Is it possible to record Audio in minimized state UWP

I need to use voice recording in UWP But if App is minimized then recording doesn't work.

Is there any way to do that, without using restricted capability?

Use ExtendedExecutionSession. It will allow your uwp app to record the audio while minimized. Here is link https://learn.microsoft.com/en-us/windows/uwp/launch-resume/run-minimized-with-extended-execution for details. I have tried and it works fine for me. Add EnteredBackground and LeavingBackground event:

        this.EnteredBackground += AppEnteredBackground;
        this.LeavingBackground += AppLeavingBackground;

When detecting the event, call BeginExtendedExecution and when session is allowed, call capture audio function.

   private async void BeginExtendedExecution()
    {
        ClearExtendedExecution();

        var newSession = new ExtendedExecutionSession();
        newSession.Reason = ExtendedExecutionReason.Unspecified;
        newSession.Description = "recording audio";
        newSession.Revoked += SessionRevoked;
        ExtendedExecutionResult result = await newSession.RequestExtensionAsync();

        switch (result)
        {
            case ExtendedExecutionResult.Allowed:                   
                session = newSession;
                RecordingAudio();

                break;
            default:
            case ExtendedExecutionResult.Denied:                    
                newSession.Dispose();
                break;
        }
       

    }
