A simulation study on clandestine audio recording

초록

In this paper, the effectiveness of clandestine audio recording with respect to different placements of recording devices was evaluated through a simulation study. Audio samples from prospective placements and methods of clandestine audio recording were analyzed, and finally the optimal configuration was suggested in this paper based on waveform analysis. Existing methods of clandestine audio recording were first investigated and analyzed in order to identify their problems, and then to suggest an improved method to solve these problems. The result of this research shows that there is an optimal position of recording devices for clandestine audio recording and that we may use an improved recording method for better performance. The result can be applied to areas including the use of personal audio blackboxes for keeping records for legal disputes and the protection of national security from potential espionage. © 2014 SERSC.
