audiokit录音机第一次录音，第二次不再录音

Question

这是我第一次使用audioKit。顺便说一下，很棒的框架

我能够录音，工作得很好。

 func prepareToAKrecord() {
        // Setup microphone and reverb
               mic = engine.input
               reverb = Reverb(mic)
                reverb.loadFactoryPreset(.mediumRoom) //large hall etc
               engine.output = reverb

        do {

            // Check if the recorder is already recording
                    if recorder?.isRecording == true {
                        print("Recorder is already recording. Attempting to stop before reinitializing.")
                        recorder?.stop()
                    }
            

                    // Reset the recorder if it exists
                    if let existingRecorder = recorder {
                        try existingRecorder.reset()
                        print("Recorder reset successfully.")
                    }
            recorder = try NodeRecorder(node: reverb, shouldCleanupRecordings: true)
             try self.engine.start()
             try self.recorder!.record()
        } catch {
            print("Failed to create recorder: \(error)")
        }
        
    }

然后我就停下来

    func stopAKRecordingAndSave() {
        self.isRecording = false
        
       
        //recorder!.stop()
        recorder.stop()
        engine.stop()
        
        if let recordedAudioFile = recorder!.audioFile {
            self.voiceURL = recordedAudioFile.url
            print("Recording saved to: \(self.voiceURL!)")
            //dec-4
            self.mergeVoiceSong() // Merge this voice reverb and backing track
            //self.merging = false
        } else {
            print("Failed to get the recorded audio file")
        }

        UserDefaults.standard.set(false,forKey: "newSearch")

    }

但是如果我尝试启动引擎并再次记录则不起作用，即使我执行了 record.reset()

我是否缺少清理总线的特殊方法？我应该保持发动机运转并重置吗？

我第二次尝试录制时收到一堆警告

Answer 1

保持引擎运转并在没有混响的情况下尝试。只要您不停止引擎并且它不抛出错误，它就会运行。

考虑您的节点链在应用程序的各种条件下的外观。
