MPEG-4 Structured Audio (SA) [1] defined a set of tools to provide high quality low bit rate audio. In MPEG-4 SA, SAOL (Orchestra Language) is the most important part because it is used to implement algorithms to generate sounds. However, SAOL must be translated into other programming languages such that it can be executed currently. This requires lots of computing power to achieve real-time decoding. Based on MPEG-4 SAOL, we propose JavaOL because it eliminates the translation process and is more efficient. In fact, it is Java equipped with SAOL opcode library. Therefore, one can achieve the same functions provided by SAOL. We also provide a RTP streaming engine and the associate player. Software tools are provided to combine other audio sources.
