A general way to implement 3d sound localization is to use the HRTF(Head-related transfer function). First, compute HRTFs for the 3D sound localization, by formulating two equations; one represents the signal of a given sound source and the other indicates the signal output from the robot head microphones for the sound transferred from the source.
Bio-acoustic software Name License Platform Details Audacity [1] GPL v2: Linux, Macintosh, Windows: General purpose audio editing tool. Anabat Insight [2] Proprietary Windows, Macintosh Designed for bat call analysis; allows users to view, listen to, manage, search, analyse, and report on recordings in full spectrum or zero crossing.
The ILD arises from the fact that, a sound coming from a source located to one side of the head will have a higher intensity, or be louder, at the ear nearest the sound source. One can therefore create the illusion of a sound source emanating from one side of the head merely by adjusting the relative level of the sounds that are fed to two ...
Acoustic source localization [4] is the task of locating a sound source given measurements of the sound field. The sound field can be described using physical quantities like sound pressure and particle velocity. By measuring these properties it is (indirectly) possible to obtain a source direction.
3D sound reconstruction is the application of reconstruction techniques to 3D sound localization technology. These methods of reconstructing three- dimensional sound are used to recreate sounds to match natural environments and provide spatial cues of the sound source.
An application of 3D sound synthesis is the sense of presence in a virtual environment, by producing more realistic environments and sensations in games, teleconferencing systems, and tele-ensemble systems. 3D sound can also be used to help those with sensory impairments, such as the visually impaired, and act as a substitute for other sensory feedback.
SDL Passolo is a software localization tool, developed by SDL plc, that is customisable to the users' needs; requiring no programming experience. It allows users to concentrate on the translation by accelerating the many technical aspects of software localization, and it is possible to work in a WYSIWYG (What You See Is What You Get) mode.
These effects include localization of sound sources behind, above and below the listener. Some 3D technologies also convert binaural recordings to stereo recordings. 3D Positional Audio effects emerged in the 1990s in PC and video game consoles. 3D audio techniques have also been incorporated in music and video-game style music video arts.
