ARKit -如何实现SCNRenderer().audioListener？

import ARKit
import SceneKit
import AVFoundation

// 创建SCNRenderer对象
let renderer = SCNRenderer(device: MTLCreateSystemDefaultDevice(), options: nil)

// 创建音频监听器节点
let audioListenerNode = SCNNode()

// 将音频监听器节点添加到场景中
scene.rootNode.addChildNode(audioListenerNode)

// 创建AVAudioEngine对象
let audioEngine = AVAudioEngine()

// 创建AVAudioInputNode对象
let audioInputNode = audioEngine.inputNode

// 连接AVAudioInputNode到音频监听器节点
let audioFormat = audioInputNode.inputFormat(forBus: 0)
audioEngine.connect(audioInputNode, to: audioListenerNode, format: audioFormat)

// 更新音频监听器节点的位置和方向
renderer.update(atTime: 0, viewport: CGRect.zero, commandBuffer: nil, passDescriptor: nil)
