I have an audio that was automatically recorded with a mobile app. The problem is that this app also record the audio from the background. I was with the TV on this day and both audios mixed, turning the voice of the other part hard to hear. My voice is okay.
I tried to edit it myself with audacity but the result was a crap, so I need someone with better knowledge to do the trick.
In the first 5 seconds you can hear both my voice and his. At the background you can hear the noise from the TV that goes high sometimes.
