This paper presents a generic and customizable 3D audio engine, which has been specially designed for gaming on low-end mobile devices. The engine is based on source and listener 3D positioning for headphone playback. Distance attenuation, Doppler effect and reverberation can be added to fit JSR234 specifications. In order to address platform diversity, we have developed a PC application to easily design the best 3D audio engine in accordance with processor capabilities. Standard HRTF based processes have been simplified to obtain a limited number of fixed point IIR filters, which have been successfully implemented on several platforms. Then, objective and subjective validation methods allow us to certify the quality of the porting.
