The demand for audio performance in mobile devices has been steadily increasing. For example, Mastering Quality Sound (MQS) (192 KHz/24 bit) audio playback, advanced and realistic sound effect such as Dolby DS1 and DTS Headphone:X, and voice recognition. However, increase in audio performance could be unfavorable news for the battery life of the device. Samsung Exynos processor offers market-leading audio playback time with separate audio subsystem and strives to provide better performance and lower power consumption. This paper describes the efforts of Samsung and its preparation for high performance/low power audio for the future.
