Question

我试图制作一个可以同时快速录制AudioKit AKOscillatorBank和来自麦克风的人声的钢琴声音的应用程序。我尝试了AVFoundation的AVAudioRecorder，但是在弹钢琴时失败了。我尝试使用AVAudioSessionCategoryPlayAndRecord，但它似乎仍然无法正常工作：

  func startRecording() {
        fileName = String(format:"AudioFile%d.m4a",k)
        k = k+1

        let audioFilename = getDocumentsDirectory().appendingPathComponent(fileName)
        address.append("\(audioFilename)")
        print("adress = %s",address[num])
        num = num + 1
        let settings = [
            AVFormatIDKey: Int(kAudioFormatMPEG4AAC),
            AVSampleRateKey: 12000,
            AVNumberOfChannelsKey: 2,
            AVEncoderAudioQualityKey: AVAudioQuality.high.rawValue
        ]


        do {
             try session.setCategory(AVAudioSessionCategoryPlayAndRecord, with:AVAudioSessionCategoryOptions.defaultToSpeaker)
            try session.setActive(true)
            SoundRecorder = try AVAudioRecorder(url: audioFilename, settings: settings)
            SoundRecorder.isMeteringEnabled = true
            SoundRecorder.prepareToRecord()
            SoundRecorder.delegate = self
            SoundRecorder.record()

        } catch {

        }
    }

我不知道该怎么办，有什么办法可以通过快速或客观C来做到？任何建议都将不胜感激。

要录制不同的AudioKit节点，请使用AKNodeRecorder。 AudioKit附带一个“记录器”示例项目：
