Android Framework Implementation of 3D Audio with Range Control

Due to the rapid improvement in processing power of mobile devices, real-time 3D audio rendering is becoming a reality on these devices. Using 3D audio rendering, many interesting applications, such as teleconferencing and immersive gaming can be developed. In this paper, an Android framework is developed for rendering 3D audio in real-time with additional range control. Range-dependent head related transfer functions (HRTFs) are used in order to render the spatial audio. Distance dependent HRTFs are extremely tedious to be measured since these measurements have to be carried out for several distances in the near-field. In this work, the range-dependent HRTFs used by the Android framework are experimentally measured in the horizontal plane and made available online for the researchers to use. This 3D audio framework will serve as a useful platform to deliver new audio processing applications, such as teleconferencing over headphones, personalized hearing in gaming and virtual reality etc.
