Amazing Audio Engine音频引擎

Amazing Audio Engine 是基于 Core Audio 的远程 IO 系统用以提供低延迟的音频连接，通过内置的混音、过滤和生效。该框架支持大多数音频格式和比特率，同时提供音频输入、录制和监控功能。

示例代码：

// Create an instance of the audio controller
self.audioController = [[[AEAudioController alloc]
                         initWithAudioDescription:
                           [AEAudioController nonInterleaved16BitStereoAudioDescription]] 
                         autorelease];
 
AEBlockChannel *channel = [AEBlockChannel channelWithBlock:
  ^(const AudioTimeStamp  *time,
    UInt32           frames,
    AudioBufferList *audio) {
 
    // Generate audio here
 
}];
 
// Add and start playing channel
[_audioController addChannels:[NSArray arrayWithObjects:channel, nil]];
 
// Start the audio engine.
[_audioController start:NULL];
