Abstract: This paper describes an approach to building an audio conferencing application for Android smart phones. As the need for audio conferencing systems grows and smart phone market penetration has increased, the smart phone has become a viable platform for developing conferencing applications. We have implemented a centralized audio conferencing model and developed a client application which was deployed on Android-based smart phones. Experiments for battery consumption and packet delay were designed to evaluate the usability of the application. The smart phones were not affected by the application under low traffic conditions; however, the application did consume twice as much battery life under heavy traffic conditions. The results for delay testing showed that increasing the number of participants also resulted in longer packet average delays. Throughout the development process, problems involving software/hardware diversification and audio signal processing were un-covered and potential solutions were proposed. The paper provides valuable information for develop-ing VOIP applications on smart phones, specifically on the Android platform, and can direct future de-velopment of audio conferencing systems.
