音頻合成、處理和分析平臺：AudioKit
AudioKit 是一個開源的強大的音頻合成、處理和分析平臺，沒有陡峭的學習曲線。用于 iPhone/OS X 應用的開發，支持 Objective-C 和 Swift 語言。
100+ Synthesizers and FX
物理模型，光譜效應，顆粒合成，效果處理，過濾器，混響等。
Built-in Sampler
錄制音頻流，包括從麥克風。可重新錄制和快速處理。
Powerful Sequencing
Sequences are not limited to the usual notes-on-a-score, but can contain blocks of any code that can be triggered at any time.
Full-featured Examples
The list of examples is growing, but already contains projects demonstrating audio techniques such as FM Synthesis, Granular Synthesis, Convolution, Effects Processing, and Pitch-Shifting, and more.
Simple, Human-readable Code
Coding with audio with audio metaphors - Conductors control Orchestras, which contain Instruments that produce Notes. Clear methods with Apple-style naming conventions, Xcode completion, documentation and tool-tips.
Write your audio-code along side your app logic
The same code that controls your data and user interface controls your sound in Objective-C or Swift.
