AudioKit是一个开源的强大的音频合成、处理和分析库。用于iPhone/OSX应用的开发，支持Objective-C和Swift语言。
示例代码：
#import "NewInstrument.h"@implementation NewInstrument- (instancetype)init{ self = [super init]; if (self) { AKSineTable *sineTable = [[AKSineTable alloc] init]; [self addFTable:sineTable]; AKFMOscillator *fmOscillator; fmOscillator = [[AKFMOscillator alloc] initWithFTable:sineTable baseFrequency:akp(440) carrierMultiplier:akp(1) modulatingMultiplier:akp(0.5) modulationIndex:akp(1.0) amplitude:akp(0.1)]; [self connect:fmOscillator]; AKAudioOutput *audioOutput = [[AKAudioOutput alloc] initWithAudioSource:fmOscil]; [self connect:audioOutput]; } return self;}@end
