+                will decreased to 0 and will die. The only solution is to use own reference to our implementation.
+                But we do it for really started jobs only and release it during call back of vcl.

+                If it is - we return right internal type name - otherwise we return nothing!
+                So call can search for another detect service and ask him too.
+
+    @attention  a) We don't need any mutex here ... because we don't use any member!
+                b) Don't use internal player instance "m_pPlayer" to detect given sound file!
+                   It's not necessary to do that ... and we can use temp. variable to do the same.
+                   This way is easy - we don't must synchronize it with currently played sounds!
+                   Another reason to do so ... We are a listener on our internal ma_Player object.
+                   If you would call "IsSoundFile()" on this instance, he would call us back and
