// SAASound.h: interface for the CSAASound class.
|
|
//
|
|
// This corresponds to the public (exported) DLL interface, so all
|
|
// APIs and client factory methods belong here.
|
|
//
|
|
// Compatibility notes : the intention is for this to be fully backwards
|
|
// compatible across minor and patch versions. Any backwards breaking changes
|
|
// should be reflected as a major version increment. New functionality can be added
|
|
// in minor versions so long as backwards compatiblity is maintained
|
|
//
|
|
// Version 3.3.0 (4th Dec 2018)
|
|
