Abstract

Audio is one of the digital items that can
reveal a happened case. However, audio evidence can
also be manipulated and changed to hide information.
Forensics audio is a technique to identify the sound’s
owner from the audio using pitch, formant, and spectrogram parameters. The conducted research examines
the similarity of the original sound with the manipulated
voice to determine the owner of the sound. It analyzes the
level of similarity or identical sound using spectrogram
analysis with the Digital Forensics Research Workshop
(DFRWS) Method. The research objects are original
and manipulated files. Both files are in MP3 format,
which is encoded to WAV format. Then, the live forensics
method is used by picking up the data on a smartphone.
Several applications are also used. The results show
that the research successfully gets digital evidence on
a smartphone with the Oxygen Forensic application. It
extracts digital evidence in the form of two audio files and
two video files. Then, by the hashing process, the four
obtained 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.
