How to get beats per minute of music played with wwise?

Question

I music playing when player starts the level, but I need the beats per minute of the song. The songs can be different for the same level, so was wondering if Wwise has a function to get the bpm. Otherwise I feel I am just going to have to know the bpm of each song and hard code it?

Hey Tyler, 

Yes there is a way to get the tempo in the game engine. If you are using Unity, you can get it in your callback function like this: 

void CallbackFunction(object in_cookie, AkCallbackType in_type, object in_info)
{
     AkMusicSyncCallbackInfo info = (AkMusicSyncCallbackInfo)in_info;
     print(60/info.segmentInfo_fBeatDuration);
}

And here is there's more on Music Callbacks.
