Digital Audio Authentication

Digital audio authentication is the scientific process of analyzing an audio recording in a forensic laboratory. During this process, we learn how a recording was created. We also learn about the meta data and integrity of the audio recording.
It is fairly easy to download an audio editing program like Audacity and edit a portion from an audio recording. When editing occurs, a conversation intention has changed. Words are removed or other conversations merged. This is why digital audio authentication is important if you have an audio recording to be used in a litigation.
