Audio forensics is a very important part of the investigative process. It can help determine if you have a case, or it may be your only piece of evidence to show that an incident did take place. Audio forensics can also be instrumental in proving that a crime was committed.
Audio forensics is a complicated field where there are many different types of experts who specialize in different aspects of audio analysis. The best audio forensic service providers will understand the processes involved, as well as how to use them effectively to build evidence that can stand up in court.
The best audio forensic service providers will have their own set of experts who specialize in different areas such as voice recognition, transcription and acoustic analysis. They will also be able to use their expertise to enhance the quality of any audio evidence before presenting it in court or submitting it as part of an investigation report.
Garrett Discovery is an expert in audio forensics and has a wide range of services to help you. We offer forensic services for both audio and video evidence, including:
Audio Authentication: When it comes to authenticating recorded conversations, we understand that it’s not enough to just know the content of the recording. We know what can make it sound real and what can make it sound fake. Our team of forensic experts has years of experience in audio analysis, voice recognition, and audio enhancement to help you determine if your recordings are authentic or fake.
Voice Recognition: Voice recognition software is capable of recognizing specific voices from recordings in addition to identifying their locations. This allows us to identify speakers, unique characteristics and even distinguish between multiple speakers in a recording. We also use voice recognition technology to enhance your audio files so that they sound more natural than ever before.
Audio Enhancement: Audio enhancement software works by enhancing weak or distorted parts of an audio file so that it can be heard clearly again without having any issues with intelligibility or clarity. By using this type of software on your recordings, you’ll be able to hear everything clearly again without losing any important details.
The Fundamentals of Audio Forensics Evidence
Audio forensics is the forensic examination of audio evidence to help determine its authenticity. This includes the identification of speakers, their locations and other characteristics such as ambient sound and background noise.
The fundamentals of audio forensics evidence are:
The integrity of the original recording – Audio forensics evidence is often used to authenticate recordings made by witnesses at a crime scene or by police officers in the field. If the recording has been altered, then it cannot be used as evidence in court.
The quality of the recording – The quality of an audio recording can often be determined by testing its bit rate and sampling rate, which are two factors that affect sound quality. Bit rates are expressed as kilobits per second (kbps), while sampling rates are expressed as samples per second (sps). The higher these numbers are, the higher quality sound you’ll hear on your device or computer speakers/headphones when playing back your media file/file transfer between computers/mobile devices/radios etc.
