以下是一个示例代码，演示了如何使用AVAudioEngine、AVAudioPlayerNode和AVAudioPCMBuffer在Swift中创建一个基本音频播放器，并安排一个包含噪声的缓冲区：

import AVFoundation

// Create the audio engine
let engine = AVAudioEngine()

// Create the player node
let player = AVAudioPlayerNode()
engine.attach(player)

// Create the audio file buffer
let fileURL = Bundle.main.url(forResource: "audioFile", withExtension: "wav")!
let audioFile = try! AVAudioFile(forReading: fileURL)
let audioFormat = audioFile.processingFormat
let audioFrameCount = UInt32(audioFile.length)
let audioFileBuffer = AVAudioPCMBuffer(pcmFormat: audioFormat, frameCapacity: audioFrameCount)!
try! audioFile.read(into: audioFileBuffer)

// Create a glitchy noise buffer
let glitchyBuffer = AVAudioPCMBuffer(pcmFormat: audioFormat, frameCapacity: audioFrameCount)!
let noiseGenerator = NoiseGenerator(amplitude: 0.5, sampleRate: Double(audioFormat.sampleRate))
for frame in 0..
