assume that we have a 10:00 minutes conversation audio file and that you are suspecting that this file was cutted from the minute 5:00; in other words, the person who gives you tath file has probably used an audio editor to delete the first 5 minutes. So, this file is not created with i.e. a smartphone voice recorder but by an audio editor program. How can I check it? Is a audio-spectrum or a particular audio analyzer that can check this?
Thank you very much!
PS: the problem is not, a central part is cutted and the first and last are merged (in this case is easy check a discontinuity of spectrum). The problem is that, the entire start part is cutted.
