Recording FaceTime with Audio Hijack 3

Hi

I'm trying to record a FaceTime conversation using the full licensed version of Audio Hijack 3 on my MacBook Air. I'm using FaceTime as an input and also my mic as an input. I hear myself clearly and there is no echo. But the FaceTime caller, well, that's either distorted or there is an echo. I've turned off the recorder for my mic because that was making things worse. What should I do? I'm stumped. Thank you
