This paper presents an asynchronous dithering scheme based on bit expansion subtractive dithering as well as bit expansion non subtractive dithering algorithm to enhance the quality of digital audio playback. The bit expansion asynchronous dithering system is suitable for implementation on both portable CD players and Hi-Fi systems with improved sound quality with enhanced performance in tone, smoothness and dynamic range. This scheme is particularly appealing to portable CD players due to its relatively low power requirement.
