Abstract

Audio is one of the digital items that canreveal a happened case. However, audio evidence canalso be manipulated and changed to hide information.Forensics audio is a technique to identify the sound’sowner from the audio using pitch, formant, and spec-trogram parameters. The conducted research examinesthe similarity of the original sound with the manipulatedvoice to determine the owner of the sound. It analyzes thelevel of similarity or identical sound using spectrogramanalysis with the Digital Forensics Research Workshop(DFRWS) Method. The research objects are originaland manipulated files. Both files are in MP3 format,which is encoded to WAV format. Then, the live forensicsmethod is used by picking up the data on a smartphone.Several applications are also used. The results showthat the research successfully gets digital evidence ona smartphone with the Oxygen Forensic application. Itextracts digital evidence in the form of two audio files andtwo video files. Then, by the hashing process, the fourobtained files are proven to be authentic. Around 90%of the data are identical to the original voice recording.Only 10% of the data are not identical.
