how to make 2 recording apps work at the same time?

  android, call, call-recording, input, microphone

I have 2 call recorders app in my phone . Usually, one works and the second doesn’t work . I need them to record both and at the same time . I read in a post that I need an intermedate layer to bring the original soung from microphone then distribute it to apps so that they can work at the same time . Is there any app that does this work ? or do I need a codage ? Any idea ? I’m not a developper so my knowledge in programmation is weak . Any answer is very appreciated . Thank you in advance .
