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.
Systems for extracting voice input from ambient noise (notably telephones, speech recognition systems, hearing aids) Surround sound and related technologies; Binaural recording; Locating objects by sound: acoustic source localization, e.g., military use to locate the source(s) of artillery fire. Aircraft location and tracking.
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.
While the relationship between human perception of sound and various attributes of the sound field is not yet well understood, [2] DSP algorithms for sound localization are able to employ several mechanisms found in neural systems, including the interaural time difference (ITD, the difference in arrival time of a sound between two locations), the interaural intensity difference (IID, the ...
Sound localization is a listener's ability to identify the location or origin of a detected sound in direction and distance. The sound localization mechanisms of the mammalian auditory system have been extensively studied. The auditory system uses several cues for sound source localization, including time difference and level difference (or ...
OpenSL ES (Open Sound Library for Embedded Systems) is a royalty-free, cross-platform, hardware-accelerated, C-language audio API for 2D and 3D audio. It provides access to features such as 3D positional audio and MIDI playback. It is made for developers in the mobile and gaming industry and is working toward allowing for easy porting of ...
Disney Sound Source – a different design to the Covox Speech Thing, though in a superficially similar case also with parallel pass through, marketed by Disney Software in early 1990s. Consists of a FIFO buffer with a DAC on the board that plugs into the parallel printer port, which transmits analog audio over a registered jack to a separate ...
The Composers Desktop Project (CDP) is an international cooperative network based in the United Kingdom that has been developing software for working with sound materials since 1986. Working on a cooperative basis and motivated by user-specific compositional needs, the project has focused on the development of precise, detailed and multifaceted ...
