Remarks
Loads a specific audio channel from a sound in RAW format contained inside a memory buffer.
You can manage how loaded sound will be added to the existing editing session through a previous call to the SetLoadingMode method.
You can limit the range of sound data that will be loaded from the given sound file with a previous call to the SetLoadingRange method.
A successful call to this method will fire the SoundLoadingStarted event followed by a number of SoundLoadingPerc events and finally by the SoundLoadingDone event.
IMPORTANT TOPIC: remember that the memory buffer containing song data must not be moved by the garbage collector and needs to be available till the call to the CloseSound method.
