Virtual Spatial Hearing

HRTF
Locating a sound in space involves more than amplitude, time and phase differences, i.e the traditional factors that account for stereo localization.
People distinguish between subtle variation in frequency distribution as directional cues, rather than as changes in the timbre of the frequency of the sound source. These direction-based changes caused by the pinna, plus other caused by head shadowing and reflections, are collectively referred to as head-related transfer functions (HRTF).The pure directional parts hereof are also termed directional transfer functions (DTF).

Virtual Spatial Hearing
Virtual surround systems use HRTF techniques to map the 5.1 discrete channels of sound into virtual space with only two speakers. An obvious goal is to re-create the sensation of listening to multiple speakers. But, with HRTF techniques it is also possible to improve the sensation of spatial hearing which is more than multiple speaker based systems can do.

Pseudo Spatial Hearing
Describes the derivation of more channels of sound than originally available from a record. If you are looking for the separation of mono/stereo signals into a multichannel environment please go to Music Effects.

Platforms
Object-Code libraries are available for audio applications on PC based platforms. We offer also DSP engineering to integrate our algorithms on embedded platforms.
Furthermore, it is well known that non individualized HRTF can be improved through customization, which is possible in the context of our technology.
