Audio recording rises access violation on IOS 13.5.1

[OldyCoder 0]

I'm using following code snippet to record audio on IOS 13.5.1 and getting access violation exception.

My Delphi version is 10.3 Update 3.

It works fine on Android.

 

  Mic := TCaptureDeviceManager.Current.DefaultAudioCaptureDevice;

  if (Mic <> nil) then   begin
    Mic.FileName := 'record.mp3';
    try
      Mic.StartCapture;
    except
      on E: Exception do
        lblError.Text:=E.message;
    end;
  end;

Is there any workaround?

Is there a value for NSMicrophoneUsageDescription in the Project Options, like this?

 

 

If not, you'll need to add it, by right-clicking on the grid, click Add Key, enter NSMicrophoneUsageDescription as the name, click OK, then provide a value for it.

Thank you Dave.

The problem was caused by audio format that I used.

IOS does not support mp3 audio format. IOS supports only caf format.

 

Yes my new problem is:

How can I convert caf to mp3 on IOS 😊
