SoC 2007 Project Audio Extensions
This project is part of Google Summer of Code 2007.

Introduction
The audio output of sound systems can be improved using signal processing techniques which control the frequency response, amplitude, and phase of the output signal. This project is in two stages. In the first stage, the output of VLC media player will be enhanced using similar concepts in other patented systems such as SRS(sound retrieval system), in order to provide a better listening experience.
The second stage involves creating an immersive audio experience, which is a desirable feature in any sound reproduction system. This is currently implemented in multichannel audio reproduction technologies such as Dolby Prologic 2. These multichannel technologies typically require multiple speakers in the equipment setup. The first project will emulate the listening experience obtained from multichannel systems using only a pair of speakers.
Approach
The desired immersive audio synthesis will be achieved using the head related transfer function (HRTF).
