Core tip: Background introduction opensl ES is a hardware audio acceleration API specifically optimized for embedded systems, with no licensing fees and can be used across platforms. It provides a high-performance, standardized, low-latency feature implementation that provides standards for embedded media development, and embedded developers are also making it easier to develop native audio applications that enable the use of the API for software/hard
