Due to the widespread use of smart mobile devices, phone recording software, and surveillance equipment such as IP cameras, audio recording has become a common form of evidence in legal proceedings and a helpful tool for police investigations and private detective work. The authenticity and credibility of audio files are particularly important and critical for such purposes.
However, the increasing popularity of video and audio editing software and the ease of access to relevant hardware and software have led to a surge in file editing and evidence tampering. This has seriously affected the ability to reconstruct the truth of events and the fairness of judicial decisions.
Recognizing the rampant misuse of video and audio editing software and techniques and the excessively lax adoption and evaluation of audio evidence by legal and investigative organizations, the MuScene Voice Forensics Laboratory continues to conduct research and experiments to identify evidence tracks induced by digital data editing and tampering. We also provide technical services and investigative assistance to the Private Sectors in related fields.
With incessant improvements and updating of video/audio editing software, rapid development of digital file decoding, signal processing algorithms, and increasingly advanced editing and forgery techniques, the MuScene Voice Forensics Laboratory continues to invest human and material resources to engage in cutting-edge sound processing technology research, professional training, and file tampering evidence research. Through the team's advanced audio processing technology, the MuScene team conducts file editing and forgery simulations for generating tampering characteristics and develop automated detection approaches through reverse engineering, thereby upkeeping the MuScene Voice Forensics Laboratory with the most advanced techniques for detecting digital data manipulation.
The US tech-based MuScene Voice Forensics Laboratory has a wealth of practical forensic experience and related theoretical foundations. We have conducted in-depth research in areas such as acoustic physics, psychoacoustics, spatial acoustics, linguistics, phonology, phonetics, speaker feature extraction, speaker recognition, signal-to-noise control, noise reduction, frequency and sound information extraction, sound synthesis and tampering inspection, audio signal enhancement, environmental ambiance noise analysis, file conversion, audio compression, audio encoding and decoding.
Back in 2013, the MuScene Recording Studio, the parent company of MuScene Voice Forensics Laboratory, was aware of the drastic domestic imbalance between customer demands and service providers in the broad scope of recorded audio evidence and started to prepare for entering into this new trade of technical services, and by 2015 we officially founded the Voice Forensics Laboratory. Since then, all forensics related business previously provided by the Studio, including consulting, speaker identification, analysis, speech signal enhancement, basic research, and development, have been transferred to the laboratory for continued expansion of our capacity in research and service quality. Outsourcing services demanded by regional courts and impartial third-party forensic notarization institutions are also among our service scope.
Important message for potential customers: as data originality is of vital importance to recorded audio evidence, KEEP YOUR ORIGINAL COPY OF RECORDED EVIDENCE INTACT before you are instructed by one of our engineers as to how to submit your data for evaluation; simple operations such as file copy may sometimes inadvertently result in data modification with ensuing loss of its probative power. All data manipulation should only be handled by personnel trained for such operation!
To have your recorded audio data processed by the MuScene Voice Forensics Laboratory, you need to prepare and submit the following:
1. An authentic copy of the digital source audio file,
2. A written description/summary of the nature of serve you’re looking for,
3. In the case of speaker identification, a recorded speech of the subject person with quality no worse than that of your subject audio recording, otherwise, a legal and mandatory speech exemplar must be scheduled.
4. Transcript of the recorded speech with accurate speaker annotation.
