We work with a cyber forensic team. We have received a AMR format audio file from a mobile that has some conversation between two parties. Now we have to prove that the clip that the party one is showing to us is not the entire audio clip and that they have done some editing and removed some part of the conversation, so that the outcome of that conversation sounds negative.
How can we prove that the file is edited..? We don't have the original file with us.?
