AudioKit音頻合成、處理和分析庫

AudioKit 是一個(gè)開源的強(qiáng)大的音頻合成、處理和分析庫。用于 iPhone/OS X 應(yīng)用的開發(fā)，支持 Objective-C 和 Swift 語言。

示例代碼：

#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;
}
