使用蓝牙设备在AVCaptureSession中录制音频

import AVFoundation

func setupAudioCapture() {
    let session = AVCaptureSession()
    
    // 获取所有音频输入设备
    let audioDevices = AVCaptureDevice.devices(for: .audio)
    
    // 遍历设备，找到蓝牙设备
    for device in audioDevices {
        if device.position == .builtInMic {
            // 设置蓝牙设备为音频输入
            let audioInput = try? AVCaptureDeviceInput(device: device)
            if session.canAddInput(audioInput!) {
                session.addInput(audioInput!)
            }
        }
    }
    
    // 设置音频输出
    let audioOutput = AVCaptureAudioDataOutput()
    if session.canAddOutput(audioOutput) {
        session.addOutput(audioOutput)
    }
    
    // 开始捕捉音频数据
    session.startRunning()
}
