Efficient Integration of Audio Effects in Android 2.3

Android is a new mobile platform for mobile development, It has a rich set of applications. Android multimedia architecture is improving day by day. Multimedia applications are become very important part for the success of any mobile platform. Every day new idea is researched to improve the quality of audio/video for mobile platform. A part from quality, battery power management is also important. Battery power is always on the top of the requirement stack. In current android multimedia architecture, audio effects are handling with Advance RISC Processor (ARM), which is core processor of mobile devices. In this thesis research work, a new framework for the audio routing has been proposed. The change in audio routing stack is proposed to save the battery power. Audio effects are integrated with the help of digital signal processor instea of ARM processor. New algorithm for the Bass booster and Virtualizer Audio Effects are implemented with respect of proposed framework. The power consumption of these audio effects are tested in the current and proposed android audio multimedia .The power consumption in proposed framework is less as compare to the current framework .
