ABSTRACT: In this paper, we present objective and subjective evaluation of AAC audio codec implementations for ARM based audio mobile device. Selected audio material was coded and decoded using implementations provided by four different vendors and then compared to the original audio recordings by using EAQUAL software. Afterwards, two implementations with highest scores were evaluated by using subjective A/B/X listening test. Finally, the optimal choice of codec and bitrate was made, based both on subjective quality of the codecs and on other important objective indicators such as processor usage and memory occupation of ARM architecture implementations.
