Slow motion effect for sound
I’m very new to this engine. Actually I’ve interested in it because I need to implement one simple(as I think) thing – it’s slowing down music and sounds when pause menu occurs and accelerate up after it hides.
Something like here – https://vimeo.com/174327353
Is there a simple way achieve this? I tried just to set using default cocos2d-iphone engine pitch linearly, but it work very bad..
How this effect can be done with The Amazing Audio Engine?
