Audio authentication is the process of determining if an audio recording is authentic or if it has been tampered with/edited. The first step is to establish a chain of custody. A chain of custody does not, in and of itself, establish a recording as being authentic. Audio evidence preserved in the original device has more digital integrity to pass authentication testing.
