Audio forensic marking for music streaming service
2013 International Conference on ICT Convergence (ICTC), 2013In this paper, we propose an audio forensic marking scheme suitable for music streaming service. To support the real time forensic marking embedding, our scheme consists of preparation stage and composition stage. We verified performance, robustness, and imperceptibility of the proposed scheme through some experiments.

Audio forensics from gunshot for firearm identification
The 4th Joint International Conference on Information and Communication Technology, Electronic and Electrical Engineering (JICTEE), 2014The gunshot blast is one of the evidences used to identify the criminal gun in the shooting scene. We proposed a method of using the gunshot blast to identify the firearm caliber in terms of audio forensics. The experiments were performed on the database consisting of 80 audio files of gunshot sounds fired from 8 different guns.

The ability to perform audio forensic analysis hinges on the availability of audio recordings made outside the confines of a recording studio. The first portable recorders using magnetic tape appeared in the 1950s, and soon these devices were used to obtain clandestine recordings of interviews and wiretaps, as well as to record interrogations and ...

A Forensics System for Live-Audio Watermarking
2020 International Symposium on Electronics and Telecommunications (ISETC), 2020A common problem in audio forensics is the difficulty to authenticate an audio recording. You can have an argument against any audio probe. In this paper we propose a system that can take audio probes which can be used with success in a court. The recording will be bulletproof due to the use of a reference protocol based on an external entity, the ...

Study of Wireless Channel Effects on Audio Forensics
2016 22nd Annual International Conference on Advanced Computing and Communication (ADCOM), 2016In this work, we try to study the effect of a wireless channel on physical parameter prediction based on speech data. Speech data from 207 speakers along with corresponding speaker’s height and weight is collected. A three path Rayleigh fading channel with typical values of Doppler shift, path gain and path delay is utilized to create the mobile ...

Interview with visually impaired forensic audio analysts
2016In order to address the question whether blind individuals are particularly suitable for working in the field of forensic phonetics, it was considered necessary to first look at the current situation of blind individuals who are already employed in law enforcement institutions. (For a discussion of the topic, see section 9.10 and Chapter 10).

AI-generated synthetic audio analysis and forensic attribution
This thesis addresses critical issues in synthetic audio forensics and voice privacy protection, focusing on two main areas: synthetic audio attribution and the resilience of audio cloaking techniques against adversarial inversion attempts. With the increasing use of synthetic audio in digital media, there is an increasing need for robust methods to ...Yong, Guan +2 more
