Abstract: In this thesis, we study perception-aware low power audio processing techniques for portable device. These works are mainly motivated by the fact that the audio decoding application is a significant source of energy consumption in context of portable devices. Compared to video, audio decoding applications have different characteristics and more critical requirement on playback quality. Targeting low power audio decoding, we first propose a new conceptual methodology framework. Based on this methodology framework, we have developed three schemes: 1) a joint encoder-decoder framework (JEDF), which allows the decoder to have a desirable tradeoff between energy and storage consumption without sacrificing playback quality; 2) a new scheme of media server supporting DVS for low power multimedia decoding; and 3) a frequency Band and Stereo-image Scalable (BSS) decoding framework, which achieves workload scalability based on an analysis of the perceptual relevance of different audio components.
