iPhone音频均衡器

iPhone音频均衡器,iphone,ios,objective-c,avplayer,Iphone,Ios,Objective C,Avplayer,我正在使用AVPlayerLayer播放网络视频: AVAsset *newAsset = [[AVURLAsset alloc]initWithURL:url options:nil]; AVPlayerItem *newPlayerItem = [[AVPlayerItem alloc]initWithAsset:newAsset]; audioPlayer = [[AVPlayer alloc]initWithPlayerItem:newPlayerItem]; avPlayerLay

我正在使用
AVPlayerLayer
播放网络视频:

AVAsset *newAsset = [[AVURLAsset alloc]initWithURL:url options:nil];
AVPlayerItem *newPlayerItem = [[AVPlayerItem alloc]initWithAsset:newAsset];

audioPlayer = [[AVPlayer alloc]initWithPlayerItem:newPlayerItem];

avPlayerLayer = [AVPlayerLayer playerLayerWithPlayer:audioPlayer];
我希望能够将
音频均衡器添加到视频中。比如:

Pop, Flat, Balled, Blues, Classical, Dance, Metal
我在谷歌和苹果开发者计划资源中搜索了这方面的信息和文档,但什么也没找到。 我还注意到有些应用程序有这个功能,但它只适用于iOS 6.1


在这个问题上有什么帮助吗?苹果有内置的还是非苹果源?

这个堆栈溢出问题的答案提供了几种不同的解决方案:
