Recent reports show that there is a 40-200 millisecond delay for sound playback in Android devices. At the same time there is no such reports and identified problem for other platforms. Research focuses on unresolved audio playback latency problems in devices with Android operating systems. Examination of possible problems, application of audio playback latency recording and measuring methods and audio playback latency decreasing methods are used to achieve a smallest possible audio playback delay. As a result with a proposed solution audio playback delay was reduced to 9ms using OpenSL EU API application and uncoded audio data with a device that support digitization and most high performance.
