我正在使用AVCaptureAudioDataOutputSampleBufferDelegate捕获音频_captureSession=[[AVCaptureSessionalloc]init];[self.captureSessionsetSessionPreset:AVCaptureSessionPresetLow];//SetupAudioinputAVCaptureDevice*audioDevice=[AVCaptureDevicedefaultDeviceWithMediaType:AVMediaTypeAudio];AVCaptureDeviceInput*captur

我正在尝试使用它编译和运行的AVCaptureDevice等来调整音量级别，但这些值似乎是随机的，而且我也不断收到溢出错误。编辑:另外，RMS范围在0到20000左右是否正常？ifletaudioCaptureDevice:AVCaptureDevice=AVCaptureDevice.defaultDeviceWithMediaType(AVMediaTypeAudio){tryaudioCaptureDevice.lockForConfiguration()letaudioInput=tryAVCaptureDeviceInput(device:audioCaptureDevice
