Authentication of Audio files is one of the key functions in forensic sciences and many criminal investigations. Over the past few decades, audio recording has completely shifted from analog recording to digital recording, allowing more freedom for forensic experts to extract information. The details that can be extracted from audio files include:
Voice Identification
One of the key pieces of information extracted from an audio file is identifying an individual’s voice. Just like everyone has unique fingerprints, we also have unique voices. You can easily extract someone’s voice from an audio file, and using voice biometrics, we can compare that voice to the targeted voice. We can identify the slightest of voices to identify the person it belongs to.
Authentication
There are a lot of cases when people tamper audio files for their causes. There have been instances when people have done that during legal cases. However, we can identify whether the audio file is authentic or not with the help of metadata. We analyze the audio file to identify the data it was created, the device used to record it, and the software used to edit it. This is enough information for us to conclude if it’s tampered with or not.
Critical Details
Another major part of the information extracted from an audio file is the critical information about the surrounding. You can divide the processing into different parts to hear every aspect of that audio file. Audio enhancement experts will process the audio file and improve the quality to the point that you’d be able to listen to the minutest sounds in the background, including people whispering.
