Recent developments in the audio- authentication field include basic, preliminary audio analysis and advanced audio- authentication techniques that exploit audio recording conditions and compressed audio features. Multimedia is involved in every aspect of our lives, and many of us rely on various websites for information on events taking place all over the world. 

We form opinions based on the content of camera footage, phone conversations, and other recordings. Although some sources give us authentic information, others contain forged content. Concerns regarding how to authenticate multimedia data have led to research in forgery detection, but studies in audio are generally still limited compared to those in image and video.
