wav files. |
