Audio recording on interpretation mode

Hi everyone. I´m interpreter and when I record a meeting on my computer, like co-host, my voice and the voice of the peroson I´m interpreting, are recorded with the same volume. And it´s almost impossible to hear and understand the translation. Dose anyone knows if there is an option to record the original video, but only my voice? I have this option to save it like separates audio, but this doesn´t help me, becasue I need the video too. Thanks!!!
