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];
