Abstract

Power consumption is an important issue while listening to music using portable audio devices. The authors have previously proposed a power-saving audio playback algorithm, which has adjusted filter-bank outputs according to our auditory characteristics. It succeeds in reducing power consumption but causes perceptual distortion. In this paper the power-saving audio playback algorithm is improved based on auditory masking, which attenuates audio components below the masking threshold. As a result of a listening test, it is confirmed that the proposed method is subjectively superior to the previous method with the same power consumption.
