Recordings involving cellular telephones or personal digital assistants (“PDAs”) are increasingly the source evidence in audio forensic examinations, compared to recordings originating with other devices such as hand-held digital recorders. On modern PDA cellular telephones recordings can be made either directly to the telephone or transmitted as voice mail messages. The current investigation focuses on differences in the two types of recordings in terms of dynamic range and linearity of levels. Such information can be important for characterizing the distance of sound sources relative to the microphone and are important for understanding transformation of recorded speech and non-speech sounds.
Written by an author with expertise in both theory and applications, 3D Sound for Virtual Reality and Multimedia provides readers an essential technical foundation in sound and virtual reality. The book covers components of spatial auditory displays; psychoacoustics of spatial hearing; what sounds are appropriate to spatialize; applications to human-machine interfaces (including virtual reality and multimedia); computer music; and room acoustics.
