Navid,
For all of our licensing, the rules are pretty much the same.
For the crediting, you can find what you need here:
https://www.audiokinetic.com/resources/credits/.
The requirements are your 'best efforts'. For us, that means:
1) Minimally, the text line should appear in your credits, if they exist.
2) If your credits can display images, then our logo should be there too.
3) If you DO have a splash screen or area of a screen that displays technology logos, then ours should be there.
4) If you DO NOT have that already, then you don't need to make one just for us.
Hope that all makes sense!
