Alexander Hodge just published his Game Audio Harmonization Tutorial.
This tutorial will guide you through the process of using AudioKit within a Unity iOS project to create procedural sound effects that are harmonized with the game music. The tutorial expects a basic level of familiarity with Unity and its game development environment, as well as Apple’s Xcode IDE and Objective-C. The tutorial uses Unity 5.0.0.f4, available at http://www.unity3d.com, Xcode 6.2 available at https://developer.apple.com/xcode/downloads/), and AudioKit 2.0 available at http://www.audiokit.io. AudioKit is an open source iOS library for audio synthesis, processing, and analysis. The tutorial also uses Veemix, an integrated game music platform (https://www.veemix.com) and EchoNest (http://the.echonest.com) for music information retrieval.
