Amazing Audio Engine音頻引擎

Amazing Audio Engine 是基于 Core Audio 的遠(yuǎn)程 IO 系統(tǒng)用以提供低延遲的音頻連接，通過(guò)內(nèi)置的混音、過(guò)濾和生效。該框架支持大多數(shù)音頻格式和比特率，同時(shí)提供音頻輸入、錄制和監(jiān)控功能。

示例代碼：

// 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];
