Mobile recording app
Hi, my friend installed a recording app on his mobile phone. When he talked to his friend, their conversations were recorded. However, when he replayed the recorded conversations, he could hear his own voice only, couldn't hear the voice of the other party. Can anyone restore the voice of the other party? Totally 2 recorded conversations i.e. 2 recorded links. Total price: $25. Thank you.
Have experience in this particular field.
