如何使用 Swift 使用 TheAmazingAudioEngine 播放音频文件？

Question

我需要使用 TheAmazingAudioEngine framework 和 Swift 播放单个音频文件。 我完全是这个框架的新手，并尝试了下面的代码，但音频没有播放。怎么了？如何播放音频文件？

do {
    var audioController = AEAudioController(audioDescription: AEAudioController.nonInterleavedFloatStereoAudioDescription())
    let file = NSBundle.mainBundle().URLForResource("myaudiofile", withExtension: "wav")!
    let channel = try AEAudioFilePlayer(URL: file)
    audioController?.addChannels([channel])
    channel.playAtTime(0)
} catch {
    print("Failure")
}

我错过了启动audioController：

do {
    var audioController = AEAudioController(audioDescription: AEAudioController.nonInterleavedFloatStereoAudioDescription())
    let file = NSBundle.mainBundle().URLForResource("myaudiofile", withExtension: "wav")!
    let channel = try AEAudioFilePlayer(URL: file)
    audioController?.addChannels([channel])
    try audioController!.start()
} catch {
    print("Failure")
}
