|
|
// This is the internal implementation (header file) of the SAASound object.
|
|
// This is done so that the external interface to the object always stays the same
|
|
// (SAASound.h) even though the internal object can change
|
|
// .. Meaning future releases don't require relinking everyone elses code against
|
|
// the updated saasound stuff
|
