AudioKit is a powerful audio toolkit for synthesizing, processing, and analyzing sounds. It contains several examples for iOS (iPhone & iPad) and Mac OSX, written in both Objective-C and in Swift. A test suite is provided for many of the operations included in AudioKit. A playground project can be used for trying out AudioKit instruments and for greatly speeding up the development of your own instruments and applications.
The "AudioKit" subfolder
This folder contains the classes that you will need to copy or reference in your project by dragging this folder into Xcode. In addition to the audio classes, there is a Utilities folder that contains non-required, but helpful classes for binding user-interface elements to audio data, including plots of audio streams and related data.
This folder contains information about automatically generating Xcode documentation from the AudioKit source.
For most users, the documentation you really want: installation instructions, tutorials, examples, and more can be found here: http://audiokit.io/
Included with AudioKit are two examples (HelloWorld and AudioKitDemo) written in two languages (Objective-C and Swift) for two operating systems (iOS and OSX). So, there are eight projects for each permutation. The Hello World project is a great starting point and a walkthrough is available here. In Hello World, only one file is used to create a sine oscillator playing at 440Hz. The AudioKitDemo is quite a big more complex, combining three apps into one to demostrate audio synthesis, processing, and analysis techniques.
Here is where the main AudioKitPlayground project is kept and from here you can run a shell script to start the playground from a set of template playgrounds. Refer to the README within this folder for more instructions.
We have built Xcode templates for typical AudioKit classes: instrument, processor, and conductor. Once installed, these templates will be available from within Xcode's new file wizard.
Numerous tests can be run utilizing the AudioKitTest project and the
run.sh shell scripts provided here.
